15 Tips To Speed Up Your Computer

Finding ways to speed up your computer is the most important thing you could do as a computer user. This might save your computer from being thrown out the window, or even smashed up with a hammer. This is how far people get pushed when computers don't do what they computers don't do what they want them to do. It is one of those annoying little things that you have to do all the time, maintenance jobs, just to speed up your computer.

When you have a slow computer and you are trying to work on it, you can easily get frustrated to the point of doing something drastic! Hey but clam down ! I have to tell you something truthfully. It's your fault that your computer is slow because you do not perform computer maintenance on it. It is your responsibility to speed up your computer and make it run an its optimal performance. Don't go blaming the computer because it is slow, follow these steps below and fix your problem now!

15 tips on how to speed up your computer

Delete unwanted files

When I says to delete unwanted files, I do not mean you should go around your computer and delete any file you do not want. In this case, I'm talking about the files that you have created yourself, and are totally aware of what they are. For example if you created a Microsoft word document and you no longer need it, and never will, then I suggest you delete that file. This is the kind of junk that clogs up your computer. You have a ask yourself, " Do you really need it?"

Files that you have created such as documents and image files can be safely deleted by going to the file on your computer, right clicking on its, and choosing delete from the menu. Keeping your computer or organized and junk free, is a great way to speed up your computer.

Delete hidden junk files

Hidden or temporary files are created without the user knowing. All you have to do is open files, browser the Internet, Install programs, and more files are created in the background. There is so much happening in the background that most people are unaware of and do not know that this area exists. This is something you are going to have to learn about if you want to speed up your computer.

Remove Unwanted Programs

Are you one of those people that constantly download programs and install them on to your computer? Every software program you have on your computer is taking up space. It is not only taking up space, but it might also be checking for updates and connecting to the Internet. It also might be starting up when your computer starts up. There are so many good reasons why you should remove unwanted programs.

After you have removed the software program that you did not want, make sure you restart your computer the process.

Defrag to speed up your computer

Check & Fix system errors; Speed Up your PC by 300% times!

When you install programs and save files on your computer, the files are automatically saved to the closest available space on your hard drive. This means that files for your programs are fragmented if your hard disk drive is not organized correctly. This is why we need to de-frag our computer to place the files back together and to place the most frequently used files at the front for easy access.

You should defrag your computer at least once a week if you use your computer often. If you do not use your computer that often then you can defrag less often.

If you are using the Windows disk defragmenter which is located at start menu>>Accessories>>System tools>>disk defragmenter, you can choose to "analyze" first before you choose defrag. This feature will tell you if you need to perform this task or not.

Disk Clean Up

Disk CleanUp comes free with Windows and will get rid of the rest of the junk files that you have missed. Go to Start menu>>Accessories>>System tools>>Disk Cleanup.

Always pay for a virus program!

By all means, you can waste your time trying to find the best free anti-virus program,but do you really want to risk it.

Don't get me wrong there is nothing wrong with a free anti-virus program. In fact I will recommend Avast as my number one freebie. However, even though this provided to be secure, it is safer to have the extra security features that come with the paid versions. Now days most new antivirus also come with a firewall that if they do not, Windows provides a perfectly good firewall for free.

Over the past 25 years I have tested at least 10 paid virus programs and have ended up with Avast running on my computer. It does not annoy me, it is not asked be stupid questions that I cannot asnwer, and is not make me deal with difficult settings. I like a peogram that just does its job.

Avoid multitasking with large programs

If you're anything like me, you will have 20 windows open at the same time, with your Internet browser having at least 15 tabs opened as well. Yes I know it is crazy and I/m trying to reform. I have a lot of experience in multitasking and have realized that some programs cannot be open at the same time as others. For example you should not be running a large program like Photoshop or Pinnacle video studio, while running a virus scan at the same time.

How to share Internet Connection

2011-06-25T07:56:00.000-07:00

How to Share internet Connection at home is a FAQ for some- people who subscribe the cable /DSL Internet services from the ISP.

Pros:

Simple network, one modem and one Switch LAN
Less knowledge about network configuration experience

Cons

This configuration is not practical since you have to configure the TCP/IP protocol property each of the computers with static IP address unless you deploy a DHCP services on your network. A pure modem does not have a DHCP service feature.
Your network is vulnerable to the internet threats, no protection at the gateway such as firewall.

A router integrated with modem

Technology provides you many options and advanced features you can buy to deploy internet connectivity to share internet connection with multiple computers at home or at the office. Mostly all the networking manufactures introducing Router-modem - an integrated router with ADSL or Cable modem, for example D-Link introduces WBR2310 RangeBooster G DSL - Cable Router which consists of modem, router / firewall, switch, and wireless access point function. Or you can consider DGND3300 Wireless DSL modem / Router. DGND3300 is a dual-band RangeMax Wireless-N modem / router which deliver better connections with less interference.

Pros

A single compact device to purchase with multi-functions provides you all the requirements to build a simple network at home.
The device includes all the services the network needs such as DHCP services, secure wireless connection, and firewall protection (NAT & SPI) and so on.

Cons

A single point failure
Less advanced features compared to Wireless routers separated from the modem

A modem with separate wireless router

This is a third option to share internet connection at home, a combination of DSL / Cable modem and the wireless router. The manufactures introduce wide variety of wireless router products you can select at the marketplace today. If you have already had a DSL or Cable modem at home,you can purchase a wireless router with 802.11g standard or the future wireless technology draft 802.11n standard.

If you are building a network from scratch to share internet connection, it is strongly recommended to consider the benefits of draft 802.11n. It allows existing 802.11 wireless G and B users to continue to use the network, while providing a significant speed boost for 802.11n users.

