HOW TO GET ONE MERCHANT FOREX THOUSANDS OF DOLLARS PROFIT WITHIN A FEW HOURS ONLY THROUGH THE INTERNET

Profit in the Forex trading on the last digit changesonce the value of a currency combination. The movement of these figures is called PIP.For example, say you want to trade EUR / USD currency. Selling price is1.2035. Suppose the price rose to 1.2065 in 30 minutes. Thenyou will make a profit of 30 PIP or point. A PIP you canmake a profit of U.S. $ 10 depending on the capital invested. Byif you earn a profit of 30 PIP, this means you havea profit of U.S. $ 300 in 30 minutes. If converted toRinggit, you get a gain of approximately RM1, 200 in the30 minutes.What is PIP?
PIP is meaningful point. The term is often used PIP by traders during thebusiness. How pip or point is calculated or determined. Suppose youtrading on the currency GBP / USD at 1.8750 and the opening price riseuntil the final price of 1.8800. This means that the currency pair GBP / USD is just now beenincreased by 50 points or pips.WHAT IS A LEVERAGE?
Leverage is the meaning of "security margin". For example, if youhave an initial capital in the forex market or the stock of 100 USD. Thenif a subject is 1:100 leverage means that you are given the right bya forex trading platform to buy 100 x times greater than the fundsor capital you have. This means that the capital value 100 USD you canprovided funds to buy the currency worth 10.000 usd. Indirectlywith limited capital investment is you can pass on the volume of transactionsgreater trade.Each platform offers leveragenya own forex. In this case the leveragecould provide greater profits or greater losses. Sobut also by offering a small leverage the losses and gainsis at a smaller value. Here I show you an exampleleverage: -Leverage 1:100Capital 100USDPermissible investments 100USD x 100 = 10,000 usdWhat is Contract Size?"Contract Size" is a multiplier factor in the calculation of profit and loss.Value set by the country itself is in nialaian 10.000.

Trading the forex market deserves your serious consideration

Forex trading has enjoyed exponential growth and widespread popularity over the past

few years. It is only now that online foreign exchange trading is starting to get noticed.

Until recently, large international banks were the big dogs in the foreign exchange (FX or

forex for short) market, selectively allowing access via telephone trading to Fortune 1000

companies, large funds, high-net worth individuals, etc..

But now, there are online trading firms that provide individual traders like you and I with

direct access to the largest, most liquid financial market in the world – the forex.

A lot of traders seem oblivious to this market. This unfamiliarity is the root cause of

misconceptions about this exciting market.

Spot foreign exchange is the ideal market for active trading - more leverage than

equities/futures/options. The market is highly volatile, has a tendency to trend strongly,

and actively trades 24 hours per day. There are no limitations on when one can short a

currency. Currency traders can make money when a currency is becoming stronger or

weaker.

Tips And Info (Sore Throat)

2012-06-21T15:49:00.000+08:00

Sore Throat

Sore throat refers to the inflammation of the pharynx, or back of the throat. It occurs frequently when a person has a cold or an attack of influenza. This inflammation may also involve the tonsils and adenoids if these have not already been removed. An irritating condition of the throat may range from the harmless to the potentially serious.

Symptoms

In case of acute sore throat, the patient complains burning and dryness in the throat followed by chills, fever and some hoarseness or laryngitis. The lymph glands along the sides of the neck may become swollen and tender. The back of the throat may become very red and even covered with a greyish-white membrane. The patient may find difficulty in swallowing, especially during the acute stage. There may also be postnasal discharge if the irritation has spread to the nasal passages. The patient with sore throat, caused by ‘ Streptoccal’ germs suffers from high fever and sharp pain with swelling.

Causes

Sore throat is mainly caused by bacteria or a viral infection. Many different kind of ailments can give rise to this condition. The most common of these ailments are common cold and influenza.Other diseases which can cause sore throat are tonsillitis, mumps, sinusitis, measles, and diphtheria. Even leukemia on rare occasions may lead to sore throat. Other causes of this disease are excessive smoking and talking, frequent use of voice as in certain professions like singing, acting and teaching.

