Instructions
Plug one end of the Ethernet cable into the available port on the back of your DSL-360T. Connect the other end of the cable to the port on the back of your Xbox or Xbox 360.
Start the console without a disc inside. This will allow you to boot into the system's dashboard.
Navigate to the setup tab and test your network connection on your Xbox. If using an Xbox 360, your system will automatically try to connect to Xbox Live when loading the dashboard.
