How to Fix Bluetooth Not Working on Windows 11
Bluetooth problems on Windows 11 can look very different: headphones will not pair, a mouse repeatedly disconnects, or the Bluetooth switch disappears altogether. Start with the symptom you actually have instead of changing every setting at once.
This guide follows Microsoft's troubleshooting guidance and separates connection problems from missing hardware and audio-output issues. Try one change, test the same device again, and continue only if the problem remains.
Bluetooth Fixes at a Glance
| Problem | First check |
|---|---|
| Device will not pair | Pairing mode, battery and distance |
| Bluetooth switch missing | Hardware support and adapter detection |
| Headphones connect without sound | Selected audio output and volume |
| Connection repeatedly drops | Power settings and Bluetooth driver |
| Problem started after an update | Driver update or available rollback |
1. Check Bluetooth and Your Accessory
Open Settings > Bluetooth & devices and turn Bluetooth on. Confirm that your PC actually supports Bluetooth, particularly on a desktop without a built-in wireless adapter.
Charge the accessory, switch it on and move it closer to the computer. Follow its manual to enter pairing mode; being powered on alone does not mean it is ready to pair.
If the device is absent from the discovery list, check Settings > Bluetooth & devices > Devices. Where available, change Bluetooth devices discovery to Advanced. Microsoft also notes that some unshielded USB devices connected to USB 3.0 ports can interfere with Bluetooth.
2. Run the Bluetooth Troubleshooter
Microsoft recommends the automated troubleshooter in Get Help for Windows 11. Open Get Help from Start, search for Bluetooth troubleshooting and follow its prompts. You can also use the troubleshooter link in Microsoft's Bluetooth support guide.
Record any error it reports. That result is more useful for the next step than repeatedly running the same check.
3. Remove and Pair the Device Again
If Bluetooth is available but one accessory will not connect, recreate its pairing:
- Open Settings > Bluetooth & devices.
- Find the accessory, open its three-dot menu and choose Remove device.
- Put the accessory back into pairing mode.
- Select Add device > Bluetooth and choose it when it appears.
You can also switch Bluetooth off, wait about 10 seconds and switch it on again. Restart the PC and accessory if pairing still fails. These steps follow Microsoft's connection troubleshooting guidance.
Removing a device means you must pair it again. If it is your only mouse or keyboard, arrange another way to control the PC first.
4. Update or Roll Back the Bluetooth Driver
Open Device Manager, expand Bluetooth and right-click the Bluetooth adapter. Choose Update driver > Search automatically for drivers, then restart if required.
Also check Settings > Windows Update > Check for updates. If Windows cannot find a newer driver, use your PC manufacturer's support page and select the package for your exact model and Windows 11.
If the problem began immediately after a driver update, open the adapter's Properties > Driver tab and try Roll Back Driver if available.
As a later step, Microsoft describes uninstalling the adapter and restarting to reinstall its driver. Have the manufacturer's driver package and an alternative input method ready before doing this. Avoid removing unrelated devices.
5. Restore a Missing Bluetooth Switch
If the switch is missing or greyed out, Windows may not be detecting or enabling the adapter. Turn Airplane mode off, then try the complete shutdown procedure in Microsoft's missing Bluetooth guide:
- Save your work.
- Hold Shift while selecting Start > Power > Shut down.
- Wait one minute after the PC turns off.
- Turn it back on and check Bluetooth again.
If the adapter remains absent, confirm the computer's specifications and contact its manufacturer. A settings change cannot add Bluetooth hardware to a computer that does not have it.
6. Fix Connected Headphones with No Sound
A connected headset is not necessarily the selected playback device. Open Settings > System > Sound and choose the Bluetooth headphones under Output. Check the Windows volume and the headset's own volume, then test playback.
If sound still does not work, remove and re-pair the headphones, then check the adapter driver. Microsoft's Bluetooth audio guide also covers device compatibility and audio settings.
Describe the remaining symptom precisely: silence, distorted sound and repeated disconnections call for different checks.
7. Stop Repeated Bluetooth Disconnections
For connections that drop, temporarily turn off Energy saver and test again. In Device Manager, open the Bluetooth adapter's Properties. If a Power Management tab exists, clear Allow the computer to turn off this device to save power. Skip this adjustment if the tab is absent.
Microsoft's disconnection guide also suggests restarting Bluetooth Support Service: press Windows + R, enter services.msc, find the service and choose Restart where available. Connected accessories may disconnect briefly.
Change one setting at a time. If disabling power saving makes no difference, restore your previous preference.
When to Get Hardware Support
Keep a short record of the accessory model, adapter name, error messages and steps already tried. If hardware remains undetected or the fault persists, share that record with the PC or accessory manufacturer.

Frequently Asked Questions
Why Is Bluetooth Missing from Windows 11?
Check whether the PC has Bluetooth hardware and whether Windows detects its adapter. Driver or hardware problems can prevent the switch from appearing.
Why Do My Headphones Connect but Play No Sound?
Check the selected output in Sound settings and both volume controls before changing drivers.
Should I Reset Windows to Fix Bluetooth?
Try the targeted checks above first. A full reset is a much broader change than reconnecting an accessory or correcting its driver.