Treatment

The patient suffering from sore throat should fast on orange juice and water for three to five days, depending on the severity of the condition. He should take orange juice diluted with warm water every two or three hours from 8 a.m. to 8 p.m. during this period. The bowels should be cleansed daily with warm water enema. This should be done twice daily in more serious cases. A wet pack should be applied to the throat at two-hourly intervals during the day, and also one at night. The procedure is to wring out some linen material in cold water, wrap two or three times round the effected part, and cover with some flanner. The throat may be gargled several times with warm water mixed with a little salt. A hot Epsom-salt bath , taken daily during this period, will be highly beneficial.When the more severe symptoms subside,the patient may adopt an all-fruit diet for three or four further days, taking three meals a day of juicy fruits such as orange, apple, pineapple and papaya at five-hourly intervals. Thereafter he may gradually adopt a well-balanced diet, with emphasis on seeds, nuts and grains, raw vegetables and fresh fruits. The daily dry friction and deep breathing and other exercises should form part of the daily health regimen.

Home Remedies

Certain home remedies have been found to be beneficial in the treatment of sore throat. One such remedy is use of mango ( aam) bark which is very efficacious in sore throat and other throat disorders. Its fluid can be applied locally with beneficial results. It can also be used as a throat gargle. This gargle is treated by mixing 10 ml. of the fluid extract with 125 ml. of water.The herb belleric myrobian ( bahera) is another valuable remedy for sore throat. A mixture of the pulp of the fruit, salt, long pepper (pipli) and honey should be administered in the treatment of this condition. The fried fruit, roasted after covering it with a wheat flour, is also a popular remedy for sore throat.

Betel leaves (pan - ka -patta) have proved beneficial in the treatment ofthis disease. The leaves should be applied locally for obtaining relief. The fruit of the betel tree, mixed with honey, can also be taken beneficially to relieve irritating throat cough.

The bishop’s weed (ajowan) is valuable in treating sore throat. An infusion of the seeds mixed with common salt can be used beneficially as a gargle in acute condition caused by colds. The spice cinnamon (dalchini) is also regarded as an effective remedy for sore throat, resulting from cold. Coarsely powdered and boiled in a glass of water with a pinch of pepper powder and honey, it can be taken as a medicine in the treatment of this condition. The oil of cinnamon,mixed with honey, also gives immense relief. A gargle prepared from fenugreek (methi) seeds has been found very effective remedy for treating sore throat. To prepare this gargle, two tablespoons of fenugreek seeds should be put in a litre of cold water and allowed to simmer for half an hour over a low flame. It should be allowed to cool to a bearable temperature. It should then be strained and entire quantity used as a gargle.

The leaves of the holy basil ( tulsi) have also been found beneficial in the treatment of this condition. The water boiled with basil leaves should be taken as a drink and also used as a gargle in sore throat.

The patient should avoid rapid changes in temperature like hot sun-shine to air conditioned rooms. He should avoid cold and sore foods which may irritate his throat. To prevent the disease, a person should avoid touching tissues, handkerchief, towels or utensils used by the patients suffering from sore throat.

Tips And Info For Patients With Heart Disease

2012-06-20T17:53:00.001+08:00

Patients With Heart Disease

The term coronary heart disease covers a group of clinical syndromes arising particularly from failure of the coronary arteries to supply sufficient blood to the heart. They include angina peactoris, coronary thrombosis or heart attack and sudden death without infarction.There has been a marked increase in the incidence of heart disease in recent years. Heart attacks have become the number one killer in Western countries. They rank third in India, after tuberculosis and infections. The disease affects people of all ages and both sexes, although it is more common in men than in women, especially among those aged 40-60 years.

The heart, the most vital organ in the body, is a muscle about the size of a clenched fist. It starts working even before birth inside the womb. Weighing less than 350 grms, it pumps about 4,300 gallons of blood per day through the body and supplies oxygen and nourishment to all the organs. It beats 1,00,000 times a day, continuously pumping the blood through more than 60,000 miles of tiny blood vessels. The heart, in turn, needs blood for its nourishment which is supplied by coronary arteries Coronary arteries are so called because they are arranged rather like a crown or carona. In case of strain, etc., the heart needs more blood and the arteries, under normal conditions, adjust themselves to the increased flow.

