Right, I have a question before I have to just go and buy the wireless adapter. I have a couple of PCs in the house. The ground PC is set up with a wireless router. My PC is upstairs and has a Wireless USB adapter. Is there anyway I can connect the PC upstairs to my 360 via ethernet (crossover) and use the wireless adapter on my PC as the 360 access point? Is that's not possible, can I use any 3rd party wireless adapter with the 360 or does it have to be the expensive official one?
