Bluetooth makes it easy to connect wireless headphones, keyboards, mice, speakers, and other accessories to a Windows PC. But when Bluetooth stops working, even a simple task like joining an online meeting or listening to music can become frustrating.
Sometimes the Bluetooth toggle disappears from Settings. In other cases, Windows shows Bluetooth as enabled but cannot find nearby devices. You might also see a device listed as connected even though it does not work properly.
The good news is that you do not necessarily need a new Bluetooth adapter or a Windows reinstall. Many Bluetooth problems are caused by incorrect settings, pairing issues, outdated drivers, or temporary software glitches.
This guide explains how to fix Bluetooth not working on Windows 11, starting with the simplest checks and moving toward more advanced solutions. Follow the steps in order, and stop when your Bluetooth connection works again.

1. Check Whether Your PC Supports Bluetooth
Before changing Windows settings, confirm that your computer actually has Bluetooth hardware.
Most modern laptops include Bluetooth, but some desktop computers do not. A desktop may have Wi-Fi without Bluetooth, depending on its motherboard or wireless adapter. Bluetooth may also stop appearing if its driver is missing or the hardware is not being detected.
Here is how to check:
- Right-click the Start button.
- Select Device Manager.
- Look for a category named Bluetooth.
- Expand it if it appears.
If you see a Bluetooth adapter listed, such as an Intel Wireless Bluetooth device, your computer is detecting Bluetooth hardware.
If the category is missing, check the following:
- Select View > Show hidden devices in Device Manager.
- Look under Network adapters and Other devices for an unidentified wireless device.
- Check your laptop or motherboard specifications to confirm Bluetooth support.
- If you use a desktop, verify whether its Wi-Fi adapter also supports Bluetooth.
Some internal wireless cards use separate connections for Wi-Fi and Bluetooth. On certain desktops, Bluetooth may require an additional USB cable connected from the wireless card to a motherboard USB header.
Important: If your computer does not have Bluetooth hardware, installing a driver alone will not add Bluetooth functionality. A compatible USB Bluetooth adapter may be the simplest solution.
2. Turn Bluetooth On and Disable Airplane Mode
A disabled Bluetooth setting is one of the easiest problems to overlook.
On Windows 11, follow these steps:
- Press Windows + A to open Quick Settings.
- Find the Bluetooth button.
- If Bluetooth is off, select it to turn it on.
- Make sure Airplane mode is disabled.
You can also open Settings > Bluetooth & devices and check the Bluetooth switch.
If the Bluetooth button is missing from Quick Settings, open Settings and look for the Bluetooth option there.
The next step depends on what you see:
- Bluetooth is available but switched off: Turn it on and test your device.
- Bluetooth is switched on but cannot find devices: Continue to the pairing steps below.
- Bluetooth is missing entirely: Skip ahead to the driver and hardware troubleshooting sections.
If Bluetooth cannot be enabled, repeatedly clicking the toggle is unlikely to solve the underlying issue. The driver, Windows service, or hardware may need attention.
3. Restart Your PC and Bluetooth Accessory
Restarting may sound too simple, but it can clear temporary problems affecting Bluetooth communication.
Start with the accessory you are trying to connect. Turn off your headphones, speaker, mouse, or keyboard. Wait several seconds, then turn it back on.
Next, restart your computer:
- Save any open work.
- Select Start > Power > Restart.
- Wait for Windows to load completely.
- Try connecting your Bluetooth device again.
If you are using wireless headphones, make sure they have sufficient battery power. Some accessories behave unpredictably when their battery is nearly empty.
Also check whether the device is already connected to your phone, tablet, or another computer. Many headphones automatically reconnect to a previously paired device, which can prevent them from connecting to your PC.
Disconnect the accessory from the other device temporarily and try pairing again.
4. Put Your Device Into Pairing Mode
One common reason Windows cannot find Bluetooth devices is that the accessory is not discoverable.
Turning on a Bluetooth accessory does not always put it into pairing mode. Depending on the manufacturer, you may need to hold a dedicated Bluetooth button or press and hold the power button for a few seconds.
Check the device’s manual for the correct pairing procedure.
