Unable to use any Xbox 360 wireless adapters

I do apologize but the Xbox Elite does not have built in wireless. You would need to purchase a wireless adapter in order for the Xbox to be on the wifi connection. If you have a wireless adapter and are unable to connect please review the link I have provided
and let me know if you need any assistance with it.

The Xbox 360 controller, assuming you’re using wireless only charges via USB. You would need to get the now discontinued 360 wireless adapter

Any Xbox one controller will connect via USB, Bluetooth, or the Xbox wireless adapter. You need to use USB or the Xbox adapter for headset support

Incidentally, I checked on the page where one buys the receiver, and it says that it works for *any* wireless Xbox controller, so that shouldn't be the issue either.

Can you point us to the page so we can see which wireless adapter you bought?

Due to a change in the wireless protocol, Xbox 360 and Xbox One use a completely different "language" to talk wireless.

So unless a third party created a wireless receiver that can talk both protocols, I'm afraid the Xbox 360 controller will NOT work with a Xbox One compliant wireless adapter.

It might be, that the page says that you can use "any" Xbox One controller with the Adapter (e.g. standard wireless controllers, the Elite wireless controller, the wireless speed wheel, etc.), but you will NOT be able to use Xbox 360 accessories with a Xbox
One wireless adapter.

Hi Jamie,

Thank you for posting on the Xbox forums. I'd be happy to help.

Are you referring to the Xbox 360 wireless network adapter, or the Xbox 360 wireless receiver to connect controllers to a PC?

Either way any adapter made for the Xbox 360 can't be used on an Xbox One console.

Hello - the only USB wireless networking adapter that will work with the Xbox 360 is the official Xbox 360 Wireless Networking Adapter. Any other USB adapters will not work, as you can not install the drivers for them. You can use wireless adapters that
connect via an Ethernet cord, but for best performance we really recommend the official Wireless Networking Adapter. For more information, please check out:
