My bluetooth does not reconnect, or if it does, it is spotty, breaks up and pops. I spent a good hour working with chat to reinstall the bluetooth driver, and it failed again shortly there after. I am in Windows 11, which has given me multiple problems with bluetooth. This problem has been around for several years. Is there a chance MS will address it? If not, can you recommend a USB dongle that will work since MS does not? Below is a message from a customer two years ago.
Bluetooth stops working after system goes to sleep - Windows 11 Pro Whenever my system goes to sleep. My Bluetooth adapter stops working. But upon reboot, it works normally again. I've already disabled allowing the computer to turn off this device to save power as well as making sure I'm using the latest Intel drivers and the issue persists. The adapter I'm using is an Intel AX210 wireless card plugged in through PCI-E and into one of the USB headers in my MB. I know the header is not the issue because I've had water blocks plugged in before that had no issues being recognized after sleep. After checking device manager before and after sleep I've noticed that the Bluetooth hardware itself is STILL recognized by my system, but what disappears is the Microsoft Bluetooth Enumerators (LE and normal). Is this an issue with those virtual devices instead? I'm not sure how to troubleshoot from here. I've already tried all the Bluetooth and power troubleshooters before and after sleep.

I recently had the same issue, my BT dongle wont respond after the PC exits sleep mode, but works fine if the pc does a full shutdown. I did everything everyone always recommends, "turn off fast startup" and "USB power setting" nothing worked.
I finally fixed it by opening the services settings from task manager, and looked at "Bluetooth support service" and changed its startup type from "manual" to "automatic"
Hello, Eric Tucker
Welcome to the Microsoft Community.
Hello, thank you for your feedback here on your issue with Bluetooth devices failing to reconnect or behaving abnormally after resuming from sleep mode.
I will provide you with some potential solutions and also recommend some USB Bluetooth adapters as an alternative.
Make sure your Bluetooth drivers are up to date. Usually, Windows Update does not always provide the latest drivers. You can download the latest driver directly from the manufacturer's website (e.g. Intel Bluetooth adapters need to be updated from Intel's official website, Realtek Bluetooth adapters need to be updated from Realtek's official website).
You've already mentioned disabling the “Allow the computer to turn off this device to save power” option, but it's still recommended to double-check all settings related to power management:
Device Manager: Go to Device Manager > Bluetooth > [your Bluetooth adapter], right click, select “Properties” > “Power Management” tab, make sure “Allow computer to turn off this device to save power” is unchecked. “is unchecked.
Power Plan Settings: In Control Panel > Power Options, make sure your power plan settings do not allow USB or Bluetooth to save power while hibernating.
Fast startup sometimes causes the peripherals to not work properly after resuming from sleep mode. You can try to disable it:
Go to Control Panel > Power Options > Select the function of the power button.
Click Change currently unavailable settings.
Uncheck Enable fast startup (recommended).
Even after reinstalling the driver, the problem may still persist due to corrupt settings. In Device Manager, right-click on your Bluetooth device and select Uninstall Device, then restart your computer. After restarting, Windows should automatically reinstall the Bluetooth driver. If it doesn't install automatically, you can install it manually.
In some cases, modifying specific registry settings can help resolve hardware initialization issues after resuming hibernation. However, modifying the registry should be done carefully to avoid improper modifications affecting system stability. Some users are advised to modify registry entries related to power management, such as HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters.
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.
Some users have found that updating the BIOS or UEFI firmware solves the problem of hardware not re-initializing correctly after sleep. If you are using a PCI-E Bluetooth card or USB Bluetooth adapter, you can visit the motherboard manufacturer's official website to see if there is a relevant firmware update.
If Microsoft and driver updates can't solve the problem, you can consider using an external USB Bluetooth adapter to bypass the built-in Bluetooth adapter. Here are some common and Windows 11 compatible USB Bluetooth adapter brands:
TP-Link, Plugable, ASUS, Avantree and other brands are good choices
These USB adapters are usually plug-and-play, so they should be able to fix the problem easily. Simply disable the built-in Bluetooth adapter in Device Manager (if possible) to avoid conflicts with external adapters.
