Windows 10: Bluetooth keeps disappearing, Windows 11

For the last few weeks, every now and then my Bluetooth settings completely disappears, disconnecting my mouse & headphones. I have a Dell laptop with the latest Bluetooth driver installed. Restarting my laptop brings it back temporarily but it inevitably disconnects again at random.Things I've tried that haven't worked, that I've seen on posts from people with similar issues:-Booting in safe mode-Running troubleshooter; it says it can't diagnose the problem-Setting Bluetooth to automatic under services.msc-Run health scans through command prompt-Turned off fast start up, powered off the l

Bluetooth disappeared (Windows 11)

• So uninstalled the Bluetooth Adapter and the faulty USB device and rebooted.
  
• Bluetooth Capability Restored!!
  

Yes - this worked on my Acer Desktop which I upgraded to Windows 11 some time ago. Bluetooth disappeared / hid itself after a Wondows update. Anyway - your advice as above has fixed the problem. Hope it holds. Many thanks.

 

Bluetooth disappeared (Windows 11)

I've just had this problem....twice now!! Essentially, with no warning or error, a perfectly working Bluetooth setup suddenly disappears the follow time the PC is booted up. Both occasions appear to occur after a WIndows Update.

My system is a fairly new Dell Inspiron 3881 (10th Gen) i7 Desktop, running Windows 11.

The 1st time this happened was after the Windows 10 > 11 upgrade via Windows Update. After the reboot..no Bluetooth. I checked the available Network Connections spotted the Bluetooth Network Connection as "Not enabled", I noticed the Device Manager had no Bluetooth hardware listed. So I simply re-download the Qualcomm Bluetooth adapter driver from the Dell website and all capability returned after a reboot.

The 2nd time was a little more involved. A "cumulative update" was installed yesterday via Windows Update, no reboot required and no effect on Bluetooth Capabilities. But this morning, booted up PC, no Bluetooth:

• After trying a few things suggested in this thread nothing worked.
  
• Checking Network connection revealed no Bluetooth connection this time (disabled or otherwise).
  
• Device Manager also showed no Bluetooth hardware. I did notice a faulty USB device down in the USB list (listed as unknown as description request failed, so no Hardware ID or any means to identify what this is). I did note the location though. Status of "disabled as Windows has found a problem with this device".
  
• Device Manager showed Bluetooth hardware after unhiding. All listed Bluetooth devices were all "grayed" (this includes all the (Bluetooth) connected devices). I located the actual Bluetooth Adapter and looked up its properties; Status of "This device is not connected to this computer". I also noticed the Device Location as exactly the same as the Faulty USB device.
  
• So uninstalled the Bluetooth Adapter and the faulty USB device and rebooted.
  
• Bluetooth Capability Restored!!
  

 

Bluetooth Keeps Disappearing From Settings ??


Hey guys looking for some help with my Acer E1-531 Windows 10 laptop.

The issue i'm having is my bluetooth keeps disappearing from my laptop. I use a bluetooth speaker and every few restarts all my bluetooth settings just disappear. When ever i try to search "Bluetooth" all that comes up is "Airplane Mode".

I spoke with Acer tech support and they recommended i re-install windows so i did and that worked but now a week later i'm having the same problem. I even tried installing drivers from the Acer site and after it's downloaded i still can't find anything bluetooth related.

Any help would be appreciated, thanks alot.
