I'm on comcast and today something happened with their network, apparently, tho on the second call to tech support they said they had no record of what the first contact person said. Since then I am not able to get my WRT54GS back online in any meaningful manner. I had a more complex setup where a dlink DFL-200 (192.168.1.1) was the first router off of the cable modem, handling some public facing test servers, and the WRT54GS (192.168.2.1) was off the dlink, handling LAN stuff. But after everything stopped working I've removed the dlink and have the WRT54GS connected on it's internet port to the cable modem (because the dlink router software is so awful, and the linksys software is pretty good, and because I have had such good luck getting useful feedback from linksysinfo people). But the WRT54GS does not seem to acquire an IP address from comcast. The dlink had the same issue. I have unplugged the WRT for two hours; hit the reset button for 15 seconds; and the IP address ion the Status page (linksys firmware ver 4.71.1) is always 0.0.0.0. I expect it to get a real ip address from comcast. I've tried the DHCP Release and DHCP Renew buttons numerous times; 0.0.0.0 is all I get. I was on the phone with comcast tech for a while re this issue; the cable modem and the connection seem ok. This WRT54GS is one of the early ones, ver 1 or something, if I recall. I'm able to write this because I connected the cable modem to my workstation directly; and thus I get a valid comcast ip address and can connect to internet. Am I missing something basic? What should I try next?
