They make adapter to network the xbox to a PC

Then you either get a wireless router and come from the cable modem to the router and then to the pc and the wireless signal goes to the xboz adapter.
or you MIGHT be able to just get a wireless adapter for the computer and it will be able to talk to the xbox wireless adapter in whats called "ad hoc" mode.

and they probably also make "wired" adapter where you would either hook to a router or just have it go to a second netwrok card in the pc.
