This is how to get UPNP sharing working from your router using MiniDLNA. I also got sharing working via UShare, but will write this with MiniDLNA because ushare is less compatible and no longer in development. This is a pretty straight forward and simple process if you're familiar with working in the DDWRT environment. The guide is derived from my install using a Buffalo WZR-HP-G300NH

I'm a big fan of Asterisk on router -- imho, it's the perfect platform for anyone want to try Asterisk at home -- 24x7, fanless and even the cheapest router can handle at least 2-3 concurrent conversation. Before this WZR-HP-G300NH, I had Asterisk running on a WRT54G-TM for over a year with lots of fun. Installing Asterisk on the router is easier now as current OpenWrt trunk build(the one

Busybox httpd is good for simple static pages, now here is a tutorial for installing lighttpd and php with fastcgi support in the router. Here I choose lighttpd over Apache for its light cpu usage and small memory footprint. Since all our software are based in /opt folder, some modification must be done to get everything working: Install php5 and lighttpd To install php5 with fastcgi support

By default DD-WRT runs its own http server (/usr/sbin/httpd), providing web management interface to configure the router. The server is highly integrated and hard to reuse for our own contents. If you just want to host some web pages without CGI support, the httpd server in busybox is a good alternative. (Optional) Move DD-WRT's web admin to another port The best way to do so is changing a

***This has been fixed in newer builds of DD-WRT - Check yours before continuing*** This never looks to be a problem since DD-WRT provides such extensive options. Unfortunately, unlike Tomato and OpenWrt, which do a good job, DD-WRT's approach is way off and completely wrong. A Linux box can keep its time in either local time or UTC -- both are fine as long as the corresponding time zone

The DD-WRT support for these new 11N Gigabit routers are still in early stage with new builds rolling out every one to two weeks. The old good "if its not broken then don't fix it" rule might not apply here and I suggest to stay with latest release if you have the time(and guts). Upgrading a DD-WRT firmware with loaded software is pretty easy, considering the extra work we've done. Take the

Stuck beacon is a notorious problem on madwifi (the wireless driver DD-WRT used for Atheros routers).  If you never experienced any wireless interruptions with DD-WRT then just ignore this article. However, if you're annoyed by this stuck beacon problem with constantly dropping wireless connection, then I hope this can be of help. Below is a quick hack, not a completely fix but would

Cron is a time-based job scheduler in Linux systems which enables users to schedule jobs (commands or shell scripts) to run periodically at certain times or dates. In this example, we'll use cron to control the wireless signal, and set it to turn on only at given time. DD-WRT is shipped with cron support, but again we'll use our own cron daemon as it's easier for future updates and will save

If you've followed the previous guide to set-up the opkg system, then installing transmission on the system is a no-brainer. The configuration and system set-up can be a bit more difficult, but not bad at all. We will install the Transmission daemon, web access, and remote access. Optionally, you can grant WAN access and user/password security. Let's get started. Install transmission To do so,

Hotplug is a set of scripts running upon certain predefined conditions. On today's Linux system, hotplug can do many things from auto mounting USB drives to pairing bluetooth devices to network configuration. It's seldom mentioned, but DD-WRT does offer (very preliminary) hotplug support. With almost no info on the web, the job is done by digging though DD-WRT's source code and various Linux

Since there's USB port on the router, any normal USB printer can become a network printer. As the router is usually on 24x7, there is no need to invest in a (usually overpriced) dedicated printer server. The printer server program that we use here is p910nd. It's a very small (only 8KB) daemon which simply redirects all printing command from a PC to the printer. Setting up p910nd on the

I generally prefer Samba over FTP, as it gives a better experience by allowing user to access the files as if they're still on local disk. And, unlike FTP, media files can be played directly from Samba. But, one might still need a FTP server as it offers better performance over Samba. If the router has at least 8MB flash ROM and happens to run DD-WRT MEGA build, it is very likely there is a

It's not easy to configure Samba in standard DD-WRT because, by default, the /etc folder is read-only. So before starting, please set a writable /etc. Also, DD-WRT does have a Samba3 built in the firmware and it works just fine, you're just not able to configure it fully. In this guide, you'll be guided through the whole process to set up a password protected samba share with custom

One great thing about this router is its loaded hardware specifications: 400MHz processor, 32MB flash ROM, 64MB RAM and most important of all, a USB port. All these make the router a very versatile little Linux box with tons of capabilities.  However, a confusing thing that inexperienced users may not know, the CPU in the router is MIPS (MIPS in big-endian), while the popular

Though the whole flashing process can be done via web interface without getting your hands dirty, there are cases that the web upgraded is not practical or possible. One common scenario is a semi-bricked router (no web access and no ping response due to bad flash or invalid operation, or you just want to try other firmware like OpenWrt). Luckily that the WZR-HP-G300NH has a robust

Flashing DD-WRT on this router is extremely easy - thanks to the hard work of DD-WRT developers and the official partnership with Buffalo. The official Buffalo DD-WRT version has a few bugs, and lacks support for a media sharing program that I use (minidlna - I will add a tutorial for it later), so I recommend downloading the latest stable snapshot from DD-WRT. Flashing from stock to OpenWRT,
