I was using my bluetooth headphones yesterday and everything was working fine. When I returned to my computer, which was still on with everything unchanged, the bluetooth function no longer worked. I've tried everything I could find online but nothing has worked. When attempting to connect to Bluetooth, the computer says to turn bluetooth on. There is no option to turn bluetooth on. Under device manager, there is the Qualcomm QCA9377 Bluetooth item. It often says "Windows has stopped this device because it has reported problems. (Code 43)", but disabling it as well as uninstalling and reinstalling it have both failed. I tried both downloading it from microsoft and from the manufacturer (Dell) and both have failed consistently with multiple attempts. Troubleshooting the bluetooth feature sometimes yields "bluetooth drivers have failed", but ALWAYS yields "Bluetooth Radio Status - Not Fixed". I have restarted and shut down countless times. I have used the task manager to manually start every bluetooth process but there have been no results. I know there are other threads like this but not a single one has a working solution of any kind, and most of the threads die out before the issue is resolved. Has anyone ever found a solution to this issue? Update: I have also rolled back the driver of the Qualcomm network adapter multiple times, with no effect.

In a twisted way turning the power off removing the power cord, waiting 5 minutes, plugging it back in makes sense. The motherboard never really looses power unless you unplug it (even then there is a battery for the clock.) Unplugging the computer may be the only way to completely reset the bluetooth hardware. Or buy a bluetooth 5.0 Dongle for $15.00.

The common solution. "Power down and restart" seems to work BUT we have yet to see or hear of an actual solution to this. Is this symptomatic of flakey Qualcomm bluetooth hardware, Incompatible BIOS Firmware, or software drivers? Windows spins up and Bluetooth is gone. Remove all power sources, hard shut down, bring it back up and Bluetooth reappears. Works for a while then the problem reoccurs. The only consistent thing I have noticed is the PC Manufacturer, Qualcomm, and the Driver guys all seem to avoid engaging or resolving this issue. Seems like a bad case of not my problem.

Exactly the same issue with Wyze Headphones and @zebra75 fixed it for me. Power down. Unplug power for at least thirty seconds. Plug in and power up. Bluetooth reestablished. Thanks!

Had performed a Windows update a couple of days ago. Shortly after during a MS Teams business call, my Bluetooth headset stopped working which is a known issue on the Dell laptops. I usually have to re-establish the Bluetooth connection but this time the Bluetooth was turned off and could not turn it back on as it was greyed out. Laptop reboot didn't fix it. Couldn't delete BT device. Couldn't add new BT device. Per posts on this thread, I powered off laptop and disconnected power cable for 5 minutes. Afterwards, turned on laptop and Bluetooth is now enabled and working. Hopefully, it sticks. Can't have this reoccurring again especially during work hours.

Powering off and pulling the power on my Dell Inspiron laptop worked as well. I did have to delete the failed USB entry and then rediscover, but this worked. Thanks for posting. Not exactly sure why a power off and more importantly pulling the power WHICH IS THE ACTUAL step that worked for me, since I tried just powering off first and that didn't help, fixes the issue though.
