I have an xbit set up and working on my computer, but did not set it up myself. I am trying to set up a network so I can exchange files between my pc and xbox. I have an ethernetcard and ethernet cable. When I connect my xbox to my computer, though, my connection says that a network cable is unplugged. Do I need a program to set up a network? I put in the whole 192.168.etc., but I don't know what to do from there. Need help bad!
