Common Causes

Before you begin: Ensure your Bluetooth device is charged, turned on, and in pairing mode. Many issues after a Windows update are caused by the device being forgotten or the Bluetooth radio being disabled.

Quick Fix Steps

Start with these fast checks. They resolve most Bluetooth pairing problems after a Windows 11 update.

Toggle Bluetooth off and on: Go to Settings > Bluetooth & devices, switch Bluetooth off, wait 10 seconds, then switch it back on.
Restart your computer. A full restart (not shutdown) clears temporary driver states.
Check that Airplane mode is off. Go to Settings > Network & internet > Airplane mode.
Move the Bluetooth device within 1 metre of your PC and remove any physical obstructions.

Detailed Instructions

Step 1: Run the Bluetooth troubleshooter

Windows 11 includes a built-in diagnostic tool that can automatically detect and fix common Bluetooth problems.

Open Settings by pressing Windows key + I.
Go to System > Troubleshoot > Other troubleshooters.
Find Bluetooth in the list and click Run.
Follow the on-screen prompts. If the troubleshooter finds issues, apply the recommended fixes.
Restart your computer and test pairing again.

Step 2: Reinstall or roll back the Bluetooth driver

A Windows update can install a driver that is incompatible with your Bluetooth adapter. Rolling back or reinstalling the driver often resolves this.

Right-click the Start button and select Device Manager.
Expand the Bluetooth section.
Right-click your Bluetooth adapter (it may be named Intel Wireless Bluetooth, Realtek Bluetooth Adapter, or similar) and select Properties.
Open the Driver tab.
If the Roll Back Driver button is available, click it and follow the prompts. This restores the previous driver version.
If rollback is not available, click Uninstall Device. Tick Attempt to remove the driver for this device and click Uninstall.
Restart your computer. Windows will automatically reinstall the Bluetooth driver.
Test pairing after the restart.

Important: If you uninstall the driver and Windows does not reinstall it automatically, you will need to download the latest driver from your PC or motherboard manufacturer’s website. Do not download drivers from third-party sources.

Step 3: Remove and re-pair the Bluetooth device

After an update, Windows may retain a corrupted pairing record. Removing the device and pairing it again creates a fresh connection profile.

Go to Settings > Bluetooth & devices > Devices.
Find the problematic device in the list.
Click the three-dot menu next to the device name and select Remove device.
Confirm by clicking Yes.
Restart your computer.
Put your Bluetooth device into pairing mode (refer to the device’s manual for the correct method).
In Windows, go to Settings > Bluetooth & devices and click Add device.
Select Bluetooth and choose your device from the list.
Follow any on-screen pairing prompts.

Step 4: Restart Bluetooth support services

Windows runs several background services that manage Bluetooth connectivity. Restarting them can clear stuck states.

Press Windows key + R, type services.msc, and press Enter.
Locate Bluetooth Support Service in the list.
Right-click it and select Restart. If Restart is greyed out, select Start.
Locate Bluetooth User Support Service and repeat the same process.
Close the Services window and test pairing.

Step 5: Check for additional Windows updates

Microsoft frequently releases patches that fix Bluetooth bugs introduced by earlier updates.

Go to Settings > Windows Update.
Click Check for updates.
Install any available updates, including optional driver updates.
Restart your computer after installation completes.
Test Bluetooth pairing again.

Tip: You can also check for optional driver updates by going to Settings > Windows Update > Advanced options > Optional updates. Bluetooth driver updates often appear here.

Troubleshooting Specific Scenarios

Bluetooth toggle is missing or greyed out

If the Bluetooth toggle is missing from Settings, the Bluetooth adapter may be disabled in Device Manager or the BIOS.

Open Device Manager and expand Bluetooth.
If the adapter shows a down arrow, right-click it and select Enable device.
If the adapter does not appear at all, click View > Show hidden devices.
If it still does not appear, restart your computer and enter the BIOS/UEFI settings. Ensure the Bluetooth or wireless radio is enabled.

Device appears but fails to connect

If your device shows in the list but the connection fails or drops immediately:

Ensure the device is not already connected to another computer or phone. Many Bluetooth devices only support one active connection at a time.
Turn the device off and on again, then retry pairing.
Check for interference from USB 3.0 devices, Wi-Fi routers, or microwave ovens. Move the Bluetooth device and PC away from these sources.
Update the Bluetooth device’s firmware using the manufacturer’s app or website.

Audio devices pair but no sound plays

If a Bluetooth headset or speaker pairs successfully but produces no audio:

Go to Settings > System > Sound.
Under Output, ensure your Bluetooth device is selected as the default output device.
Click the device name and check that Audio is enabled under Device usage.
Disconnect and reconnect the device.
