My Xbox won't connect to Xbox Live, and won't even allow me to test my connection! I hit test connection, and I choose wired, and it says, "To use a wired Internet connection, make sure an Ethernet cable is connected to both your console and your router or modem." AND IT IS! I even plugged the Ethernet cable directly into my laptop and the internet worked just fine. I've tried restarting modem and router, I've tried restarting Xbox, but still have the SAME problem. SOMEONE PLEASE HELP ME!
