Connect your Xbox 360 to a wireless network to join the world of online gaming. When you connect your Xbox 360 to a wireless network you can access Xbox Live where you can play against other online gamers around the world.
Online gamers can also participate in tournaments and operate in teams with each other for a whole new game experience. All you need to get started is a wireless access point and an Xbox 360 wireless networking adapter.
You won't be able to connect to Xbox Live unless you have a high-speed Internet connection, such as a cable or other broadband system.
Turn off all your network equipment (modem and router) as well as the Xbox 360.
Leave all equipment off for a couple of minutes.
Attach your Xbox 360 networking adapter to the back of the console and flip up the antenna.
Line up the adapter with the two slots on the back left corner of the Xbox 360. Insert the tabs on the adapter into the slots and plug the adapter's USB cord into the port next to it.
Turn on your modem and router. Make sure that your wireless router is connected to the Internet and broadcasting a signal.
Use a PC to ensure that all router settings are complete before turning on the Xbox 360.
Turn on the Xbox 360. Select My Xbox→System Settings on the dashboard.
If the Xbox 360 is connected to a modem using an Ethernet cable, the wireless function will be turned off.
Choose Network Settings and select Edit Settings. Select Wireless Mode.
The Xbox 360 will display a list of available networks.
Locate your home network's SSID on the list.
If you don't see your network and you’re sure that it was broadcasting a signal, try choosing Specify Unlisted Network.
Use the onscreen keyboard to enter your network's security key and select the type of security you use — WEP or WPA.
The Xbox will store all these settings and return to the Network Settings menu.
If you're not sure what the security key is, ask the person who set up the network initially.
Choose Test Xbox Live Connection.
The Xbox will attempt to log on to Xbox Live. You'll be able to watch as each aspect of your network settings is confirmed. Once it is all confirmed, the settings will be permanently stored so that you can quickly connect next time.
