Since September of last year we haven't been able to play online. I run the test and it tells me can't obtain ip address from modem or router. I have ATT and they said they could fix for $100...I'm not paying that. I did every single test out there and nothing. Has anyone had this problem and got it fixed without having to pay? I have a 2wire modem DSL and that is connected to my computer and the xbox is in a diffrent room and I have an adapter that att gave me so we can play online, so we wouldn't have our modem plugged in directly to the xbox.
