Wireless Adapter
 

I want to make my xbox 360's internet connecttion wireless, but i dont want to buy the microsoft one becuase it is too expensive. If I bought a netgear one and put it in the back of my xbox 360 would it work? It seems pointless to pay 100 dollars for the microsoft adapter when i can buy a netgear one for half the price.

I tried this, I couldnt get the 360 couldnt detect the wireless adapter.

USB adapters don't work. You would need an Ethernet wireless adapter or some kind of access point. I think you can find the original xbox wireless adapter for $30 or so bucks. Any access point should be fine.
