My XBox can't seem to get an IP address. Things I have tried:
-Gone through the network support tree (restart router, manual IP, etc.) with my Belkin router
-Gone through the network support tree with my Netgear router (and a different root IP address)
-Gone through the network support tree with the XBox connected to my laptop with a network bridge
-Tried multiple LAN cables
The Xbox can tell that a cable is plugged in. The "wired network" option is checked and hardware lights work on routers. BUT, the router can't see the XBox. It doesn't detect anything with the XBox's MAC address whether I use DHCP or manually set an IP address.
I noticed it last week so it doesn't have to do with the latest update. If it were a PC, I'd try re-installing and/or rolling back the network drivers, but that's not an option. I do not have a wireless modem or any other USB-based network hardware to plug the XBox into. Is there some sort of "hard reset" or way to delete any updates that might have changed LAN settings?
In a related question, if I'm stuck with a XBox that can't connect to Live, is there a way to pause my Live membership?