Pros

More secure network with advanced security features and services such as dual-firewall features, DHCP server, VPN-tunneling pass-through, secure wireless connection with the strongest encryption.
Separate device between modem and wireless router, preventing a single point of failure

Cons

Purchasing separate modem and router is costly more money
Need a better networking knowledge

How to Secure a Wireless Network

2011-06-24T09:16:00.000-07:00

One of the advantages of the wireless networks is apparent - no wires to allow you connect to the network without the hassle of running a network cable.You can surf the internet with your laptop by your pool side or with your iPad at the gazebo. You can go live games in the comfort of your living room without the clutter of the wires. Unlike wired LAN, the wireless connection is prone to the eavesdropping by users within the network coverage.

How to secure a wireless network?

Security might be the last thing in your mind when you build a wireless network in home or offices. You can easily secure your wired connection by physically protecting the system cabling not to easily be injected by the intruders. But with wireless network, unauthorized users can easily pick the signal as far as 300 meters or even more by using hi-gain directional antenna with laptop. Therefore you must know how to secure a wireless network not ot easily be hijacked by the intruders.

It's easier to crack the wireless connection than wired connection because you don't need to physically connect to the network. Therefore you can access it easily because the data transfer occurs over the airwaves. there are three areas you can pay attention to in securing a wireless network:

Securing the wireless connection using the strongest industrial wireless encryption available today
Securing the endpoint of the network that faces internet
And create a security boundary for your guests

Securing a wireless connection

Currently there are two main wireless security encryption you can implement for securing your wireless connection. If you have many wireless clients that are powered by the legacy wireless 802.11b/g, you can secure the connection using the WEP (Wireless Equivalent Privacy). Both end of routers/ APs and the wireless clients must use the same security settings.

If your wireless routers / APs are powered by the latest wireless 802.11n standards, and your wireless clients use the same wireless n standards, they can support the latest wireless encryption Wi-Fi Protected Access (WPA/WPA2).Always use this strongest wireless security encryption in connecting to the network it possible.

How to secure a wireless network using WPA/WPA2 encryption? mostly wireless devices that support the WPA/WPA2 encryption include the WPA (Wi-Fi Protected Setup) feature to let you connect the secure network network by just pressing the WPS button. Unless, you need to configure it manually. Consult the device manual book regarding the security configuration using the WPA/WPA2.

In Windows you have an easy way to connect to the secure network the Windows connect Now (WCN). You can configure the computers using the WCN with the following steps:

Using the UTP network cable that came with your wireless router, temporarily connect your computer to one of the Switch LAN ports on your wireless router.
Turn your computer on; it will automatically connect to your router.
Open the Internet browser and type in the address to configure your router, as described in your router's instruction manual. The following table lists known wireless router default address, username and password as your reference.

Router	Address	Username	Password
Belkin	http://192.168.2.1	Logon prompt	(leave blank)
D-Link	http://192.168.0.1	admin	(leave blank)
Linksys	http://192.168.1.1	admin	admin
NETGEAR	http://192.168.0.1	admin	password
TRENDNET	http://192.168.10.1	Admin	admin

Type in the appropriate username and password to logon to the router.
The browser will show your router's configuration page. Find the wireless security page to select the wireless security modes available. Wireless routers /AP support six wireless security modes : WPA Personal, WPA Enterprise, WPA2 Personal, WPA2 Enterprise, RADIUS, and WEP.

If your router supports Windows Connect Now, you can quickly and easily configure the router by following the instructions in Using Windows Connect Now technology.

If you are using WPA, always remember that each device in your wireless network MUST use the same WPA method and shared key, or else the network will not function properly.

MAC Address filter

Wireless access can be filtered by using the MAC addresses of the wireless devices transmitting within your network's radius. Select Enabled/disabled the wireless MAC filter in the router's configure the wireless MAC filter either prevent or permit access.

You should know the MAC addresses of the wireless devices to be included in the permit or prevent MAC address record. The MAC address on wireless on wireless network adapters is typically printed on the network adapter's underside.

But if your Wi-Fi adapters have been installed in the desktop PCI slot, you cannot recognize the physical address visually. In a command line prompt (press Windows + R keys simultaneously and type in CMD and press enter) type ipconfig/all command and you can find the device physical address.

change the default wireless network name or SSID

Wireless devices have a default wireless network name or Service set Identifier (SSID) set by the factory. This is the name of your wireless network, and can be up to 32 characters in length. Each wireless product has their own default SSID as the default wireless network name. You should change the wireless network name to something unique to distinguish your wireless network from other wireless networks that may exist around you, but do not use personal information because this information may be available for anyone to see when browsing for wireless networks.

Change the default password

Wireless routers /Ap have a default username and password set by the factory. See the above table. Mostly have their default username is admin or some have their default password as password. Hackers know these defaults and may try to use them to access your wireless device and change your network settings. To thwart any unauthorized changes, customize the device's password so it will be hard to guess.

Securing the end point of the network facing the internet

How to secure a wireless network from any types of internet threats? In depends on the wireless routers security features, but typically all the wireless routers support dual firewall features:NAT and SPI which is enabled by default. NAT helps you to hide the private network from the public network, and the stateful packet inspection will examine the incoming packets thoroughly for any false positive packets.

Create a security boundary for the quests

Many wireless routers today support the Guest Network feature - a feature that allows you create multiple SSIDs. You can create separate Guest network with different password and with limited access right not to allow the guest gain access rights to your local private network. Typically the guests are granted an internet access only. This is a secure way to provide public internet access without compromising system security.

DHCP Server

2011-06-24T02:53:00.000-07:00

In networking infrastructure, DHCP server is very essential services to provide IP configuration automatically to hosts including the computers on the network. With the proper IP configuration to the hosts on the network, all the hosts can communicate each other.

