Running Win XP SP2 using a SB4200 cable modem and Linksys WRT54G router. Installed the wireless router last night and the connection worked but kept randomly dropping. This morning I updated the firmware to HyperWRT hoping to use that firmware to boost my reception and all things went to h***....

Since the moment I updated the firmware I cannot obtain a viable IP address from my cable provider (Comcast) as I'm getting a 169.xxx IP address. I've tried plugging both my desktop and laptop directly into the cable modem with the same problem. I've reset the cable modem, tried a different router, nothing works. Any clue how my firmware on the router could have caused my cable modem to not sync up with Comcast to produce my IP. I called comcast and as always they are useless.

Thanks
