I really want XBOX Live but I don’t know what I need to get it. I already have 360 but I don’t have WiFi. I’ve been told just to get an ethernet cable that connects from the computer to the back of the XBOX and the membership card. All I need to know is if the ethernet cable is all I need and if it would work. If not, what do I need in order to connect to XBOX live? Thanks for your help.
