Hmmm, my xbox will be downstairs, and my completely wired laptop is upstairs, and I would like to connect my xbox to my computer so i can “download to xbox 360” from the xbox.com marketplace. I originally thought that the 360 ethernet cable was usb on one end, and that i could just plug the ethernet side to the 360 and the usb side into my computer. I looked it up and apparently it’s an ethernet port on both ends. Do I have to connect my xbox to the modem directly and use the xbox for that stuff? Or is there another way? I just want to download some movies and free map packs+demos and that sort of stuff.
