Windows 11 Bluetooth and WiFi have disappeared

Hi,

I have an MSI P65 8RD running on Windows 11 22H2.

A few weeks ago, Bluetooth started having issues. The icon disappeared from the bottom tray and Bluetooth only connects with my mouse. I cannot make it connect with Bluetooth headphones it had been paired with. Bluetooth is not listed in the device manager (I checked hidden items). The Bluetooth support service is however running.

And last week, I lost the WiFi icon and connectivity. The Intel wireless AC 9560 adapter is listed in the device manager, but cannot start (code 10). Disabling and re-enabling for a few seconds appears to work, but ultimately results in the same failed operation. I tried updating the driver from Intel's website, but that didn't help. I do have ethernet connectivity. WiFi does appear in the device manager (but fails to function). In services, WLAN autoconfig is running, but I cannot get Wireless PAN DHCP server to start (error 1067 - process terminated unexpectedly).

Both Bluetooth and WiFi do NOT appear in regular settings.

Any suggestions?

Thanks,

Stijn

 

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!!
