Things You'll Need
Instructions
Get the wireless network identification name, called an SSID, and the password. This is often marked on a label on the side, or underneath of the wireless router. If it isn't, the SSID is the same as the one used to connect your laptop in your home. The person who set the network up will be able to tell you the password.
Select the Xbox "Dashboard" settings on the Xbox 360 and choose "Wireless Networking." Then follow the prompts to enter the SSID and the password.
Turn off the Xbox and the router if the Xbox won't connect to the Internet. Wait a minute and then turn them back on again. Turn the router on first and allow it to stabilize. Then turn on the Xbox. If you still can't connect, move the Xbox closer to the router.