Deploying the IP address manually to hundreds of computers on the network is prone to the IP addresses conflict due to miss-typing - a normal human error. DHCP server is designed to help the network administrator to reduce the complexity of administrating the IP address configurations. By issues leases from a central database, DHCP server automatically manages address assignment and configure other essential settings for your network clients.

In windows networking, when the DHCP server is not available, the clients will adopt the alternate configuration or APIPA (Automatic Private IP Addressing) The range of APIPA addressing is between 169.254.0.0 until 169.254.255.254. If the computer in the network (with DHCP server available) receives the IP address in the APIPA range, it indicates that the computer is not connected or there is connectivity problem. See also wireless network troubleshooting.

Network administrator should configure the IP address or the pool of the IP address that will assigned to the computers in the network. In Windows system, the clients lease addresses for a specific length of time from the DHCP server. Once 50% of the lease has expired, the clients will attempt to renew the same IP address. The DHCP server will renew addresses for another lease period.

DHCP server Scopes

A DHCP scope is a pool of IP addresses within a logical subnet, for example 192.168.1.1 through 192.168.1.220 that the DHCP server to manage distribution and assignment of IP addresses and of any releated configuration parameters (such as DNS, gateway) to clients on the network. Once DHCP scope is for one DHCP server can serve multiple subnets.

DHCP server scope specifies the range of addresses available for lease. An IP address within a defined scope that is offered to a DHCP client is known as a lease. Each lease has a specified duration, and the clients must periodically renew the lease.

An exclusion range can be set within the range of defined scope if you don't want to lease to DHCP clients. Exclusion range assures that the DHCP server does not offer the exclusion range to DHCP clients. You can also provide reserve addresses for specific clients with MAC addresses which are typically used for servers, printers and other network devices that require static IP addresses.

How the process of DHCP server to the clients?

DHCP clients broadcast DHCPDISCOVER packet to the network
DHCP server then responds with DHCPOFFER packet
DHCP clients broadcast DHCPREQUEST packet
DHCP server responds with DHCPACK packet
After 50% lease time, DHCP clients will attempt to renew address with a DHCPREQUEST directed to the DHCP server
DHCP server responds with DHCPACK adain

Configuring the Client

To configure a client to receive its IP address information from a DHCP server, the TCP/IP configuration of the computers must be configured to "obtain an IP address automatically" options. To configure the client to receive DNS options from the DHCP server, you should select the "obtain DNS server Address Automatically" option.

DHCP servers use private IP address instead of IP addresses ( registered IP address), since private IP addresses are not rout ableto the Internet, thus with the dual firewall features of the firewall will help you reduce network security threats from the Internet.

How to Configure DHCP server in Wireless Routers

Mostly all the wireless routers including the routers with build-in DSL modem or routers with build-in cable modem are powered by the DHCP server which enabled by default. So anyone that knows nothing about DHCP server, no worries - just leave the default setting.

Open the router configuration menu from the web-based utility by typing the default IP address of the wireless routers for example http://192.168.1.1 (For linksys) and press enter. The login dialog prompts you to type in the user-name and password of the router. The following table shows some wireless routers with their default IP address, user-name and password.

Router	Address	Username	Password
Belkin	http://192.168.2.1	Login	(leave blank)
D-Link	http://192.168.0.1	admin	(leave blank)
Linksys	http://192.168.1.1	admin	admin
NETGEAR	http://192.168.0.1	admin	password
TRENDnet	http://192.168.10.1	admin	admin

Find the configuration menu with relates to DHCP menu or similar one (refer to manual book of the router). DHCP Server is enabled by factory default.If you already have a DHCP server on your network, or you don't want a DHCP server, then select disabled.

Starting IP address: Enter a value for the DHCP server to start with when issuing IP addresses. Assume the Router's default IP address is 192.168.1.1, the starting IP Address must be 192.168.1.2 or greater, but smaller than 192.168.1.253.

Maximum number of DHCP Users: Enter the Maximum number of PCs that you want the DHCP server to assign IP addresses to. This number cannot be greater than 253. The default is 50.

Client Lease Time: The Client Lease Time is the amount of time a network users will be allowed connection to the router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be "leased" this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address. The default is 0 minutes, which means one day.

Static DNS(1-3): The Domain Name System (DNS) is name resolution which is used to translate the names into their corresponding IP address. The DNS server is typically provided by the ISP where you subscribe the internet is.

WINS: The Windows Internet Naming Service (WINS) manages each PC's interaction with the Internet. If you use a WINS server, enter that server's IP Address here.Otherwise, leave this blank.

DHCP Reservation: Click DHCP Reservation if you want to assign a fixed local IP address to a MAC address. You will see a list of DHCP clients with the following information: Client name, Interface, IP address, and MAC address. Click the select checkbox to reserve a client's IP address. Then click Add Clients.

If you want to manually assign an IP address, enter the client's name in the Enter Client Name field. Enter the IP address you want it to have in the assign IP Address field.Make sure the IP address is between the starting DHCP server's IP address and maximum number of DHCP users range. Enter its MAC Address in the To This MAC Address field. Click Add.

How to Build a Wireless Home Network - Tutorial

2011-06-23T10:21:00.000-07:00

This tutorial will guide you through the process of planning, building, and testing a wireless home network. Although mainstream wireless networking has made amazing strides in the past few years, wireless technology and terminology remains a bit difficult for most of us to comprehend. This same guide will help small business networks, too!

Build a Wireless LAN, Step by Step

You can build any typical wireless home network, a Wireless LAN (WLAN), using this simple three- step approach:

Identity the WLAN design that's best for your situation
choose good wireless gear
Install gear and test the configured WLAN

In subsequent pages, I break down each of these steps in more detail.