In the event of narrowing or hardening of the arteries on account of their getting plugged with fatty substances, the flow of blood is restricted. The heart then does not get sufficient oxygen.This condition is known as ischaemia of the heart or angina pectoris. In this condition , exercise or excitement provokes severe chest pain and so it limits the patient’s physical activity. It serves as a warning to slow down and prompt preventive measures will prevent a heart attack.If the narrowed arteries get blocked due to a clot or thrombus inside them, causing death of that portion of the heart which depends upon the choked arteries, it is called a heart attack or coronary thrombosis. It may lead to death or heal, leaving a scar. Patients with healed lesions may be severely disabled or may be able to resume normal life with restrictions in their physicalactivities.

Symptoms

A common symptom of heart disease is shortness of breath which is caused by the blood being deprived of the proper amount of oxygen. Another common symptom is chest pain or pain down either arm. Other symptoms are palpitation, fainting, emotional instability, cold hands and feet, frequent perspiration and fatigue. All these symptoms may be caused by many other disorders. Appropriate tests and studies are, therefore, essential to establish the true nature of these symptoms.

Causes

The basic causes of heart diseases are wrong dietary habits, faulty style of living and various stresses. The famous Framingham Heart Study of the National Heart and Lung Institute identified seven major risk factors in coronary heart disease. These are : (i) elevated blood levels of cholesterol, triglycerides and other fatty substances ( ii) elevated blood pressure (iii) elevated blood uric acid levels (mainly caused by high protein diet), (iv) certain metabolic disorders, notably diabetes, (v) obesity, (vi) smoking, and (vii) lack of physical exercise. Each or a combination of these risk factors can contribute to heart disease. Most of them are of dietary origin. These risk factors can be controlled by changing one’s life style and readjusting the diet.Constant worry and tension stimulates the adrenal glands to produce more adrenaline and cartisons. This also contributes to constricted arteries, high blood pressure and increased work for the heart.

Treatment

The fundamental conditioning factor in all heart diseases is the diet. A corrective diet designed to alter body chemistry and improve the quality of general nutritional intake can, in many cases,reverse the degenerative changes which have occurred in the heart and blood vessels.

The diet should be lacto-vegetarian, low in sodium and calories. It should consist of high quality, natural organic foods, with emphasis on whole grains, seeds, fresh fruits and vegetables. Foods
which should be eliminated are all white flour products, sweets, chocolates, canned foods in
syrup, soft drinks, squashes, all hard fats of animal origin such as butter, cream and fatty meats.
Salt and sugar should be reduced substantially. The patient should also avoid tea, coffee,alcohol and tobacco.

The essential fatty acids which reduce serum cholesterol levels and minimise the risk of arteriosclerosis can be obtained from sunflower seed oil, corn oil or safflower oil. Several studies have indicated that garlic can reduce the cholesterol level in persons whose body normally cannot regulate the cholesterol fractions. Other important cholesterol lowering foods are alfalfa and yogurt. Lecithin helps prevent fatty deposits in arteries. Best food sources are unrefined,raw, crude vegetable oils, seeds and grains.

Fruits and vegetables in general are highly beneficial in the treatment of heart disease. Seasonal
fruits are quite effective heart tonics. Apples especially contain heart stimulating properties and
the patients suffering from the weakness of heart should make liberal use of apples and apple
jams. Fresh grapes, pineapples, oranges,custard apples, pomegranaes and coconut water also
tone up the heart. Grapes are effective in heart pain and palpitation of the heart and the disease
can be rapidly controlled if the patient adopts an exclusive grapes diet for few days. Grape juice,
especially will be valuable when one is actually suffering from a heart attack.

Indian gooseberry or amla is considered an effective home remedy for heart disease. It tones up the functions of all the organs of the body and builds up health by destroying the heterogeneous elements and renewing lost energy.