Once the accessory is in pairing mode:
- Open Settings > Bluetooth & devices.
- Select Add device.
- Choose Bluetooth.
- Wait for Windows to scan for nearby devices.
- Select your accessory when it appears.
- Follow any pairing instructions on the screen.
Keep the accessory close to your computer during setup.
If your device does not appear, switch it off and on, activate pairing mode again, and repeat the scan.
On some Windows 11 versions, you can also change which devices appear in discovery results. Open Settings > Bluetooth & devices > Devices and look for the Bluetooth device discovery setting. If available, change it from Default to Advanced.
The exact wording and location can vary by Windows version.
5. Remove and Reconnect the Bluetooth Device
If Windows recognizes your accessory but refuses to connect, its saved pairing information may be causing the problem.
Removing the device and pairing it again can help.
Follow these steps:
- Open Settings > Bluetooth & devices.
- Find the accessory that is not working.
- Select the three-dot menu beside it, if available.
- Choose Remove device.
- Confirm the removal.
- Put the accessory into pairing mode.
- Select Add device > Bluetooth.
- Choose the accessory and complete pairing.
After reconnecting, test the device rather than assuming that successful pairing means everything is fixed.
For example, play audio through your headphones, move your mouse, or type using your wireless keyboard.
If the device is still unavailable, test it with another compatible computer or phone. This helps determine whether the problem is with Windows or the accessory itself.
Keep in mind that removing a device deletes its saved pairing on your PC. You may need to pair it again manually.
6. Run the Windows Bluetooth Troubleshooter
Windows 11 includes troubleshooting tools that can identify and address certain Bluetooth problems.
Microsoft provides an automated Bluetooth troubleshooter through the Get Help app.
To try it:
- Open the Start menu.
- Search for Get Help.
- Open the app.
- Search for Bluetooth troubleshooting or Bluetooth problems.
- Follow the diagnostic prompts.
The available diagnostic flow may change with Windows updates.
The troubleshooter can help identify configuration or service issues, but it cannot repair defective hardware. If it does not resolve the problem, continue with the next methods.
You can also open Settings > System > Troubleshoot > Other troubleshooters to check the available troubleshooting options. The Bluetooth troubleshooter may not appear as a separate option on every Windows 11 build.
7. Update the Bluetooth Driver
A Bluetooth driver allows Windows to communicate with the computer’s Bluetooth hardware. If the driver is outdated, corrupted, or incompatible with a recent Windows update, connections may fail.
Updating the driver is particularly worth trying if Bluetooth stopped working after a system update or if the Bluetooth option disappears intermittently.
Update the driver through Device Manager
- Right-click Start and open Device Manager.
- Expand Bluetooth.
- Right-click your Bluetooth adapter.
- Select Update driver.
- Choose Search automatically for drivers.
- Follow the instructions provided by Windows.
If Windows reports that the best driver is already installed, do not assume that the manufacturer’s latest driver is necessarily installed. Windows may not find every available version through this search.
Download the driver from your computer manufacturer
If the problem continues, visit the official support website for your laptop or motherboard manufacturer.
Search using your exact computer model, then locate the Bluetooth driver for your installed Windows version.
For example, Intel-based systems may use Intel wireless Bluetooth drivers, while other computers may use adapters from different manufacturers.
Download drivers only from trusted, official sources. Avoid third-party driver-updater utilities that promise to fix every driver automatically.
Before installing a new driver, confirm that it matches your hardware and Windows version. Restart your PC after installation if required.
8. Restart the Bluetooth Support Service
Windows uses background services to support Bluetooth functionality. If the relevant service is stopped or experiencing an issue, pairing and device discovery may not work correctly.
You can check the Bluetooth Support Service manually.
- Press Windows + R.
- Type
services.msc. - Press Enter.
- Find Bluetooth Support Service.
- Right-click it.
- Select Restart if the option is available.
If the service is stopped, you may see a Start option instead.
You can open Properties to inspect its startup configuration, but avoid changing service settings unnecessarily. Windows configurations and device manufacturers can differ, and changing unrelated services may create additional problems.
After restarting the service, open Bluetooth settings and test your accessory again.
