Linksys produced hundreds of these routers for Rogers and T-Mobile for a voip project that was canceled. Both are essentially the same as the WRT54GS v3 (they have 8 MB flash and 32 MB RAM) and thus can be loaded with the WRT54GS v3 Broadband Hamnet firmware. Many of these Rogers routers (in Canada) and T-Mobile routers (in the USA) can be found still sealed in the original packaging.

A zipped file with instructions and all required files to replace the original firmware with bbhn can be downloaded from: http://ve3rrd.ddns.net/files/Broadband-Hamnet on WRT54G-RG and TM.zip
