There are two main reasons why gaming systems won't connect to the wired network:
1) One of the main reasons that gaming systems wont connect to the network is because the SafeConnect manager that regulates what can and cannot use the network sees them as an unknown device. So a way to tell the manager that your device is in fact an XBox 360/Xbox One which is covered by our SafeConnect system, is to run the Internet Connection Test.
If you are not able to connect to the internet with your XBox system then go to XBox Live and try to sign in a few times, this should create enough traffic to let the manager know that this is a gaming system.
2) If you still can't connect to the network after following the instructions in #1, call the ITS Help Desk at 619-260-7900 or email email@example.com The port in your dorm room may have been deactivated due to inactivity and ITS will need to reactivate it.
