United States of America, Ohio
This Gateway is NOT UPnP compatible.
According to the diagnostics via Call of Duty Black Ops II my NAT type is open.
I turn the console on and it does not connect to Xbox Live. It does sign in my profile but does not connect to live. When I attempt to connect it gives me ERROR CODE 80151901.
ISP is AT&T U Verse
I have talked to AT&T support. They are coming out tomorrow to install new equipment and provision me with a static IP address. I'm not sure that this will resolve the issue. Any help you can offer will be greatly appreciated.