Ready to Go Wireless?

This article assumes you've already made an informed decision to go wireless rather than build a traditional cabled network. Though prices have dropped dramatically from a few years ago, when wireless gear was quite expensive, wireless networks still aren't for everyone 9yet). Unsure that wireless will ready meet your needs? Use the following supplementary articles to help you choose wisely:

Benefits of Wireless

Wireless offers tangible benefits over traditional wired networking. Ever tried to quickly look up a recipe on the Net while cooking in the kitchen? Do the kids need a networked computer in their bedroom for school projects? Have you dreamed of sending email, instant messaging, or playing games while relaxing on your outdoor patio? These are just some of the things can do for you:

Next Stop - Terminology

The field of computer networking once sat squarely in the domain of techies. Equipment manufacturers, service providers, and "experts" that study the field of networking tend to go quite heavy on technical jargon. The wireless networking industry is gradually improving home. But there is still much work for the industry to do. Let's take a quick look at the common jargon of wireless home networking and what it all means.

When researching wireless equipment to buy, or talking about wireless networking with friends and family, you should have a solid understanding of this terminology.

What is a WLAN?

We've already said that a WLAN is a "typical" wireless home network. That's because a WLAN is a wireless LAN, and a LAN is a related group of networked computers situated in close physical proximity to each other. LAN's can be found in many homes, schools, and businesses. Though it's technically possible to have more than one LAN in your home, few do this in practice. In this tutorial, we explain how to build a single standard WLAN for your home.

What is Wi-Fi?

Wi-Fi is an industry name used to market wireless networking products. You'll find a black-and-white Wi-Fi logo or certification emblem on virtually any new wireless equipment you buy. Technically speaking, Wi-Fi signifies conformance to the 802.11 family of wireless communication standards. But because all mainstream wireless home network gear users the 802.11 standards today, basically the term "Wi-Fi" merely distinguishes wireless equipment from other network gear.

What is 802.11a/802.11b/802.11g?

802.11a, 802.11b, and 802.11g represent three popular wireless communication standards. Wireless networks can be built using any of the three, but 802.11a is less compatible with the others and tends to be a more expensive option implemented only by larger businesses. Use the supplemental article below to help you pick 802.11 standards for your wireless LAN.

What are WEP and Wardriving?

The security of wireless home and small business networks remains a concern for many. Just like we use radio or television receivers to tune into station broadcasts, it's almost as easy to pick up signals from a nearby wireless home network. sure, credit card transactions on the web may be secure, nut imagine your neighbors spying on every email and instant message you send!

A few years ago, some techies popularized the practice of wardriving to raise awareness of this vulnerability in WLANs. With the help of cheap, home-made equipment, "wardrivers" walked or motored through neighborhoods snooping the wireless network traffic emanating from nearby homes. Some wardrivers even logged their computers resources and Internet access.

WEP is an important feature of wireless networks designed to improve security. WEP scrambles network traffic mathematically so that other computers cab understand it, but humans cannot read it. WEP helps protect your WLAN from wardriving and nosy neighbors, and today, all popular wireless equipment supports it. Because WEP is a feature that can be turned "on" or "off", you'll simply need to ensure it is configured properly when setting up your network.

Types of Wireless equipment

The five types of equipment found in wireless home networks are:

wireless network adapters
wireless access points
wireless routers
add-on wireless antennas
wireless signal boosters

some of this equipment is optional depending on your home network configuration.

How Does Automatic Wireless Network Configuration Work?

2011-06-22T20:54:00.000-07:00

By default, windows xp attempts to connect to wireless networks in the following order:

Available networks that are in the preferred network list ( in order of listing)
Preferred networks not in the Available list( in order to listing)
Other networks depending on Advanced settings chosen

In Windows XP with Service pack 2 (SP2), each network (even Preferred networks) can be configured individually to bypass automatic configuration. To enable or Disable automatic configuration on a per- network basis, respectively check or unchecked the "connect When this network is within range" check box within that network's Connection properties.

Wireless XP periodically checks for new available networks. If it finds a new network listed higher in the Preferred set that is enabled for auto configuration, Windows xp will automatically disconnect you from the lesser-preferred network and re-connect you to the more preferred one.

Advanced Automatic Wireless Configuration

By default, windows xp enables its automatic wireless configuration support. Many people mistakenly assume this means your laptop will automatically to any wireless network it finds. That is untrue. By default, windows xp only auto-connects to Preferred networks.

The Advanced button on the Wireless Networks tab of wireless Network Connection properties controls the default behavior of windows xp automatic connections. One option on the Advanced window, " Automatically connect to non-preferred networks", allows windows xp to auto-connect to any network on the Available list, not just Preferred ones. This option is disabled by default.

Is Automatic Wireless Network Configuration Safe to use?

Yes! The Windows xp wireless network configuration system limits automatic connections by default to Preferred networks. Windows xp will not automatically connect to non-Preferred networks such as public hotspots, for example, unless you specifically configure it to do so. You can also enable / disable auto- connection support for individual Preferred network as described earlier.

In summary, the automatic wireless Internet / network connection feature of windows xp allows you to roam between Wi-fi networks at home, school, work or public place with a minimum of hassle and worry.

Automatic Wireless Network Connections in Windows XP

2011-06-22T20:20:00.000-07:00

windows xp (either professional or home Edition ) allows you to establish a wireless network connection to Wi-Fi network routers and access points automatically. This feature helps you to make wireless Internet / WiFi network connections more easily with laptop computers and is highly recommended for those who roam between multiple locations.

Does My Computer Support Automatic Wireless Network Configuration?

