Bluetooth losing and regaining connection (Wireless AC 9560)

My machine intermittently drops Bluetooth connections. It happens every time after startup: my Bluetooth mouse initially works, then stops working for about a minute, then it starts working again.

 

Sometimes during a Zoom call both the mouse and my Bluetooth headset stop working. They usually recover eventually, but sometimes I need to restart my machine to make them work again.

 

Nothing obvious is visible in system logs. I have the latest Bluetooth drivers and Windows patches. Here is the output from the System Support Utility:

Any ideas?

Hello KZado, 

  

 

Thank you for posting on the Intel® communities.   

  

 

In order to better assist you, please provide the following:  

 

  

 

1. Run the Intel® System Support Utility (Intel® SSU) to gather more details about the system. 

 

· Download the Intel® SSU and save the application on your computer: https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility-for-Windows-  

 

· Open the application, check the "Everything" checkbox, and click "Scan" to see the system and device information. The Intel® SSU defaults to the "Summary View" on the output screen following the scan. Click the menu where it says "Summary" to change to "Detailed View".  

 

· To save your scan, click Next and click Save.  

 

2. Is this issue recent? If so, when did it start?

 

3. Are you experiencing Wi-Fi issues?

 

4. Have you tried with the drivers from the laptop manufacturer?

 

5. Do you see an error code or yellow mark at the device manager?

 

 

 

 

 

Best regards,

Deivid, thanks for the reply

 

1. I am a bit reluctant to share the  whole result of SSU Everything/Detailed scan because it has a bunch of PII in the logs. If there is something specific that you want me to check, I can definitively share.

2. The issue has started about a couple of months ago. Possibly it was related to one of the OS updates, I am not certain.

3.  No WiFi issues observed.

4. The drivers I am running are the latest Lenovo has for my machine.

5. I have seen "This Device Cannot Start (Code 10) – STATUS_DEVICE_POWER_FAILURE" error literally just once (associated with Intel Wireless Bluetooth device). That went away after system restart. Other than that I do not see any errors in Device Manager. Bluetooth just stops working for a minute, then it "fixes" itself. Usually the machine goes through this cycle just once, shortly after system startup and logging in. Sometimes it happens several (2-3) times in a row.

 

Question for you: is there a setting that would turn on more verbose logging for the Intel Bluetooth driver?

Hello KZado, 



Based on the information provided, I would like you to try the following:


1. Clean installation of Intel drivers:

- Driver: https://downloadcenter.intel.com/download/30326/Intel-Wireless-Bluetooth-for-Windows-10

- Steps: https://www.intel.com/content/www/us/en/support/articles/000022173/wireless/intel-wireless-gigabit-p...


2. Rollback Windows version.


3. Check for a BIOS update.


4. Try reinstalling Windows.


5. If none of the previous steps worked, contact Lenovo for further steps.

Deivid, I did clean driver installation and checked for BIOS updates. These did not help.

 

Honestly, reinstallation of Windows is not possible for me currently; it would be too disruptive for my work. I can live with the problem now and hope that one of the future updates to the drivers and/or BIOS/chipset/Windows OS will solve it for good. 

 

Appreciate the follow-up. Cheers!

Hello KZado, 



I do appreciate the update. I understand that you can not reinstall Windows at this moment, this could be quite complicated with laptops. 


The best thing to do at this point would be to get in contact with the laptop manufacturer and check for further instructions or check the warranty options.



Please keep in mind that this thread will no longer be monitored by Intel.

I was able to finally find a workaround for this issue:

  1. Open Device Manager
  2. Expand "Universal Serial Bus controllers" node
  3. For every "USB Root Hub" device (there might be more than one), open Properties, then go to "Power Management" tab and uncheck "Allow the computer to turn off this device to save power" option. Do this for every USB Root Hub device.

This seems to take care of this problem on my machine. Tested with both Windows 10 and Windows 11. Hope this helps someone.
