I just bought the DW4000 system and It runs off a send and recive modem, and a usb cord is ran from the modem to my computer. I was wondering how to hook my Xbox Live up so I can play, there are no enthernet cords used in my modem, or setup with my internet. I was thinking of just taking my enthernet cord and pluging it into the enthernet slot in the back of my computer, and then sharing that connection. Will that work? Thanks. I have not got the system hooked up yet, but I was just wondering what I would do when I'm ready to play.