Not all windows XP computers with wi-fi wireless support are capable of automatic wireless configuration. To verify your windows xp computer supports this feature, you must access its wireless Network Connection Properties:

From the Start Menu, open Windows Control Panel.
Inside Control Panel, Click the "Network Connections" option if it exists, otherwise first click "Network and Internet Connections" and then click "Network Connections".
Finally, right click "wireless Network Connection" and choose "Properties".

In the Wireless Network Connection properties window, do you see a "wireless Networks" tab? If not, your Wi-Fi network adapter lacks so -called windows Zero Configuration feature will remain unavailable to you. Replace your wireless network adapter if necessary to enable this feature.

If you see a "Wireless Networks " tab, click it , and then click the "view wireless Networks" button appearing on that page. A message may appear on the screen as follows:

"Windows cannot configure this wireless connection. If you have enabled another program to configure this wireless connection, use that software....".

This message appears when your wireless network adapter was installed with a software configuration utility separate from windows xp. The windows xp automatic configuration feature cannot be used in this situation unless the adapter's own configuration utility is disabled, which is generally not advisable.

Enable and Disable Automatic Wireless Network Configuration

To enable automatic configuration, ensure the "Use Windows to configure my wireless network settings " check box is checked on the wireless Networks tab of the Wireless Network Connection Properties window. Automatic wireless Internet / Wi-Fi network configuration will be disabled if this checkbox is unchecked. You must be logged on with windows XP administrative privileges to enable / disable this feature.

What Are Available Networks?

The Wireless Networks tab allows you to access the set of "Available" networks.Available networks represent those active networks currently detected by windows xp.Some Wi-Fi networks may be active and in range but not appear under Available networks. This occurs when a wireless router or access point has SSID broadcast disabled.

Whenever your network adapter detects newly available Wi-F- networks, you will see an alert in the lower- right corner of the screen allowing you to take action if necessary.

What Are Preferred Networks?

In the wireless Network tab, you can build a set of so-called "preferred" networks when automatic wireless configuration is active. This list represents a set of known Wi-Fi routers or access point you wish to automatically connect to in feature. You can "Add" new networks to this list by specifying the network name (SSID) and appropriate security settings of each.

The order Preferred networks are listed here determines the order that Windows XP will automatically attempt when seeking to make a wireless / Internet connection. You can set this order to our preference, with the limitation that infrastructure mode networks must appear ahead of all ad hoc mode networks in the Preferred list.

TEW-692GR 450Mbps Simultaneous Dual Band Router

2011-06-22T09:03:00.000-07:00

Trendnet launches TEW-692GR the fastest dual band wireless router delivering the high speeds up to 450Mbps each band concurrently

i was wondering why Trendnet didn't introduce wireless N750 dual band router, the router with concurrent dual bands delivering the high speed up to 450Mbps in 5GHz band and up to 300Mbps in 2.4 GHz band like it's competitors Linksys, Netgear and Belkin. Finally I realize that Trendnet would like to be the fastest router delivering the high speed up to 450Mbps each band concurrently. It's not a wireless N750 but the first wireless N900 router.

Linksys launches the new E4200 N750 router in January 2011 and shipped the router before Netgear did its WNDR4000 N750 router into the market. Around April 2011, Belkin also shipped its new generation Belkin N750 DB router. After being showcased in concurrently in jan 2011.

What this Product Does

The Tew-692GR is the first router with the speeds up to 450Mbps in each band concurrently. Many of you are familiar with the N300,N450, N600 and N750 routers, but this one should be the first N900(450Mbps+450Mbps) routers in the market.

Like other new generation of wireless routers, the TEW-692GR supports Wireless Protected Setup (WPS) to help you connect the clients (with WPS enable) to the network by just pressing a button. It supports the strongest wireless security encryption up to WPA2-Radius.

Like other high performance wireless routers, the TEW-692GR includes gigabit Ethernet ports for LAN (4x) and WAN (1x) interfaces for fast wired speed. You can utilize the gigabit Ethernet ports to connect to your computers with Gigabit NIC ready for optimum data throughput.

Multiple Guest Networks

This is interesting , the TEW-692GR supports up to four (4) virtual networks (SSID) each bands for totally eight SSIDs it can support. We know that Netgear supports guest network each band for totally four SSIDs. Linksys and Belkin supports up to 3 SSIDs.

Unfortunately, the router doesn't support USB port for shared storage or shared printer. Like its competitor Linksys E4200 and WNDR4000 that support the shared storage with built-in media server, with the absence of USB shared storage you need to manage the storage differently. This is the disadvantage side of this router so far.

Top 5 Wireless routers- best selelrs in Amazon in networking - router category - most popular wireless N routers with five star average ratings

with a bunch of wireless routers available in the market today, it is obviously confusing the way you choose which one is the best for your need. Wireless router is the heart of your home wireless network to share the internet connection and other networking tasks. Unlike wired network which the connectivity performs well with least interference, wireless network is prone to any types of signal attenuators within its network coverage. Any sources of signal attenuators (including 2.4 GHz-based wireless home appliances, concrete walls, file cabinets etc) can degrade the performance of your wireless connection significantly.

Wireless router manufacturers introduce their new new router products powered by the latest wireless 802.11n technology, dual band support and embedded with gigabit interfaces for both LAN and WAN Ethernet ports delivering high speeds of up to 300Mbps or even faster up to 450Mbps. But remember, the speed specification are in ideal conditions. In the real world, you never reach those speeds due to many factors and environment conditions. Unlike wired connection, the wireless network is prone to any type of signal attenuator sources that can causes the wireless connectivity issues. Moreover, wireless network shares the bandwidth. The more wireless clients connect to the network, the more traffic shares the bandwidth that makes each connection getting slower. So if you are planning to purchase a wireless router, listen from others who have experiences with the products and read what their opinion about the products.