Another excellent home remedy for heart disease is onions. They are useful in normalising the percentage of blood cholesterol by oxidising excess cholesterol. One teaspoon of raw onion juice first thing in the morning will be highly beneficial in such cases.Honey has marvellous properties to prevent all sorts of heart disease. It tones up the heart and improves the circulation. It is also effective in cardiac pain and palpitation of the heart. Onetablespoonful daily after food is sufficient to prevent all sorts of heart troubles.

Patients with heart disease should increase their intake of foods rich in vitamin E, as this vitamin promotes the functioning of the heart by improving oxygeneration of the cells. It also improves the circulation and muscle strength. Many whole meal products and green vegetables,particularly outer leaves of cabbage are good sources of vitamin E. The vitamin B group is important for heart and circulatory disorders. The best sources of vitamin B are whole grains.

Vitamin C is also essential as it protects against spontaneous breaches in capillary walls which can lead to heart attacks. It also guards against high blood cholesterol. The stress of anger, fear, disappointment and similar emotions can raise blood fat and cholesterol levels immediately but this reaction to stress can do little harm if the diet is adequate in vitamin C and pantothenic acid. The richest sources of vitamin C are citrus fruits.

The following is the suggested diet for persons suffering from hypertension or some disorder of the heart :

On rising : Warm water with lemon juice and honey or fresh fruit juice of apple,grapes, orange, pineapple.

Breakfast : Fresh fruit such as apples, grapes, pears, peaches, pineapple, orange, melons, one or two slices whole meal toast, yogurt, skimmed milk or soya milk.

Mid-morning : Fresh fruitjuice or coconut water.

Lunch : Combination salad of vegetables such as lettuce, cabbage, endive, carrots, cucumber, beetroot, tomato, onion and garlic. One or two slices of whole meal bread or chappatis, curd, fresh grapes and other fruits in season.

Mid-afternoon : One or two wholemeal biscuits and fruit juice.

Dinner : Fresh fruit or vegetable juice or soup, two lightly cooked vegetables, one or two whole wheat tappets. The patient should also pay attention to other laws of nature for health building such as taking moderate exercise, getting proper rest and sleep, adopting the right mental attitude and getting fresh air and drinking pure water.

Water Treatment

The use of an ice bag on the spinal area between the second and tenth thoracic vertebrae for 30 minutes three times a week, a hot compress applied to the left side of the neck for 30 minutes every alternate day and massage of the abdomen and upper back muscles are water treatments which are beneficial in cases of heart disease.

Hot foot and hand baths are excellent for relieving the pain of angina pectoris. To this may be added hot packs on the chest over the heart for one minute and a cold pack applied alternately for five minutes.

Navigation And Detection

2012-06-13T14:59:00.000+08:00

During the 20th century,highly sophisticated ways of location objects were developed.Most of these developments were for military use,but civilian applications quickly followed.
Sonar and radar were developed to detect unseen enemy equipment from reflected sound or radio waves-sonar for submarines,radar for surface ships or aircraft in flight
Both radar and radio navigation make use of the fact that a loop aerial transmits radio waves in a narrow beam, rather than through 360 degrees
Sonar uses high - frequency sound waves because these travel very quickly and efficiently in water - radio waves do not travel through water at all

What is radar ?

Radar is a system for locating objects and navigation by transmitting high - frequency radio waves and detecting their reflection (echo).Pulse radar,the most common type,transmits short bursts of radio waves and calculates the distance to a target from the time it takes for the echo to return.A directional antenna means that the bearing of the target can also be calculated.

The development of radar occurred independently in Britain,France,Germany,the USA and Japan in the 1930s

Radar is now also used in ICBM early warning system and missile guidance, air traffic control,shipping,astronomy,meteorology,archaeology, satellite tracking and speed detection by traffiic police.

What is sonar?

Sonar is a system for locating objects underwater.

