Installing Linux on a Buffalo WHR-G125

I recently purchased a Buffalo WHR-G125 wireless router from a local Circut City for a mere $39.99. I was on a mission to find a router that supported dd-wrt and/or OpenWRT. This router supports both (although http://toh.openwrt.org/ still reports OpenWRT as a WIP). The WHR-G125 sports a 240MHZ processor, 4MB of flash, and 16MB RAM. It is based off of the Broadcom chipset.

Since OpenWRT was listed as a WIP, I decided I would install dd-wrt. I followed the instructions found here: http://www.dd-wrt.com/wiki/index.php/Installation. After making sure tftp was installed on my machine, I carefully reviewed the instructions and downloaded dd-wrt v24 beta. Unfortunately, the Buffalo firmware is encrypted, so it is a little tricky to flash with dd-wrt (it is a matter of good timing). I found that the one line command:

tftp 192.168.11.1 -m binary -c put dd-wrt.v23_generic.bin

worked just fine. After making sure that I could ping the router at it's new IP address (192.168.1.1), I opened Firefox and entered the dd-wrt control panel.

At this time, for some reason I am unable to manuever the control panel due to the rejection of the defualt user and password by the control panel. I am unsure what caused this problem, I plan to reflash the router with a non-beta version of dd-wrt ASAP.

All in all, this is a great little router for the price, and I am looking forward to using it as a local AP for my dorm room. The wireless signal range is not that great, however it will suit my purposes perfectly.

UPDATE: My login issue was simple to fix. I did not need to reflash the router. The Buffalo firmware has a defualt user/password combination of root/Blank. dd-wrt sets this to root/admin. The dd-wrt installation wiki does mention this for a different Buffalo router, it also applies to the WHR-G125. Thanks to Tomm Smith for pointing this out to me.
