Bluetooth Not Working in Windows 11? 11 Ways to Fix It
Is Bluetooth not working in Windows 11? If the Bluetooth toggle has disappeared, your headphones won’t connect, your mouse keeps disconnecting, or Windows can’t find any Bluetooth devices, the problem could be caused by anything from a simple pairing issue to a faulty or missing driver.
The good news is that most Bluetooth problems can be investigated without replacing hardware.
The best approach is to first identify what Bluetooth is doing—or not doing—and then apply the appropriate fix.
Quick Answer: Why Is Bluetooth Not Working in Windows 11?
Bluetooth may stop working because it is turned off, the accessory isn’t in pairing mode, Windows has a temporary glitch, the Bluetooth driver is outdated or corrupted, the Bluetooth service isn’t running, power-management settings are interfering, or Windows cannot detect the Bluetooth adapter.
Microsoft recommends starting with its automated Bluetooth troubleshooter in the Get Help app, then checking Bluetooth settings, the device itself, drivers, Windows updates, and other system components.
First, identify your problem

1. Turn Bluetooth Off and Back On
Before changing drivers or system settings, reset the Bluetooth connection.
Press Windows + A to open Quick Settings and turn Bluetooth off. Wait about 10 seconds, then turn it back on.
You can also go to:
Settings → Bluetooth & devices
and switch Bluetooth off and on there.
Microsoft recommends toggling Bluetooth off, waiting briefly, and turning it back on when troubleshooting connection problems.
Also restart the Bluetooth accessory itself. If you’re using headphones, a mouse, keyboard, or speaker, turn it off, wait a few seconds, and turn it back on.
2. Make Sure Airplane Mode Is Off
Airplane mode can interfere with wireless connections.
Press Windows + A and check that Airplane mode is turned off.
Then confirm Bluetooth is enabled.
If you’re using a laptop with a physical wireless switch or a keyboard shortcut for wireless connectivity, check that as well. Microsoft notes that some computers have physical controls that can disable Bluetooth.
3. Check the Bluetooth Device and Pair It Again
If Bluetooth works but a particular device won’t connect, the problem may be with the accessory rather than Windows.
Check that the device:
- Is powered on
- Has sufficient battery
- Is within range
- Is actually in pairing mode
- Isn’t already connected to another device
If it still won’t connect, remove it from Windows and pair it again.
Go to:
Settings → Bluetooth & devices → Devices
Find the problem device, select the three-dot menu, and choose Remove device.
Then select Add device → Bluetooth and put the accessory into pairing mode.
Microsoft specifically recommends removing a device and adding it again when pairing information may be preventing a successful connection.
Quick test
If possible, try connecting a different Bluetooth device.
If your second device works, the original accessory is probably the problem.
If nothing connects, focus on Windows, the Bluetooth adapter, or the driver.
4. Run the Windows 11 Bluetooth Troubleshooter
Windows 11 includes an automated Bluetooth troubleshooter through the Get Help app.
Open Start and search for:
Bluetooth troubleshooter
Then follow the diagnostic steps provided by Get Help.
Microsoft currently recommends starting with the automated Bluetooth troubleshooter on Windows 11 because it can diagnose and attempt to correct common Bluetooth problems.
This is worth doing before manually changing advanced settings.
5. Restart Your PC
A simple restart can clear a temporary Bluetooth service or driver problem.
Select:
Start → Power → Restart
After Windows starts again, test Bluetooth before changing anything else.
Microsoft includes restarting the computer among its recommended Bluetooth troubleshooting steps.
If Bluetooth started failing after waking the computer from sleep, restarting is particularly worth trying.
6. Install Pending Windows 11 Updates
If Bluetooth stopped working after a Windows update—or suddenly stopped working without an obvious cause—check Windows Update.
Go to:
Settings → Windows Update → Check for updates
Install available updates and restart your computer.
Microsoft recommends checking for Windows updates when troubleshooting Bluetooth connection problems.
Updates can also contain driver or compatibility fixes.
Did Bluetooth stop immediately after an update?
If the problem began immediately after a particular update, don’t assume the Bluetooth hardware has failed.
First install any newer pending updates. If the problem persists, investigate the Bluetooth driver and, where available, consider rolling back the driver.
7. Update the Bluetooth Driver
A missing, outdated, incompatible, or corrupted Bluetooth driver can prevent Windows from detecting or communicating with Bluetooth hardware.
To update it:
- Right-click Start.
- Open Device Manager.
- Expand Bluetooth.
- Right-click your Bluetooth adapter.
- Select Update driver.
- Choose Search automatically for drivers.
- Restart the PC if prompted.
Microsoft recommends updating the Bluetooth adapter driver through Device Manager and restarting afterward.
