How to Connect to the Internet With the AT&T Air Card to Play XBox Live

Connect the AT&T air card to a computer using an available USB port. When connecting an AT&T air card to a laptop or desktop computer for the first time, it will take the computer network a few moments to recognize the new hardware. Once the hardware is recognized and installed, the computer network will walk the user through the process of setting up a new wireless Internet connection. After the initial setup, the computer network will automatically recognize the AT&T air card when it is used.

Access the computers "Network Connections" on the computer's Control Panel. Find the AT&T air card connection, which should appear as a wireless network connection. Right-click the AT&T air card connection and select the "Properties" menu. Enable "Sharing," which allows other computers to access the wireless connection.

Connect the computer using the AT&T air card to the Xbox 360 using an Ethernet cable. The Xbox 360 must be turned off before connecting it to the computer. Plug the Ethernet cable into the Xbox 360's Ethernet port on its back panel, before plugging the other end of the cable into the computer's Ethernet port.

Turn the Xbox 360 on and wait until the dashboard appears. Once the Xbox 360 dashboard is visible, scroll through the options and select the "my Xbox" menu. After reaching the "my Xbox" options, scroll to the right to "System Settings." Select the "Wired Connection." Test the new connection by returning to the Xbox 360 dashboard and signing into Xbox live.
