erm, well i don't quite understand your needs but i am thinking like you want to make your xbox wireless is that correct?.. without having to connect to pc through cables or shit?... and to be able to communicate wirelessly with the pc ...
if that is what u want, then try this product from d-link, it supports older standards of 802.11b but i guess it's adequate although certainly not as fast as cable connection
Ethernet to Wireless Bridge Dlink
