Open Source Router Firmware – turbocharge your cheap router
PaulSpoerry | March 20, 2008
Wired How-To Wiki shows you how to basically turn a $50 router into a $300 professional grade router using open source firmware.
High-end commercial routers offer features that just don’t come with your basic home package cheaper routers. We’re talking features like quality of service (QoS) management, adjustable transmission power, and support for IPv6. Not everybody needs these features, but if you are somebody who does then you can get those features on the cheap using open source firmware.
What You’ll Need
- A compatible wireless router
- An Ethernet cable
Customize Your Router
This process involves replacing the manufacturer’s firmware that comes installed on the machine. There are quite a few open-source projects developing alternative firmwares for home routers. Each offers a variety of features and advantages.
DD-WRT is one of the most mature such projects, based on a Linux kernel and offering a wealth of options. Tomato is another firmware choice. Though not quite as feature-rich as DD-WRT, it is significantly easier to work with.
Find a Compatible Router
Linksys’s WRT54GL, shown above, is a good choice. It runs about $40- $60. Older models in the WRT54G series, without the L suffix, work: the WRT54G and WRT54GS versions 1 through 4 work without modification, and the version 5-6 work with ‘micro’ firmwares like DD-WRT micro thanks to the hack that can be found here. Look at the serial number on the underside of the router to check its version. Other routers that use Broadcom chipsets, made by Buffalo, Asus, and others, work as well.
There are numerous firmwares available for this platform. OpenWrt [1] provides a base for most of these firmwares, which extend it through a web based management console. Popular projects include X-Wrt [2], DD-WRT [3], and Tomato [4].
DD-WRT is compatible with a somewhat wider range of routers than Tomato is. Consult Wikipedia or the DD-WRT site for a complete reference.
Get the Firmware
Download the latest firmware, whether it be OpenWrt, X-Wrt, DD-WRT, or Tomato.
For some reason, Tomato is packaged as a 7z archive, one of the less-common file formats. You’ll need to unzip it with a tool such as 7-Zip for Windows, 7zx for Macs, or p7zip for Linux.
Unpack the downloaded firmware into a directory on your computer. It includes several different .bin files for different routers.
Install the Firmware
Follow these steps:
1. Plug your router into a power socket. Do not connect it to the Internet.
2. Use an Ethernet cable to connect your computer to one of the router’s LAN ports. Do not use a wireless connection for this, since if the connection dies while you’re installing the firmware, your router may become unusable.
3. Go to the administration page of your router. In a default setup, this is probably accessible at http://192.168.1.1/ . You’ll need to log in. The default Linksys username and password is admin/admin.
Changing the Linksys router’s firmware
4. Go to the Administration tab, and choose Firmware Upgrade. (This is standard for a Linksys router; other routers may offer this option in a different place.) It offers a slot to choose a firmware file from your computer, which will be installed on the router. Browse to the Tomato directory you created and choose the appropriate .bin file for your router. For a Linksys WRT54GL, for instance, choose WRT54G_WRT54GL.bin. Click the Upgrade button and do not interrupt the connection until the process completes! When it’s done, your router will reboot itself. When it returns, it’ll be running Tomato.
Use the Firmware
Monitoring network traffic in real time is just one of the tricks Tomato’s open firmware can do
First, change the administrator password to something that’s not the default, so random internet people can’t log in and change your settings. Tomato’s options are all laid out in a sidebar: click Administration and then Admin Access to get to the password page.
Now connect the router to the Internet and play around.
- One popular thing to do is to boost the transmission power: you can crank it all the way up to 251 mW. But this is unneighborly. It interferes with other signals in the area. It’s also somewhat useless — laptops will be able to find the router’s signal from farther away, but they won’t be powerful enough to transmit back to it at that distance, so the connection won’t work. Be smart and bump it up to 70mW.
- Set up some QoS rules. That way, you can make sure that your high-priority tasks (web browsing, gaming or VoIP) get all the throughput they need, while lower-priority tasks like BitTorrent downloads don’t eat up the bulk of your bandwidth.
- If you have kids (or leeching housemates of another sort), you can gain finer control over their access to the internet. Block P2P file transfers or ActiveX traffic at the router. You can also turn off wireless access during certain times of the day.
- Use your new firmware to run Dynamic DNS, which is essential if you want to set up a mail server, run a BBS or share your music collection through a web interface.
