I have tried many ways from internet such as run troubleshoot, reinstall Bluetooth driver, etc. but it still not worked. Then I tried to reset my windows. Unfortunately, it can't reset by ishowed "no changes were made". After that I tried run startup repair, but I still cannot do that. Finally, I download new windows 11 ios file and reinstall it. After I installed new windows every problems is still not solved. my bluetooth still lost and also can't reset it agian or run star

I don't have any bluetooth devices but windows turned it on!!

1. I have no bluetooth devices in devices manager.
2,3,4. they all turned off before.

reboot or shutdown doesn't solved it.
i have USB wireless Mouse/Keyborad. i plug it out and use PS/2 but nothing.
i used DISM to repair image.

i tried everything but its not make any changes and windows still showing Bluetooth turned on.
a few days ago it was not even showing Bluetooth in Action Center but i don't understand what happened, no devices added or changed in my PC, no software Installed or Uninstalled, not a single Settings Changed in Windows or BIOS!!!

 

I don't have any bluetooth devices but windows turned it on!!


Then if they are still on, try some of these steps listed below, Not all of these steps may not apply, but, step #2 and #4 should help. I have all 4 steps on myself.

1 Go to Device manager and DISABLE Bluetooth, Do Not remove!
2 Turn USB suspend off
3 Set Hard Drive or SSD to Never
4 Turn Link State Power Management off
Settings 2 thur 4 can be found in your Power Management Settings.
Then click on "Change settings that are currently unavailable"
Then Reboot your Computer. This does work, may come back if you shut OFF your computer,then turn it back on, if it does, just a reboot will turn it off again.

 

Bluetooth Device is removed from Network Adapters when Bluetooth is turned on - Windows 11

I have a new laptop with Windows 11, and the behavior for the Bluetooth Network Adapter is not behaving as expected.

The issue is:

"In order to disable the Bluetooth Device from the Device Manager, the Bluetooth needs to be turned OFF to display the device in the list of Network Adapter."

Is this a bug?

On the Windows 11 system I have, the Bluetooth Device will only display in the list of Network Adapters when the Bluetooth Device is ENABLED and OFF.

The Bluetooth option was working correctly, the Bluetooth option is available in the Settings and turned ON.

When I opened the Device Manager, the Bluetooth Device was not listed in the Device Manager under Network Adapters.

The Bluetooth option is still available in the Settings allowing me to change the Bluetooth OFF and ON.

When I go to the Settings and turn the Bluetooth OFF, the Device Manager is updated and the Bluetooth Device is now displayed in the list of Network Adapters.

If I return to the Settings and turn the Bluetooth ON, the Network Adapter for the Bluetooth Device is removed from the list of Network Adapters again.

This was not the behavior I expected. I get the same results using the Bluetooth ON/OFF or the Airplane Mode settings for the Bluetooth ON/OFF.

Basically, when the Bluetooth Device is ENABLED and ON, it is NOT displaying in the list of Adapters.

The Bluetooth needs to be ENABLED and OFF in order to locate the Network Adapter in the Device Manager.

The Bluetooth Device itself is working correctly; however the device is not listed in the Device Manager when it is ENABLED, ON, and working.

Is this a bug? This is only occurring on my Windows 11 laptop. The Windows 10 displays the Bluetooth Device in the Device Manager when it is ENABLED, and does not change if the Bluetooth Device is switched ON or OFF .

Thank you in Advance.