The Asdic system was developed by Allied scientists in 1917-18,it was rename sonar by the Us navy during the Second World War.
Active sonar detects echoes from sound or ultrasound (extremely high frequency sound) generated by the system itself
Passive sonar detects sounds made by the target, for instance a ship or submarine
Modern system are hull-mounted ,or operate from an air -launched sonobuoy or unit suspended from a helicopter,passive sonar arrays are also installed on a seabed
The echo sounder found in many private boats uses sonar echoes from the seabed to determine water depth

Radio navigation

Radio navigation was developed during the Second World War as a means of directing bomber aircraft to their targets at night

The German Knickebein (bent leg) system,developed by Hans Plendl from 1934 was typical.It use a radio beam transmitted from Kleve,western Germany,to guide an aircraft to the target (Morse signals in the radio beam warned to the pilot if he strayed off course).An interceptor beam from Breadstadt,northern Germany,signalled when the aircraft was over its targets .Britain's Gee system and the US Loran Were similar.

Modern radio navigation system include the VOR system of radio beacons in commercial air corridoors

EYE ON THE SKY The VOR system in combination with radar, enables air traffic to be controlled from a rellatively small number of centres on the ground.

Global positioning

The US Department of Defense's Navstar global positioning system (GPS) is the world's most widely used navigational system. Time signals regulated by atomic clock are transmitted by 24 satellites in precise orbit at least four satellites are always simutaneously within range of any point on the Earth's surface.Gps recivers in boats,car and even mobile phones compare signals from several satellites to plot a location accurate to a few metres.

PINPOINTED A GPS receiver calculates its distance from four or more satellites, as if it is on the surface of imaginary spheres centred on each of the satellites. The receiver's location is at the point where the spheres intercept.

** Note**

ASDIC: Anti submarine Detection Investigation Committee (an apocryphal Allied scientific committee of the First World War)
Gee: Grid navigation system
GPS: Global Positioning System
Loran: Long-range Radio Navigation System
Radar: Radio Detection and Ranging
Sonar: Sound Navigation and Ranging
VOR : VHF (Very High Frequency) Omnidirectional Radio

TIMESCALE

Electromagnetic spectrum info

2012-06-05T01:44:00.000+08:00

Core facts

Electromagnetic radiation is best understood as wave of energy,produced by oscillating electric and magnetic fields
Physicists divide this energy into a spectrum of named bands, according to frequency and wavelength. In this spectrum, our senses detect only heat (infrared) and visible light.
In a vacuum, all electromagnetic wave travel at a speed of roughly 300,000km per second -the speed of light.
Electromagnetic waves can also travel through matter, at speed reduced by up to a half

1.Radio waves

Up to 3000MHz use in radio and television broadcasting, telecommunications networks, cordless telephones, wireless computer networks, radio telescopes.

The usable spectrum of radio frequencies is devided into bands and regulated nationally and internationally to avoid interference between broadcasters.

2.Microwaves

3000MHz to 300GHz use in telecommunications networks, microwave ovens, mobile telephones, radar, microwave telescopes

Absorbed by water molecules in food to cook it in a microwave oven, but not absorbed by plastics or ceramics.

3.Infrared

300GHz to 400 THz Use in electric heaters, cookers, toasters, remote controls for VCRs, aerial surveying, night vision equipment, thermal-imaging cameras, infrared astronomy.

Prodused by warm or hot objects, and generally indentifiable as heat, detected by the eyes of some animals couses warming when absorbed

4.Visible light

400 to 700THz used in photography, cinematography, tv, power generation (by photocell). The range of radiation detected by human eyes, power photosynthesis in plants.

Splits into the colours of the rainbow, red ,orange, yellow, green, blue, indigo and violet.

5.Ultraviolet

700THz to 300PHz use in some night vision equipment,hospitals (for sterilisation of equipment), optical brighteners in washing powder.

Couses suntan and sunburn in humans, and some cancers can be detected by insect eyes, intense ultraviolet rays from the sun are absorbed by the ozone layer in the Earth's atmosphere.

6. X-rays

300 PHz to 30 EHz used in X-ray equipment (for observing dense internal body structures,like bones), checking joints and welds in metal, destroying cancer cells.

X-ray pass through many solids, including human soft tissue, can cause genetic mutation and cancers, can damage some electronic equipment.

7.Gamma rays

More than 30 EHz used in checking dense structures in engineering, destroying cancer cells.

