To get the ball rolling, initial link to Gultig's message in the breaking news section: http://www.linux-hacker.net/cgi-bin/UltraBoard/UltraBoard.pl?Action=ShowPost&Board=bnews&Post=845

Link to the Seattle Wireless page on the WRT54G: http://www.seattlewireless.net/index.cgi/LinksysWrt54g

Link to a router-centric x86 mini-linux distribution for the GCT/Allwell (Websurfer Pro) boxes, or for old 486s begging to be converted into firewalls: http://www.routerlinux.com

Perhaps some of the apps in routerlinux can be recompiled into the mipsel-based distribution for the Linksys (or vice versa).

The Asus WL500B, WL500G are also based on the Broadcom BR47xx reference design, although with several implementation differences. It also has USB, which would allow faster test/debug/build cycles by using USB mass storage (e.g. USB memory key or similar) to hold a rootfs or a part of the rootfs. Here's a link to a forum that hacked it initially (also linked from the Seattle Wireless page).

http://www.chupa.nl/forum/

My idea is:

1) Build a kernel with initrd, USB, USB-storage support;

2) Use a minimal userland in the init ramdisk, with a statically-linked busybox and an init script that just checks if a USB mass-storage device is present and mounts it somewhere;

3) On the USB mass-storage, build a comprehensive userland. In particular, a minimal userland may be busybox/uclibc based, but a more comprehensive one may be glibc based. It could even be an RPM-based mipsel distro like the ones on the Malta or similar development board from MIPS.

4) The init script does all the module initialization stuff, and finally chroot to the USB storage mount point. Voila! you have a full linux userland.

This would allow rapid changes and rebuilds, without having to frequently flash the bootROM on the device, which is risky.

Dropped by Frys Electronics today and they have a special on the WRT54G! $79 after a $10 rebate. The ones at my store were version 1.1, which are the ones that have the unused PCMCIA header!! I believe that this deal is only good till the 27 so hurry.

If you compare this on froogle, it's a smoking deal. http://froogle.google.com/froogle?q=wrt54g&scoring=p

Get More From Your Router
Tinkering with modified WRT54G firmware

Written by Karl Bode

A fairly common VoIP complaint (depending on configuration) has been choppy communications when users are throttling their broadband connection. To that end, users are tinkering with modified router firmware upgrades to incorporate bandwidth management and a host of other free improvements. This thread in our VoIP forum outlines how one user obtained the quality of service he was looking for with a Linksys WRT54G and Linux based modified firmware from Sveasoft.

The modified firmware has incorporated Wondershaper bandwidth management, allowing users to avoid choppy conversations while gobbling up bandwidth with other applications. Of course that doesn't just apply to VoIP, the firmware allows you to prioritize any important traffic across your network.

The improvements don't end there either, as the firmware also incorporates a number of networking improvements and upgrades, boosts power levels, and adds quite a number of treats to the router's web-interface.

A list of all the features added to the Sveasoft Linksys build is here. Discussion over at the Sveasoft forums tackles what kind of additional functionality users would like to see (such as which VPN software customers most prefer). You can download the firmware here at the Svesoft website, then find detailed instructions on getting up and running here in our forums.

Sveasoft isn't alone in offering modified firmware; there's also the Wi-Fi Box firmware that users in our Linksys forum have been discussing for the past month. It's an impressive way to get quite a bit of added functionality out of a piece of sub-$100 hardware ($80 at Amazon).

If you do put it outside or up on the roof, make sure you
put on some type of lightning protection!! Ground it all
well, and add a grounded metal spike up there!

Robert X. Cringely seems to have 'got it'. Article (already slashdotted) on the disruptive potential of inexpensive mesh wireless routers, with special reference to the Linksys WRT54G:
