Is there a way to connect my wireless Xbox 360 controller to my computer without using a cord? Maybe with a wireless network card or wireless internet usb adapter?
There is no way to connect a wireless xbox controller to a computer, not even with a charger wire as that only sends battery charge, not electrical signals. You'd need to use a wired controller.
You can buy a "Microsoft Wireless Receiver Adapter" if you want to connect your wireless computer to your PC. Anyway, why is this post in the contests and giveaways?
