Why does my xbox 360 not connect to the internet? I am having problems connecting to my network with my xbox 360. The other 3 computers in my house have no problems connecting to the internet. The cable I am using for the xbox 360 to connect it to the modem works with the computer, but not the xbox 360. It worked with the xbox 360 a few months ago, though. If someone could help me, It would be very much appreciated.