Without including the legacy wireless routers, the following top 5 wireless routers are currently become the best seller in Amazon in networking - router category.

1. MediaLink Wireless N150 Router

You will be surprised if you read the customers reviews about this router. Nearly 90% out of the customer reviews give averagely 5 star ratings for easiness of the installation, value for money, attractiveness, and technical support.

Wireless Troubleshooting

2011-06-21T10:41:00.000-07:00

Building a wireless network at home is quite easy particularly when you use the all-in-one modem router devices that function as modem, router, wireless access point and the switch. Technically you just need to connect the cable/ DSL modem port to the Cable / DSL line and one phone call to the ISP where you sign-up the Internet services, then your wireless network should go live. But sometimes it is not that simple, wireless network problem occasionally happen. Fortunately, you can usually do the wireless troubleshooting and solve here problems yourself.

Wireless troubleshooting in most cases is a matter of going through a series of steps to eliminate potential issues one by one before you finally find the problem as general includes three general steps, isolating your problem, troubleshooting the problem, and ,if necessary , contracting the right organization fpr support.

Isolating Networking Problem

Before you do the wireless troubleshooting, you need to localize or isolate what the underlying of the wireless network problem is. A typical home networking includes three layers - the internet, the modem / router, and the computers on your network. These three layers can be described as shown in the following figure.

you must first identify which network layer is causing the problem, before you can effectively troubleshoot a problem.

Although you can fix most problems yourself, knowing which layer is causing

the network or wireless network problem will help you contract the right organization for support only if you can't fix the problem yourself.

Follow the steps below to identify which layer is causing the problem:

Click Start ==> Control Panel ==> Click Network and Internet Connections
Under Network and Internet connection ==> Click Network Connection
Now you can examine the status of your network adapter under this Network Connections window with the following possibilities:

A> Connected status but cannot access the internet

Have a look at this status that applies both to the wired adapter and Wireless adapter.


Local Area connection connected status

Wired or Wireless network problem with this symptom indicates that the computer is properly connected to the modem and router, or if you are using the wireless adapter your computer is connected properly to the wireless network. There must be an internet problem.

Wired /Wireless troubleshooting this kind of wired / wireless network problem can be done by following the steps below.

Verify if you can't connect to the internet by opening your browser and attempt to connect some websites such as xp-twiks.blogspot.com or whatever. If you can find that some websites open successfully but certain websites fail, then you have no wired or wireless network problem. If you cannot open all the websites, then follow the next step.
Unplug the modem and wait a minute, then plug it back again.
Unplug the wireless router to the modem, if you have separate modem and wireless router. Wait a minute and then plug your modem back in again.
Restart the computer. Try again with some websites and see if it is successful. If it is successful but the connection is significantly slow while the other computers ( if there are some computers on the network), you can suspect that there are some computers consulting too much of your Internet bandwidth or attempting to connect to too many computers. For your wireless troubleshooting, close the applications, or configure it to use less bandwidth or fewer connections or shutdown all other computers and make a test again as in step 1.
If you have separate modem and wireless router, disconnect the wireless router and connect the computer directly to the modem. Restart the computer. if the computer is now connecting to the internet successfully, you have problem with the wireless router.
If this last step is still no luck, then your modem is problem or your ISP is in problem.contact the ISP for support.

B> The NIC or the wireless adapter is disabled


disable state connection

Wired or wireless network problem with this symptom is due to the NIC / wireless adapter in disable status. There must be someone or probably you have manually disabled the network adapter. You need to enable the adapter to fix it by right clicking the icon and select the Enable.

C> limited or no connectivity

Limited Connectivity Status

This indicates limited or no connectivity. This is basically no problem with the computer, connection to the router - modem or wireless network is OK but the router is configured incorrectly, or there is a problem between your modem and the internet.

Limited or No Connectivity problem could be due to different problems, including a failed Internet connection, the router or the adapter is not configured correctly. Follow the steps below for wireless troubleshooting.

Right click the adapter in the network Connections window, and then click Repair.
Unplug your modem and wait a minute, and then plug your modem back in again.
If you have a router connected to your modem, unplug it and wait a minute, and then plug the router back in again.
Restart the computer.
Up to this steps your adapter still shows "Limited or No Connectivity" ,make sure that the router has DHCP server feature enables. DHCP server provides the IP address automatically to the computer clients on the network. Restart the computer.
If the modem and the wireless router are two separate devices, disconnect between the modem and the router and connect the computer directly to the modem. Restart the computer and see if it fixes the problem.
If still no luck, connect your ISP for support. The "Limited or No Connectivity" error message indicates that your computer is properly connected to your home network; however, the ISP's DHCP server is not assigning it an IP address. This problem could be caused by a failer DHCP server on the ISP's network, a failed modem, or a problem with your Internet connection. Probably the ISP will provide a static IP address for you.

D>The Cable is Unplugged


Cable Unplugged Status

This indicates that the cable is Unplugged, no connection to your modem or router.

Check the network cable if it is unplugged.
If the network cable is properly plugged into the port, try to swap into different port of the modem-router. Check the light indicator in the modem or router and see if the light is blinking on the corresponding port when you swap the cable to the port.
If still no luck, replace the network cable with the good one.
If still no luck, while the other computers that connect to the same modem / router are fine, then your computer NIC adapter is faulty. Replace the NIC adapter.

E> Wireless adapter cannot connect to the wireless network

No Connection to the wireless network

This indicates that the computer cannot connect to the wireless network. There are two reasons that the adapter cannot connect to the wireless network, unable to make successful wireless connection or intermittent connectivity.

802.11 WLAN

2011-06-21T08:41:00.000-07:00

802.11 WLAN (Wireless Local Area Network) allows people to communicate without any networking cables. However, Wireless devices on this Wireless LAN Networking need to communicate with the networking devices on the "wired LANs".