If the service repeatedly stops or cannot start, note any error message. That information may help identify a deeper driver or Windows configuration problem.
9. Check Bluetooth Power Management
Some Bluetooth adapters have power-saving settings that can affect connectivity, particularly on laptops.
If Bluetooth disconnects frequently, disappears after sleep, or stops working when your computer wakes up, checking power management may help.
Here is how:
- Right-click Start and open Device Manager.
- Expand Bluetooth.
- Right-click your Bluetooth adapter.
- Select Properties.
- Look for a Power Management tab.
If the tab is available and contains the option Allow the computer to turn off this device to save power, you can try clearing that checkbox.
Select OK, restart your computer, and test Bluetooth.
Not every adapter exposes this setting. If you cannot find it, do not worry; simply move to the next method.
You can also temporarily disable Windows Energy Saver or Battery Saver to see whether the connection becomes more stable. If that makes no difference, restore your preferred power settings.
10. Reinstall the Bluetooth Adapter
If Bluetooth appears in Device Manager but continues to malfunction, reinstalling the adapter’s driver may help.
This is a more advanced step, so try the simpler solutions first.
Before you begin
Download the correct Bluetooth driver from your computer manufacturer’s official website if possible. Save it somewhere easy to find.
If your computer depends on Bluetooth for an essential input device, make sure you have another way to control it, such as a wired mouse or keyboard.
Reinstall the adapter
- Open Device Manager.
- Expand Bluetooth.
- Right-click the relevant Bluetooth adapter.
- Select Uninstall device.
- Review the confirmation carefully and proceed.
- Restart your computer.
Avoid selecting an option to remove the driver package unless you understand the consequences and have a suitable replacement available.
After restarting, Windows may detect the hardware and reinstall a driver automatically. If Bluetooth does not return, open Device Manager and select Action > Scan for hardware changes, if available.
You can then install the driver downloaded from the manufacturer’s website.
If the adapter remains missing, check Device Manager for hardware errors or unknown devices. Persistent detection problems may require manufacturer support or a hardware inspection.
11. Install Pending Windows Updates
Windows updates can include driver compatibility improvements, bug fixes, and changes that affect wireless devices.
If your Bluetooth problem started after an update, check whether additional updates are available.
- Open Settings.
- Select Windows Update.
- Choose Check for updates.
- Install applicable updates.
- Restart your computer if requested.
- Test Bluetooth again.
You can also review optional driver updates if Windows offers them, but install only drivers that match your hardware.
If Bluetooth stopped working immediately after a particular update, avoid uninstalling updates at random. First, check your manufacturer’s support information and Microsoft’s documentation for known issues affecting your Windows version.
Removing a security update can expose your computer to vulnerabilities. Treat it as a targeted troubleshooting step rather than a routine fix.
12. Reset Network Settings as a Last Resort
A Windows network reset can help with certain networking configuration problems, but it is not a guaranteed fix for Bluetooth issues.
Consider it only after trying the previous steps and confirming that the problem may involve broader wireless or network configuration.
Before proceeding, be aware that a network reset can remove and reinstall network adapters and restore networking components to their defaults. You may need to reconnect to Wi-Fi, re-enter saved network passwords, or reinstall networking software.
To access the option:
- Open Settings.
- Select Network & internet.
- Open Advanced network settings.
- Look for Network reset, if available.
- Read the warning carefully.
- Proceed only if you understand the changes.
Restart your PC when prompted, then test Bluetooth.
Because a network reset affects more than Bluetooth alone, it should not be the first thing you try. If Wi-Fi works normally and only Bluetooth is affected, focus on the Bluetooth adapter, driver, service, and accessory instead.
13. What to Do When Bluetooth Still Does Not Work
If none of these methods fixes the issue, the next step is to narrow down the source of the problem.
