I have a WRT54G v5 router that, after two years of successful operation and no change in settings, dropped connectivity on both wireless and wired connections - Windows simply says "limited or no connectivity". The client computer doesn't get an IP address, even though it's set up to get one through DHCP. I reset the router, unhooked it from the cable modem, and re-booted the pc in all possible orders, but nothing works. I've even tried a static IP address configuration (including gateway/dns settings) using the addresses that I remembered were set by DHCP when the setup was still working - but while that did seem to restore connectivity (because the Windows error message went away), I still was not able to get to the router's admin login page, let alone browse the web. When I bypass the router and plug the ethernet cable from the cable modem straight into my laptop, I get onto the internet just fine - so it really is a router issue. Because I cannot get any connection to the router, I can't login to the admin module to change settings or do a firmware upgrade - so it seems I've hit a dead end. To me, it seems the DHCP routine got screwed. Any suggestions on how to solve this? Or does this mean my router is fried and should be replaced?