802.11 WLAN standards include 802.11b, 802.11g(both operate in 2.4 GHz band), and the draft 2.0 802.11n standards. Draft 2.0 802.11n is not ratified yet,but mostly the wireless manufactures have shipped their lines of products using this draft version.

Unlike wired networks, 802.11 WLAN offers some benefits that are apparent - " no wires" and some that you might not have considered. The most obvious is portability with Wireless LAN Networking, you can surf the Internet by your pool side, your fireplace, or anywhere else in your house with your laptop. Or you can play online game with your XBOX console in the comfort of your living room without the clutter of the wires.

802.11 WLAN Terms and concepts

Access point

An Access point in 802.11 WLAN is a device that typically servers as a bridge or gateway between wireless devices and the devices on a cabled network. An Access Point must be able to receive and forward network traffic between wireless and cables network devices. Multiple Access Points can act as repeaters to extend the range of a wireless LANs networking. connecting via an access point is called wireless Infrastructure Mode. On Apple networks, this is called Airport Network Mode.

The following figure shows a typical 802.11 WLAN daigram deployed in business or enterprise networks. The topology is a wireless LAN networking infrastructure.

Since the Wireless LAN networking becomes so popular today, wireless manufacturers ship the wireless home routers to support the wireless home networking. The following figure shows typical 802.11 WLAN deployed in home or SOHO(small office home office) which includes a cable modem ( such as Surfboard cable modem ) or xDSL modem, and a wireless access point. While the computers that connect to the Wireless LAN networking need other wireless network adapters such as wireless USB network adapter or wireless PCI adapter ( for desktop computers).

The figure below shows a typical wireless access point configured as the repeater 802.11 WLAN infrastructure. There are many wireless access points (such as DAP-2590 Air-premier, or DAP-3520 Air premier access point ) that can operate as the repeaters in a point-to-multi point Wireless LAN networking infrastructure.

Ad Hoc (peer-to-peer) mode

802.11 WLAN in Ad-Hoc mode (peer-to-peer mode) is a wireless LAN network topology where devices communicate with each other directly. An access point is not used. On Apple networks, Ad Hoc mode is called computer-to-computer mode. Ad Hoc mode is not as reliable as Infrastructure mode, and if used, should be limited to six devices or less.

In the figure below shows simple as-hoc diagram of two laptops ( with notebook wireless adapters) connect to the printer-server to print wirelessly.

Note: The term "peer-to-peer" in 802.11 WLAN might have a different meaning depending on its usage. While Ad Hoc peer-to-peer mode refers to a wireless network topology, print-server peer-to-peer printing refers to a direct print from a network computers to a printer. Commonly all the print-servers can be deployed in both Ad-Hoc Wireless LAN networking or in infrastructure wireless topology.

Channels

IEEE standards for 802.11 WLAN networks specify a spectrum of radio waves for wireless LAN networking communications. The allowed spectrum is divided into channels consisting of 22 MHz each. The number of available channels authorized for use may be restricted based on your location. Typically all the wireless adapters which are configured for infrastructure mode, they will automatically adjust their channel to match the wireless access point.

Encryption

Wireless LAN networking use radio signals for networking communications, which can be easily monitored by someone eavesdropping on the network. To deter eavesdropping and to help ensure data privacy, encryption of wireless communications may be used.The latest industrial standards in wireless security is the Wi-Fi Protected Access (WPA/WPA2).

Signal range

In the 802.11 WLAN, the range over which wireless devices can communicated depends on the physical environment and the orientation of the wireless access point. For typical 802.11g standard, the wireless coverage ideally can range up to 300 feet. With the wireless -N standards and enhanced technology such as MIMO antenna technology, the wireless coverage can be 4x as long as the 802.11g standards.

SBG6580 CABLE MODEM WIRELESS ROUTER

2011-06-20T03:43:00.000-07:00

mplementing a wireless network in homes or small offices becomes the busiest tasks today among other networking tasks. This is due to the abundance of affordable wireless router and access points available in market today. Wireless networks have apparent benefit - no wires , no hassle a running a network cable to build the infrastructure as opposed to wired network. The easiest method to build a wireless network in home, if you subscribe a cable services, is to install the Surfboard SBG6580 cable modem wireless router.

The surfboard SBG6580 cable modem wireless router is an all- in - one device that includes all the requirements to build a wireless network in home or small offices. To build a wireless network, you require a modem (cable or ADSL), a router / firewall, a switch and a wireless access point.A router / firewall is used mainly for network protection against any threat and help you share a single internet connection, a wireless access point is used to extend the wired network without the wires. The Surfboard SBG6580 integrates the routerd, the DOCSIS 3.0 cable modem and the wireless N access point into a single device, the all-in-one device for all your wireless networking environments.

Cable Modem Function

The surfboard SBG6580 is a DOCSIS 3.0 / EuroDOCSIS 3.0 cable modem a new generation of the DOCSIS / EuroDOCSIS infrastructure which enables channel bonding of up to 8 downstream channels. This allows the service providers to offer their customers advanced multimedia services delivering the high speeds of up to 300Mbps in DOCSIS and up to 400Mbps in EuroDOCSIS for downstream and up to 100Mbps for upstream.

Firewall / Router Function

Like other wireless routers, the Surfboard SBG6580 cable modem wireless router supports dual firewall feature(NAT and SPI). Network Address Translation (NAT) helps the private network hide from the public network and allow you share a single broadband internet connection with many computers in the network. Stateful Packet Inspection (SPI) filter the incoming traffic from the internet more through deep into the packet for false positive packets.

