trouble connecting to xbox live wirelessly. was wandering if I bought a cable modem and hooked xbox to that would it work if it was the second modem. call rip-off house i mean bright house and they said i would have to pay $45 extra a month for another high speed internet connection. bump that. why cant i go buy my own modem and put a splitter in my cable line and hook it up that way? any light on the subject would be awesome.
