Controller connection

So recently my Xbox wasn’t connecting to the internet at all. The servers weren’t shut down, the Xbox would just not connect to the wifi. The Xbox gave me a notification that it had to do with a problem with the connection of the controller. The
controller would have to be restarted and connect to the wifi. It restarted the controller but it wouldn’t connect to the Xbox. I tried syncing the controller like when I first got it, I tried other controllers, and I even tried using a cable to connect the
controller to the Xbox, yet it still won’t connect.

Other controllers works?

All controller don't connect/work? Or only one? (maybe your preferred controller)

Check these support links for a solution:

Connect the Xbox Adaptive Controller to Xbox One

Connect the Xbox Adaptive Controller to a PC

Updates:

Paired both controllers to console at the same time. Both controllers lost and regain sync at the same time.

Paired Elite controller to iPhone. No disconnects.

Paired one controller to console and other to phone. Controller connected to console disconnected, controller connected to iPhone stayed connected.

If you cannot connect controllers, use several different cords to connect the controller to the Xbox, make sure there is a usb type connector at the bed of the cord that is connected to the controller, and then go to settIngs and then accessories, click
on the controller, and then see if it needs any updates or connect it to your account

Have you tried connecting headset to controller with a headset adapter connected to controller. The adapter has volume controls on it.
