Uninstalling the WIDCOMM Bluetooth Software and rebooting fixed the issue for good. I searched 'bluetooth' in installed programs for drivers and I had two different ones installed as listed bow. Previously I did installed the new driver (find service tag of Dell system and took latest available driver from dell) but that alone didn't fix the issue.Īnother suggestion I can give you is if you can somehow force this dialog (posted above) to come and selected `Allow bluetooth devices to find this PC' (this was the deselected when the dialog came up), that seems to apply the proper settings too perhaps. Now I got back to windows settings and I can see the bluetooth switch (enable/disable) option! I connected Bluetooth speak and it works! I repeated uninstalled them several times but on 3rd time, the refreshing stopped and out of no where I got this screen as well. I uninstalled them all but they will come back when scan for new devices.

There were several items listed under blutooth (previously connected device). I had the show hidden devices option enabled from view menu. When I scanned for new devices, the bluetooth driver automatically got installed and refreshing problem appeared as well. When I uninstalled the bluetooth device, the refreshing stopped. I figured I should perhaps fix that first and following up, it indeed was connected with bluetooth driver. I noticed I had another issue too that when I go into device manager, I was constantly refreshing after every little while. I had installed a USB bluetooth dongle as well after the fact which I have lost and it seemed a mashup. I had tried everything and I thought it will never work but finally got it to work! PS.: Both adapters are Intel 7620 AC and 1030 N. I haven't tried that, but this might also be worth a shot. Maybe it is also enough to remove the adapter startup Windows, shut it down and put in the adapter again.

So if you have a second one lying around and don't want to tinker with software methods which probably won't work if you your adapter disappeared in the device manager try this out. Another thing to note is that a driver update of either the WLAN or Bluetooth broke the Bluetooth functionality. This seems to be a bug within Windows 10 because I'm pretty sure this wasn't a connection issue since the WLAN worked flawlessly. I tried most of the above listed suggestions but none did help or brought it back to life. The switch for turning on Bluetooth was showing up again and it was also listed in the device manager. So I disabled Bluetooth, turned of the computer and switched my other one (previously not working) back in and it started immediately working again.

Strangly for me it did with my old adapter as soon as I booted into Windows again. Another thing to consider, if you have a spare WLAN adapter / card for your laptop.
