Even though this is just a wireless B adapter, it will handle all the bandwidth that Xbox LIVE can throw at it. This works for both the original Xbox and the Xbox 360. It connects via an ethernet cord to the back of your Xbox or Xbox 360, then transmits wirelessly to your wireless router. It qualifies for free shipping too at Buy.com...
