Equipment: Linksys WRT54G2 router, Arris TM602G cable modem + Ambit U10CO18
OS: Windows 7 Home Premium 64-bit
ISP: Cox Communications
Ever since I moved I've had nothing but trouble keeping a connection with my modem/router. We just moved down the street and have the same ISP as before, but something is going wonky at this house.
The issue seems to be that DHCP just simply isn't working. Within 1-2 hours of powercycling all my network equipment I lose the ability to access my router's configuration page. In addition, every time I start my computer up it takes at least a minute before I'm able to access the Internet; my systray shows that my computer is trying to identify its network during that time. ipconfig /release and /renew doesn't work. It gets hung up on renewing and then gives me the error 'Unable to contact DHCP server.' I've cloned my PC's MAC address which had no results. Plugging the ethernet cable into a different port doesn't work (and besides, the problem affects wireless as well). I've tried two separate modems and gotten the same results. My router's firmware is up-to-date, and it's configuration settings are all correct--or at least the same as they were in the old place when it worked perfectly.
Bypassing the router and plugging straight into the modem works just fine. So obviously the problem has to do with the router, but I don't think it's my hardware that's failing, as everything worked perfectly in our last house--unless by some amazing coincidence my router went bad on the exact day that we changed homes. Could there be something weird with the wiring in our new home which is causing this issue? Also, how is it possible that I'm able to access the Internet while not being able to access my router/DHCP server?
