Intermittent BT Issues
OS: Win 11 25H2 with latest updates
BT: Intel Wifi 6E AX211 (it's some combo chip) BT Driver ver: 24.40.0.3 (latest available per Intel's site)
Xbox Controller Firmware: 5.23.6 (latest per the Xbox Accessories app)
I use an Xbox Series controller via BT on my PC and I have an issue where sometimes the light on the controller is still on and solid, but nothing I do will have any action in the game. I have to do something like remove a battery to shut the controller off and then reconnect, after which it works fine. If I Win+Tab out of the game and see if I can get any kind of response from the controller elsewhere, I don't. It's like the controller has shut off, but the "X" light is still on.
There doesn't seem to be any particular rhyme or reason to why or when this will happen. I might be playing for 2-3+ hours with no problem, only to set the controller down to go use the restroom and come back 2-3 minutes later to an unresponsive controller. A few times it has happened while I'm playing a game. There are days where it may not happen at all, though it usually happens at least once a day, but rarely more than that.
The controller is probably never more than about 6ft from my computer and the only other BT devices around are my phone, some airpods, and a google home device, none of which are actively using BT while I'm gaming. There may be a few other devices, but they'd be on another floor. Aside from my desk, which is maybe an inch thick, there's nothing obstructing the line of sight from controller to PC either. Aside from these momentary hiccups the controller works exactly as expected.
I've tried removing the controller from the BT settings and redoing it, updating the drivers, rolling the drivers back to the latest from the system OEM as opposed to Intel. Haven't had any luck. I have another BT controller, 3rd party. It doesn't suffer from the disconnects like the official Xbox controller, but it will sometimes stutter with actions becoming sluggish or delayed for a few seconds and then it magically clears up and works fine again.
Just looking for any suggestions on 1) what may be causing this, and 2) what I might do to resolve it.
