Built-In Adapter
Before you begin hunting for an Xbox 360 wireless adapter, double-check which version of the Xbox you own. The Xbox 360 S has a built-in wireless adapter and can pick up wireless networks without the need for additional hardware.
Microsoft Xbox 360 Wireless Adapter
The Microsoft Xbox 360 Wireless Adapter was built by Microsoft to help connect the 360 console to a wireless network. It connects via USB to a port on the back of the console. Configure the adapter to find your network, allowing you to share data, play online games and stream marketplace content.
Microsoft Xbox 360 Wireless N Adapter
The Microsoft Xbox 360 Wireless N is similar to the original wireless adapter, but was released later into the 360's development cycle. The adapter connects to the 360 through the same USB interface but includes better security features, a larger range for connecting to routers that may be out of sight and a faster overall connection speed.
