My wireless laptop computer logs on to the internet without fail , but when I try to log into XBOX live with my XBOX it will sign in for about 10 or 20 seconds and then all lights on router go off and reboots. Have never had any trouble before now. I have internet through a cable company, I'm wondering if its the router or the internet or my XBOX. and what do I do to remedyCable T.V. has no trouble.

Tried my PS3 also and it will not connect either...........Has anyone else experienced this problem. I gotta get it fixed, having multiplayer withdrawls
