I have my Xbox connected directly to the router through ethernet cable. It was working about 5 hours ago, watching movies on Netflix. Fell asleep and turned my Xbox back on, and now it isn't detecting the wire. In the test connection screen it shows up with the check mark in the corner of the wired connection, indicating that it is connected, but turns off and on alternatively every few seconds. I've tried different cables and tried restarting the router. I have read other forums discussing the same problem and their hasn't been any power surges and I have never opened up my Xbox. Can anyone help me figure out how to fix it or what I could do?