DIY-Computer-Repair (Hard Drive repair)

2012-06-04T02:20:00.001+08:00

Most components in your system are expensive, the hard drive is no exception.

But if you think about the "bang for your buck" the newer hard drives are a super bargain. Consider this, one byte (8 bits) is equal to one character of typed text. Now you have a hard drive that has the capacity of xxx gig, that is xxx billions of single characters, how many books would it take to have say
300 gig of characters? A book case of encyclopedias? Two? Three? So a new300 gig hard drive costs say $130, you get a meg for about $0.0105, that is less than a half cent per 250,000 characters! Before we get to the actual replacement/upgrade we need to know what type of drive you have.
Is it a SATA (ATA Serial Drive) or IDE Drive? Each have different connectors for both the drive controller cable and the power connection. Replace or upgrade? Replacement of a hard drive is a fairly simple procedure, Safety First!

Open the case, look at the old drive (check the CD section for steps) note the cable positions. Disconnect the cables, remove the drive.
IDE only
Look at the back of the drive, check the drive select jumper, is this the only drive on the cable?
Yes: Then it should be set for cable select. No: Is the jumper set for Master or SlaveNote: SATA drive selection is set by embedded software. All Drives Reverse removal procedure.
Replace case cover, prepare to power up. (Check you computer documentation on how to get to the BIOS setup)
Power up, do you see the post?
Go to BIOS setup, your new drive should be listed. BIOS listings differ from manufacture to manufacture, if it is not displayed on the fist page, look for storage.
If this is a replacement drive that the OS (Operating System) was on then you will have to make sure that the drive is selected to be the Boot drive, also you will have to reinstall the OS. (check the programs listing for instructions on reinstalling your OS).
If this is a second drive and not the OS drive once you see it in the BIOS, check to see if it is listed as the boot drive, you do not want it to be the boot drive, change the setting.
Once you are confident that the drive settings for the bios are correct exit and let the OSload. Once the OS is up and running you have to do two more things before your new drive is ready: Partition the driveFormat the drive

Basic Electricity

2012-06-03T17:21:00.000+08:00

Electricity is motion of electrons in certain materials. When electrons (containing “ – “ charge)starta moving towards protons (containing “ + “ charge) this motion causes flow of numerous electrons. This flow is called electricity.

Basically the force that forces eletrons to flow is measured in “Volts” whereas the quantity of electrons flown in certain time is measured in “Ampere’s”

Formation Of Electricity

There are two types of electricity according to its form

1. 1. AC (Alternating Current)

2. 2. DC (Direct Current)

1. AC (Alternating Current)

Alternating current is the type of current in which both current flow lines bear both type of charge “+” and “ – “

In AC both lines contain “+” charge for a certain time and “ – “ afterwards so it forms a wave in which the supper level from “0 level” is “+” and lower level from “0 level” is “ – “. See figure 1.0

Sources of AC:

Commonly AC is supplied in Mains supply used in commen home electrical appliances. It is produced by “Dynmo’s” , “Turbines” and “Generators” and also in “UPS” normally proveded AC in homes is measured 220 Volts and its Frequence(cycling speed of “+” and “ – “ charge) would be 60 Hz(hertz frequency measurment units). And in some countries it would be 110 Volts and 50 Hz.

2. DC (Direct Current)

Direct Current is derrived from its shape. The charactristic of DC are

1. 1. DC is not in wave form rather it is straight

2. 2. DC contains “+” charge on one line and “ – “ charge on another line( See Figure 2.0

Sources:

Normally sources of Direct Current are batteries, Cells, Solar Cells and DC Adapters and Chargers.

AC To DC Conversion

“AC” can be changed into DC as well as DC into AC. While converting AC into DC we need a few components calles detectors commonly known as Rectifire Diods. The complete function of Diods is discussed in “ Parts Detail and Function Lesson”, but here I want show the simple process in which “AC” is converted into “DC”. First of all we should know the main differences between AC and DC.

1. 1. “AC” contains “+” and “ – “ cahrge in wave form whereas “DC” contains “+” and “ – “ charge in straight shape.

