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.

Uninstalling the malfunctioning USB driver and then restarting (unplugged) worked for me! Restarting alone didn't do anything. For people who end up reading this, look into the USB drivers like in Allan's post. Took me hours and hours to find it but that was the fix for me. Also restarting took much longer while the bluetooth device wasn't working, it seems like the computer tried to install the drivers but failed (making restart take longer as drivers are installed on boot) and ending up with the unknown USB device driver.

Thank you all so much for the positive feedback on this fix. It was the first post I have ever done and I was surprised how many people this has helped out. I'm glad its worked out for everyone. Thanks again

Don't even understand it, but so happy it worked. Turning off the computer, unplugging it for 5 minutes, and plugging it back in worked! Hours were spent on this issue, and for some reason fixing it made me laugh due to how oddly simple it was, but it was something I would have probably never thought to do. Thank you!!

I, too, had my Bluetooth Icon suddenly disappear. I cannot tell you how many times I Uninstalled driver, Reinstalled driver, Restarted PC..... then today I lucked up on this page. Sure enough, I shut my PC down and unplugged the power cable for a few minutes; booted back up and Hallelujah! Bluetooth icon has returned in Control Center and now I once again have my AirPods back in action. OMG! Thank you for this easy fix. Wish I had known this two days ago. :)

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.