Use the following table to identify a sensible next action.
| Problem | Likely area to investigate | Next step |
|---|---|---|
| Bluetooth toggle is missing | Driver, hardware detection, or unsupported hardware | Check Device Manager and PC specifications |
| Bluetooth is on, but no devices appear | Pairing mode, discovery, or accessory compatibility | Test another accessory and enable pairing mode |
| Device pairs but will not connect | Saved pairing information or accessory behavior | Remove and pair it again |
| Bluetooth disconnects after sleep | Power management or driver compatibility | Check power settings and update the driver |
| Bluetooth stopped after an update | Driver or Windows compatibility | Check manufacturer drivers and Windows updates |
| No Bluetooth devices work | PC adapter, driver, or Windows configuration | Check Device Manager and test the adapter |
| One accessory fails everywhere | Accessory battery, firmware, or hardware | Test it with another compatible device |
Test another Bluetooth accessory
Connect a different Bluetooth device to your PC.
If the second device works, your original accessory may be responsible for the problem.
If neither device works, focus on Windows settings, drivers, or the Bluetooth adapter.
Test the original accessory elsewhere
Try connecting your headphones, mouse, or speaker to another compatible device.
If it also fails there, check its battery, pairing procedure, manufacturer instructions, and hardware condition.
This simple comparison prevents unnecessary Windows changes when the real issue is the accessory.
Check for hardware problems
If Bluetooth is absent from Device Manager even after checking hidden devices and reinstalling the correct driver, the adapter may not be detected.
On a laptop, consult the manufacturer’s diagnostics or support service. On a desktop, check the wireless adapter’s specifications and installation.
Do not open a laptop or handle internal components unless you know how to do so safely. If the hardware is under warranty, contact the manufacturer before attempting a repair.
Frequently Asked Questions
Why is Bluetooth not showing in Windows 11?
Bluetooth may be missing because the PC does not have Bluetooth hardware, the driver is missing or corrupted, or Windows is not detecting the adapter. Check Device Manager, enable hidden devices, and confirm your computer’s specifications before installing drivers.
How do I fix Bluetooth when the toggle is greyed out?
Restart your computer, check Airplane mode, and inspect Device Manager for Bluetooth adapter errors. If the adapter has a warning icon, update or reinstall its compatible driver. A greyed-out toggle may indicate a driver, service, or hardware-detection issue.
Why does Windows 11 find my headphones but fail to connect?
Your headphones may not be in the correct pairing mode, may already be connected to another device, or may have stale pairing information. Charge them, disconnect them from other devices, remove the saved pairing in Windows, and pair them again.
Why does Bluetooth keep disconnecting from my laptop?
Possible causes include power-saving settings, an incompatible driver, interference, low accessory battery, or a problem with the accessory itself. Test the device near your laptop, check power management settings, and install the appropriate manufacturer driver.
Can I install Bluetooth on a computer that does not support it?
Yes. If your computer lacks built-in Bluetooth, you can generally add it using a compatible USB Bluetooth adapter. Check operating-system compatibility and manufacturer drivers before buying one.
Will resetting Windows fix Bluetooth?
A full Windows reset is rarely the best first step. Most Bluetooth problems should be investigated through settings, pairing, drivers, services, and hardware checks first. Resetting Windows can remove apps and settings, so consider it only after less disruptive solutions have failed and your important files are backed up.
Does updating a Bluetooth driver delete my files?
A normal Bluetooth driver update should not delete personal documents, photos, or other files. However, driver installation can affect device functionality, so use the correct driver from an official source and keep important files backed up.
Why did Bluetooth stop working after a Windows update?
The installed driver may no longer work correctly with the updated Windows version, or the update may have exposed an existing compatibility problem. Check for newer compatible drivers from your computer manufacturer and install any applicable follow-up Windows updates.
Conclusion
Bluetooth problems in Windows 11 can come from something as simple as a disabled setting or an accessory that is not in pairing mode. In other cases, the issue may involve a driver, Windows service, power-management setting, or hardware fault.
Start with the easiest checks: turn Bluetooth on, disable Airplane mode, restart your devices, and pair the accessory again. If that does not work, run the troubleshooter, update the driver, and inspect the Bluetooth adapter in Device Manager.
Avoid jumping straight to a network reset or Windows reinstall. A careful, step-by-step approach is more likely to identify the actual cause without changing settings you do not need to change.
If Bluetooth remains unavailable after these checks, use the adapter’s exact model and any Device Manager error information to guide your next step. That will make further troubleshooting much more specific and useful.
