tldr; W11 bluetooth doesn't work with multiple cards. It will see devices but will not pair. Same hw pairs under Linux.

hey folks. I posted this to /r/techsupport on reddit and for some reason they say they don't support Windows 11 Enterprise... and it took them a day to tell me instead of using automod. I thought this was both funny and the dumbest thing. Anyway, here's a fun little issue I'm trying to sort out.

Windows 11 Enterprise 22h2 (22621.3810)

About two weeks ago (after a year of having this system) my bluetooth decided not to pair with anything. It will see devices and try to pair, but it never goes through.

I have tried:

• a different wireless card / bt combo (PCIE)
• removing the wireless / bt combo and using a bt dongle
• removing all drivers (show hidden devices etc), rebooting clean, reinstalling
• changing the USB connection to the mobo for the PCIE card
• live boot of latest Ubuntu LTS -- successfully paired DS4 controller and Sony Headphones

The event logs for Bluetooth Policy are all positive (e.g. A connection to a remote device 0xA4538553B7FD was successfully established) -- but nothing is paired.

This happened on a day when I added two HDDs to the box and ran updates etc. I also tried everything above without the drives installed without any luck.

Any ideas?

notes:

• I just finished with a W11 windows-to-go install off a super slow USB and I wasn't able to pair headphones or the DS4, but I did pair some sony TW earbuds. I'm sensing a fresh install in my future.