The adapter name may contain terms such as Bluetooth, Radio, or a manufacturer name.
If Windows says the best driver is already installed
That doesn’t necessarily mean your PC has the newest driver.
Microsoft recommends checking the computer manufacturer’s support website for a newer driver designed specifically for your PC model.
8. Reinstall or Roll Back the Bluetooth Driver
If updating the driver doesn’t help, the installation itself may be corrupted.
Reinstall the driver
Open:
Device Manager → Bluetooth
Right-click your Bluetooth adapter and choose:
Uninstall device
Then restart Windows.
Microsoft says Windows can automatically reinstall the Bluetooth driver after the restart.
What if Bluetooth stopped after a driver or Windows update?
Try rolling back the driver if the option is available.
Open:
Device Manager → Bluetooth → Bluetooth adapter → Properties → Driver
If Roll Back Driver is available, follow the instructions.
Microsoft specifically recommends driver rollback when Bluetooth worked before a recent driver or Windows update.
Important
Use the Bluetooth driver supplied by your PC manufacturer whenever possible. Avoid downloading drivers from random third-party websites.
9. Restart the Bluetooth Support Service
Windows uses background services to manage Bluetooth functionality.
If the Bluetooth service is stuck or isn’t running correctly, restarting it may restore connectivity.
Press:
Windows + R
Type:
services.msc
and press Enter.
Find:
Bluetooth Support Service
Right-click it and choose Restart.
Microsoft lists restarting the Bluetooth Support Service as a troubleshooting step for Bluetooth connection problems, particularly when connections repeatedly drop.
After restarting the service, try connecting your Bluetooth device again.
10. Check Bluetooth Power Management
If Bluetooth connects but repeatedly disconnects—especially on a laptop—Windows power-management settings may be worth checking.
Open:
Device Manager → Bluetooth
Right-click your Bluetooth adapter and select Properties.
If you see a Power Management tab, look for:
Allow the computer to turn off this device to save power
If this option is enabled and you’re experiencing repeated Bluetooth disconnects, test with it disabled.
Microsoft includes this setting among its troubleshooting recommendations for Bluetooth connections that keep disconnecting.
This fix is especially relevant if Bluetooth works normally for a while and then drops unexpectedly.
11. Check Whether Windows Can Detect the Bluetooth Adapter
If the Bluetooth toggle is completely missing, don’t immediately assume the Bluetooth hardware has failed.
Open:
Device Manager
Look for:
- Bluetooth
- A Bluetooth adapter
- A wireless adapter
- Unknown devices
- Devices with a warning icon
Microsoft notes that a missing Bluetooth option can result from driver problems, stopped services, hardware issues, or Windows update problems.
If the adapter appears but is disabled, right-click it and choose Enable device if that option is available.
Bluetooth isn’t listed at all
If Bluetooth is absent from Settings and Device Manager, check whether your PC actually supports Bluetooth.
Some desktop computers don’t include built-in Bluetooth. In that situation, a compatible USB Bluetooth adapter may be required.
Dell also recommends checking the PC’s hardware configuration and BIOS/firmware when Bluetooth isn’t detected, particularly when the Bluetooth adapter isn’t appearing in Windows.
If both Bluetooth and Wi-Fi disappear simultaneously, pay particular attention to the wireless adapter, its driver, firmware, and hardware detection.
What If Bluetooth Is Missing From Windows 11?
If you don’t see the Bluetooth toggle under Settings → Bluetooth & devices, work through these checks in this order:
- Restart the PC.
- Run the Bluetooth troubleshooter in Get Help.
- Check Device Manager.
- Enable the Bluetooth adapter if it is disabled.
- Show hidden devices in Device Manager if appropriate.
- Install the correct manufacturer Bluetooth driver.
- Check Windows Update.
- Check whether Bluetooth is supported by the PC.
- Check firmware/BIOS settings if the manufacturer provides a Bluetooth option.
Microsoft specifically identifies driver compatibility, stopped services, hardware malfunction, and Windows updates as possible reasons Bluetooth can disappear from Windows.
What If Bluetooth Connects but Keeps Disconnecting?
Repeated disconnections usually require a slightly different approach.
Try these steps:
- Charge the Bluetooth accessory.
- Move it closer to the PC.
- Remove and re-pair it.
- Restart the Bluetooth Support Service.
- Update the Bluetooth driver.
- Check Bluetooth power-management settings.
- Install pending Windows updates.
- Test another Bluetooth device.
Microsoft specifically recommends checking power-saving settings, restarting the Bluetooth Support Service, and updating drivers for persistent Bluetooth disconnections.
Also consider interference. Microsoft notes that some USB 3.0 devices can interfere with Bluetooth connections, so moving a Bluetooth accessory away from nearby USB devices can sometimes help.
