TL;DR: If you have Bluetooth not working on Windows 11, start with the quick checks: make sure Bluetooth and your accessory are on and charged, Airplane mode is off and the device is in pairing mode. Then toggle Bluetooth, remove and re-pair the device, run the Bluetooth troubleshooter, update or reinstall the Bluetooth driver in Device Manager and check that the Bluetooth Support Service is running. Most problems are fixed by re-pairing or a driver update. The steps below follow Microsoft’s own troubleshooting guidance.
Bluetooth problems on a Windows PC tend to show up in a few ways: the Bluetooth toggle is missing, your headphones will not pair, a mouse keeps disconnecting or audio connects but plays no sound. Whatever the symptom, when you find Bluetooth not working on Windows 11 the fix is usually one of a short list. Work through these steps in order, from quickest to most involved, and test your device after each one.
Quick checks before you start
These take under a minute and solve a surprising number of cases:
- Confirm your PC has Bluetooth. Microsoft notes that some devices simply do not have Bluetooth, so check the product specifications if the option is missing on a new PC.
- Check for a physical switch. Some laptops have a hardware Bluetooth or wireless switch on the body.
- Charge the accessory or replace its batteries, then turn it off and on again.
- Put the accessory in pairing mode. Many earbuds and speakers need a long press of a button; check the maker’s instructions.
- Move closer and away from unshielded USB 3.0 devices, which Microsoft says can interfere with Bluetooth connections.
9 fixes for Bluetooth not working on Windows 11
1. Make sure Bluetooth is on and Airplane mode is off
Select the Network, Sound or Battery icons on the right side of the taskbar to open Quick Settings. Turn on the Bluetooth tile and make sure the Airplane mode tile is off. You can also go to Start > Settings > Bluetooth & devices and check that Bluetooth is switched on.
2. Toggle Bluetooth off and on, then restart
In Settings > Bluetooth & devices, turn Bluetooth off, wait a few seconds and turn it back on. If that does not help, restart the PC. A full restart clears stuck driver states more reliably than sleep.
3. Remove the device and pair it again
Old pairing data is a common cause of connection failures. Go to Settings > Bluetooth & devices > Devices, select the three-dot menu next to the problem device and choose Remove device > Yes. Put the accessory back into pairing mode, then select Add device > Bluetooth and pick it from the list.
4. Change the Bluetooth device discovery setting
If your device never appears in the list, go to Settings > Bluetooth & devices > Devices and, under Device settings, set Bluetooth devices discovery to Advanced. Microsoft says the Default option shows common Bluetooth devices, while Advanced shows all types.
5. Run the Bluetooth troubleshooter
Windows 11 includes an automated troubleshooter in the Get Help app. You can also go to Start > Settings > System > Troubleshoot > Other troubleshooters and select Run next to Bluetooth. It checks common settings and services and tries to fix what it finds.
6. Update the Bluetooth driver
Microsoft calls an outdated or incompatible driver “one of the most common causes of Bluetooth connection problems,” especially after a Windows update. To update it:
- Search for Device Manager on the taskbar and open it.
- Expand Bluetooth and right-click your adapter (its name may include the word “radio”).
- Select Update driver > Search automatically for drivers, then restart if prompted.
If Windows finds nothing, download the latest Bluetooth driver from your PC or motherboard maker’s support site and install it. Also check Settings > Windows Update > Advanced options > Optional updates for driver updates.
7. Uninstall and reinstall the Bluetooth adapter
If the Bluetooth toggle has disappeared but the adapter still shows in Device Manager, right-click the adapter and choose Uninstall device. Shut down the PC (not just restart), wait a few seconds and turn it back on. Windows will try to reinstall the driver. If it does not, open Device Manager and select Action > Scan for hardware changes.
8. Check the Bluetooth Support Service
Windows relies on a background service for Bluetooth. Press Win + R, type services.msc and press Enter. Find Bluetooth Support Service, make sure it is running (right-click > Start if not) and consider setting its Startup type to Automatic. Restart the PC afterward.
9. Stop Windows from turning off the adapter to save power
On many laptops, power saving can switch off the Bluetooth adapter, causing random disconnects. In Device Manager, right-click the Bluetooth adapter, choose Properties and, if a Power Management tab appears, untick Allow the computer to turn off this device to save power. Not every adapter shows this tab.
Match the symptom to the fix
| Symptom | Try first |
|---|---|
| Bluetooth toggle missing | Fix 7 (reinstall adapter), Fix 6 (driver), Fix 8 (service) |
| Device not showing up | Pairing mode, Fix 4 (Advanced discovery), Fix 2 |
| Pairs but will not connect | Fix 3 (remove and re-pair), Fix 6 |
| Keeps disconnecting | Fix 9 (power saving), move away from USB 3.0 devices, Fix 6 |
| Stopped after a Windows update | Fix 6 (driver from PC maker), Fix 7 |
| Connected but no sound | Pick the device as output in Settings > System > Sound, then Fix 3 |
Connected but no sound?
If headphones show as connected but audio still plays from your speakers, go to Settings > System > Sound and choose the Bluetooth device under Output. You can also pick it from the arrow next to the volume slider in Quick Settings. Microsoft has a dedicated support article for Bluetooth audio issues linked from its main Bluetooth troubleshooting page.
When it might be hardware
If none of the fixes work, test the accessory on another phone or computer. If it works elsewhere, the problem is likely your PC’s adapter. A low-cost USB Bluetooth adapter is a common workaround for desktops or laptops with a faulty internal radio. If the accessory fails on every device, contact its manufacturer.

The bottom line
Bluetooth not working on Windows 11 is almost always fixable without special tools. Check the basics, re-pair the device, run the troubleshooter and update or reinstall the driver, in that order. If the Bluetooth option has vanished entirely, the driver and the Bluetooth Support Service are the usual suspects. And if the accessory fails everywhere, the problem is the gadget, not Windows.