2. 2. “AC” contains both “+” and “ – “ charge on both lines whereas “DC” contains “+” charge on one line and “ – “ charge on another line.

So it is easy to convert “AC into “DC” by straightening charge shape and by making it seperate.

Note: this circuit with some modifications is used in mobile phone chargers.

Network Card repair

The network card allows you to connect to other computers either locally or over the World Wide Web (internet).
Before we get to involved with trying to fix a network problem this site can not give you all the steps you will need to fix a network problem, it is just too complex. I can how ever help you trouble shoot it for the most common problems, if these steps fail you will have to call a local tech to assist you. By using this guide you may save your self some money by fixing it your self.
These cards are a go no-go type of component. They either work or they don't. However most problems with network card are caused by configuration failure.
By configuration failure I mean that the card is getting the wrong information to allow it to do it's job. If you have reseated the card, checked the cable is connected and still having problems connecting then the next step is to trouble shoot the configuration.
Steps:
A) Go to start, then accessories, then command prompt. Type in - ipconfig
You should get a listing like this: Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . : homecomp
IP Address... ………………. : 192.168.1.4
Subnet Mask .. . . . . . .... . . . . : 255.255.255.
Default Gateway . . . ... . . . . . : 192.168.1.1
If you do not see this then you are having a configuration problem, you need to check the properties for the network card. If you see this go to how to check for connectivity.
B) Check the properties of the card in computer management/device manager. Does it have a red circle with a slash over the icon? Does the properties say "Device is functioning normally" or does it say "The drivers for this device are not installed. (Code
28)" or something similar? (go to reinstalling card/drivers)
C) If the card is green and the properties display "This device is working properly." you may have a configuration problem.
D) Go to My Network Places, right click, select properties from menu. Network properties opens, do you see the "Local area Connections" or just "New Connection"? Right click on the "Local area Connections", select properties from menu.
E) DHCP Settings: When you look at the properties page you should see at a minimum four items that are checked. The main item of concern in the box labeled "This connection uses the following items:" The one you want to check is labeled "Internet Protocol". High light it and go to the properties button. When it opens the area we are looking for is "Obtain an IP address automatically" the radio button should be checked, the boxes below should be grayed out. Close the TCP/IP Protocol page.
F) Static IP Settings: The main item of concern in the box labeled "This connection uses the following items:" The one you want to check is labeled "Internet Protocol". Highlight it and go to the properties button. When it opens the area we are looking for is the IP, Subnet Mask, and Gateway. Normally these would not be set unless you have a Local Area Network setup with a DNS server. If this is the case you need to know what the ip, subnet mask, gateway, DNS, and Wins addresses are for you LAN. If you hired someone to setup your LAN they should have gave you a configuration document, if not you may have to call them to get the information. If any of these parameters have changed, you will not be able to connect.
Scenario: No connectivity!

Lets say you can not connect, you can do not have an ip listed when you run ipconfig. You can do a little trouble shooting before you call the "Geek Squad".
Setting the IP
If your system is set for DHCP and you are getting your IP from your
Cable Modem or DSL Router you can fake it out by entering your own ip.
Most generic Cable Modems and DSL Routers use this subnet to give you an IP:
192.168.1.X where X is any digit above 2. If you have more than two computers connect to your Cable Modem or DSL Router use this ip to fake out the DHCP: 192.168.1.130, you will also have to set the subnet mask: 255.255.255. and set the gate way:192.168.1.1
Don't worry about the lower block for DNS.
Now go to the command prompt you opened and type: ping 192.168.1.1
You will either get a reply from the Cable Modem or DSL Router or you will get a time out on the reply.
If you get a reply from the ping then shut your system down and restart, once it is running again go back to the network properties and remove the ip address you put in, just check the DHCP radio button, apply changes, this should take a short period to complete.
Go to the command prompt, type in ipconfig, does it look like the sample?
If it comes back with an ip, in the command prompt type: ping 192.168.1.1
Do you get a reply? Yes?
From the command prompt type: ping www.google.com
Reply? Yes? Fixed.
