My console will not sync any controllers the button is working wheni push sync the lights flash like it is trying to sync but the controller never syncs. I have tried four different controllers and none of them will sync up.
I just got back up and running. It turned out to be the rf board on the front of the console. I intially thought it was the wifi board also but after swapping wifi boards I still had same issue. Onve I replaced the rf board it worked great.
Sounds like you need a new wifi card, this is a relatively simple repair job. Follow this guide Xbox One Wi-Fi Board Replacement
