Hi I have a sprint internet wireless card and I want to play my xbox360 online do I need a usb cord to get started or can I just plug in my intertnet card and go from there?

The Xbox 360 needs its own special woreless unit Like this one (http://www.game.co.uk/Xbox360/Hardware/Accessory/~r327033/Xbox-360-Wireless-Adapter/). I'm afraid a normal wireess USB Dongle won't work. You could use a standard network cable to go from your router to the xbox, that's the cheapest way to get online.

I suggest ethernet cable from router to xbox 360... that's set up I have and it works great the wireless adapter will set you back £60
