OpenWRT

There are various articles describing how to install and run Debian GNU/Linux on USB flash memory on an Asus WL-500W. This guide differs in that it will provide a complete end-to-end set of instructions. All you need is an Asus WL-500W, USB flash memory (say, 2 GB in size), a computer to build the firmware and Debian root filesystem, and an Internet connection to get the source code for OpenWRT and packages for Debian.
