where can i buy wireless gaming receiver for xbox360?

i searched online but i can't find one. i need it for my games.

 

What are you looking for exactly? You want the wifi adapter for the 360, so you can go online without using a cable?

 

no, i want one for connecting a 360 controller so i can use it to play games like the last remnant

 

The 360 already connects wirelessly

 

for pc.

I don't think it's sold new anymore, since Microsoft sells the Xbox controller for Windows.