The router includes the DoS (Denial of Services) and malware protection. The modem also supports the routing function including static route and dynamic routing (RIPv1, RIPv2). This is the second requirement for your network.

High Speeds

The Surfboard SBG6580 cable modem wireless router is powered by the latest wireless 802.11n technology with dual band support. Unfortunately it is a selectable dual band, not simultaneous. It means that the router will operate in single band in a time either in 2.4GHz or 5GHz band. If you have mix wireless devices with different operating bands. If you except the router to accommodate all the devices for example your iPad, 5GHz-based XBOX adapter, your notebook with 2.4GHz wi-fi adapter and other smart-phones, you'll be sorry. The modem can only work in single band either in 2.4GHz (for your smart-band) band. If you have uniform wireless adapters that supports 5GHz band, that'll be great for maximum data throughput.

The modem includes 4xGigabit Ethernet ports to let you connect up to computers with 10/100/1000 Ethernet ports. Brand new computers today are equipped with gigabit Ethernet ports you can connect to the routers using the Cat5e UTP cable for reliable wired connections.

To provide the IP address configuration automatically, the modem inccludes a DHCP server that will provide IP address leases to the clients on the network. This will help you reduce the administrator overhead.

Security

Wireless connections is prone to the eavesdropping by the users within the network coverage.Therefor you need to encrypt the connection by the industrial wireless security WPA/WPA2 (Wireless Protected Access). The Surfboard SBG6580 cable modem wireless router supports wide range of security including WEP-64/128, WPA-PSK, WPA, WPA2, TKIP,AES,802.1x, 802.11i (pre-authentication). For secure client connection to the network, the device supports user-friendly WI-FI protected setup (WPA) to easily connect with WPS compatible device.

INtroduction to network File sharing

2011-06-13T09:40:00.000-07:00

Computer network allows you to share files with friends, family, coworkers and customers. Before the Internet and home networks became popular, files were often shared using floppy disks. Nowadays , some people still use CD-ROM/DVD-ROM disks and USB keys for transferring their photos and videos, but networks give you more flexible options.

Network file sharing is the process of copying files from one computer to another using a live network connection. This article describes the different methods and networking technologies available to help you share files.

File Sharing with Microsoft windows

Microsoft windows (and other personal computer operating systems) contain built-in features for file sharing. For example, Windows file folders can be shared across a local area network (LAN) or the Internet using the Explorer interface and network drive mappings, You can also setup security access restrictions that control who can obtain the shared files.

FTP File Transfers

File Transfer Protocol (FTP) is an older but still popular method to share files on the Internet. A central computer called the FTP server holds all the files to be shared, while remote computers running FTP client software can log in to the server to obtain copies.

All modern computer systems contain built-in FTP client software, and popular Web browsers like Internet Explorer can also be configured to run as FTP clients. Alternative FTP client programs are also available for free download on the Internet. As with windows file sharing, security access option can be set on the FTP server requiring clients to supply a valid username and password.

New cisco Router supports 322Tbps, Designed for Internet video

2011-05-23T21:03:00.000-07:00

what can you do with 322Tbps? Cisco systems says it's enough bandwidth to allow every person in china to make video call - simultaneously. And if that's something you want to do, Cisco says it now has hardware capable of task.

The company's newest large-scale core router, the CRS-3, is capable of handling such a speed, which Cisco said is 12 times as fast as its closest competitor and the three times the speed of its predecessor. it has invested $1.6 billions in the product's design and engendering.

The CRS-3, is the product that Cisco last month said would " forever change the internet and its impact on consumers ,businesses and governments."

CRS stands for "Carrier Routing System" a reference to the devices use by large telecom provider.

Tbps stands for terabits-per-seconds and a terabit is a trillion bits. compare that to the megabits-per-second that today's highest speed business and consumer broadband connection are measured in.

LAN - Local Area Network

2011-05-11T07:48:00.000-07:00

Definition:-A Local Area Network (LAN) supplies networking capability to a group of computers in close proximity to each other such as in an office building, a school , or a home. A LAN is useful for sharing resources like files, printers, games or other applications.A LAN is turn often connects to other LANs, and to the Internet or other WAN.

Most LANs connect workstations and personal computers. Each node (individual computers) in a LAN has its own CPU with which it executes programs, but it also is able to access data and devices anywhere on the LAN. This means that many users can share expensive devices., such as laser printer as well as data.Users can also use the LAN to communicate to each other, by sending email or engaging chat sessions.

What are the first step needed when your system is attacked by virus

2010-08-02T21:52:00.000-07:00

I am going to share about the first important steps to prevent the system, when the system is attacked by virus. (these steps also helps to improve your system performance and speed).

1) Go to task manager (by pressing CTRL + ALT + DEL).

2) Go to process tab.

3) Now you have to find the unwanted.exe files and end process that.

some tips to find these unwanted.exe process

* Find the .exe process runs under your username (but not as system / local

services /network service).

* then ignore the process such as explorer.exe, antivirus process(for example if

you install avg it runs as avgtray,wuauclt), applications name.

* Then endprocess all other unwanted.exe process for example: regsvr.exe,

autorun.inf, etc..

4) Now go to start-->search then search for .exe, .inf files in your computer and delete the unwanted files.

(Note : These are the manual steps to delete the virus. My suggestion is install any antivirus such as avg,avast,Bit defender and update that frequently).

1) All computers need basic software known as an Operating system to function.
2) The OS acts as an interface between the user, application programs, hardware, and system peripherals.
3) operating systems can be of two types: Network operating system and simple stand alone desktop.
4) DOS provides a text based interface called the command prompt that can be issued to perform file and disk management, and execute programs.
5) The DOS commands like COPY, MOVE, XCOPY, REN, DEL, MD, RD etc. are used for file management.