What If Bluetooth Is Connected but There Is No Sound?
If your Bluetooth headphones or speaker says Connected but you hear nothing, Bluetooth itself may be working.
The problem may instead be Windows audio routing.
Check:
Settings → System → Sound
Then select your Bluetooth headphones or speaker as the output device.
Also check the device’s volume and make sure it isn’t muted.
If another Bluetooth device works normally, focus on the audio device and Windows sound settings rather than immediately reinstalling the Bluetooth driver.
Should You Reset Windows 11?
Usually, no.
A Windows reset should be a last resort, not one of the first Bluetooth troubleshooting steps.
Before considering a reset, work through:
- Bluetooth settings
- Device pairing
- Get Help troubleshooter
- Windows Update
- Bluetooth driver update
- Driver reinstall
- Driver rollback
- Bluetooth Support Service
- Power-management settings
- Hardware detection
Dell likewise recommends trying less destructive troubleshooting options before considering a Windows reset.
When Is Bluetooth Hardware Probably the Problem?
Hardware becomes more suspicious when:
- Bluetooth isn’t detected anywhere in Windows.
- The correct driver cannot detect the adapter.
- Bluetooth and Wi-Fi fail simultaneously.
- The problem survives driver reinstallation and Windows updates.
- The Bluetooth adapter has disappeared from Device Manager.
- Another operating system or known-good installation also cannot detect the adapter.
However, don’t replace the wireless card immediately.
First verify that the PC actually supports Bluetooth and that the correct manufacturer driver is installed.
If the adapter remains undetected after software troubleshooting, professional hardware diagnostics may be appropriate.
5-Minute Bluetooth Troubleshooting Checklist
Before making advanced changes, run through this checklist:
- Bluetooth is turned on.
- Airplane mode is off.
- The Bluetooth accessory has power.
- The accessory is in pairing mode.
- The accessory is within range.
- Another Bluetooth device has been tested.
- Windows has been restarted.
- The Bluetooth troubleshooter has been run.
- Windows Update has been checked.
- The Bluetooth driver has been updated.
- The Bluetooth Support Service has been restarted.
If these don’t solve the problem, move on to driver reinstallation, rollback, and hardware detection.
Frequently Asked Questions
Why is Bluetooth not working in Windows 11?
Common causes include disabled Bluetooth, pairing problems, outdated or corrupted drivers, Windows updates, Bluetooth services, power-management settings, or an adapter that Windows cannot detect. Microsoft recommends starting with the Windows Bluetooth troubleshooter and then checking settings, devices, drivers, and updates.
Why did Bluetooth disappear from Windows 11?
Bluetooth can disappear when Windows cannot detect or enable the Bluetooth feature. Microsoft identifies driver problems, stopped services, hardware issues, incorrect settings, and Windows updates as possible causes.
How do I fix Bluetooth that won’t connect to headphones?
Make sure the headphones are charged and in pairing mode, toggle Bluetooth off and on, remove the headphones from Windows, and pair them again. If that doesn’t work, update the Bluetooth driver and run the Windows Bluetooth troubleshooter.
How do I reinstall Bluetooth drivers in Windows 11?
Open Device Manager, expand Bluetooth, right-click the Bluetooth adapter, select Uninstall device, and restart the PC. Microsoft says Windows should reinstall the Bluetooth driver after restarting.
Why does Bluetooth keep disconnecting?
Possible causes include power-management settings, outdated drivers, service problems, interference, or device-specific connection problems. Restarting the Bluetooth Support Service, updating drivers, and checking the adapter’s power-management settings are useful next steps.
What if Bluetooth and Wi-Fi stopped working at the same time?
Because Bluetooth and Wi-Fi can share the same wireless hardware, simultaneous failure points toward a driver, firmware, adapter, or hardware-detection problem. Check Device Manager and install the manufacturer’s current wireless/Bluetooth drivers before assuming the hardware has failed.
Final Takeaway
If Bluetooth is not working in Windows 11, don’t jump straight to reinstalling Windows or replacing the Bluetooth adapter.
Start with the simple checks: turn Bluetooth back on, verify the accessory is powered and in pairing mode, restart Windows, and run the Bluetooth troubleshooter.
If that doesn’t work, move systematically through Windows Update, Bluetooth drivers, driver reinstallation or rollback, the Bluetooth Support Service, power-management settings, and finally hardware detection.
The most important clue is what exactly has stopped working. A missing Bluetooth toggle, one device refusing to pair, repeated disconnections, and complete adapter disappearance can have very different causes.
When you diagnose that symptom first, you can usually find the right fix without changing settings you don’t need to touch.
Safety note: Use the exact instructions for your Windows version and PC model. When installing drivers, prefer Windows Update or the computer/adapter manufacturer’s official support site.
