If Bluetooth is not working on Windows 11, the right fix depends on what is actually happening. A missing Bluetooth toggle points toward a different problem than headphones that appear in the device list but refuse to connect.
Bluetooth problems can come from pairing mode, low accessory battery, discovery settings, Airplane mode, drivers, Windows updates, power-saving settings, interference, or the Bluetooth adapter itself.
Quick answer: Restart the PC and Bluetooth accessory, confirm Bluetooth is enabled, turn off Airplane mode, put the accessory into pairing mode, and try removing and pairing it again. If the device does not appear at all, switch Bluetooth device discovery to Advanced. If Bluetooth itself is missing from Windows, run the Get Help Bluetooth troubleshooter and check the Bluetooth adapter and driver in Device Manager.
First: What Bluetooth Problem Do You Have?
Before reinstalling drivers or changing Windows services, identify the symptom.
| Bluetooth Problem | Best Place to Start |
|---|---|
| Bluetooth toggle is completely missing | Troubleshooter, Device Manager and drivers |
| Bluetooth is on but device does not appear | Pairing mode and Advanced discovery |
| Device appears but will not connect | Remove and pair again |
| Bluetooth keeps disconnecting | Battery, power saving, driver and Bluetooth service |
| Headphones connect but have no sound | Windows audio output settings |
| Only one Bluetooth device fails | Accessory or pairing issue |
| No Bluetooth devices work | Windows adapter, driver or hardware |
This distinction can save a lot of unnecessary troubleshooting.
Restart the PC and Bluetooth Device
Start with a normal restart before making deeper Windows changes.
- Save your work.
- Select Start > Power > Restart.
- Turn the Bluetooth accessory off.
- Wait a few seconds.
- Turn the accessory back on.
- Try connecting again.
Microsoft includes restarting both the Windows PC and Bluetooth accessory among its current troubleshooting steps.
You can also review Microsoft's official Bluetooth troubleshooting guide.
Make Sure Bluetooth Is Turned On
On Windows 11, open:
Settings > Bluetooth & devices
Make sure Bluetooth is turned on.
You can also press Windows + A to open Quick Settings and check the Bluetooth control.
Check Airplane mode
While Quick Settings is open, make sure Airplane mode is turned off.
Microsoft specifically lists Airplane mode as something to check when Bluetooth disappears or stops working.
Check for a hardware wireless switch
Some laptops, especially older business laptops, have a physical wireless switch or manufacturer-specific keyboard shortcut.
If your laptop has one, verify that its wireless radios are enabled. Do not assume every Fn key controls Bluetooth—the function varies by laptop model.
Put the Device Into Pairing Mode
A Bluetooth accessory will not necessarily appear just because it is powered on.
It may need to be placed into pairing or discovery mode.
The method varies by device. It may involve:
- Holding the power button
- Holding a dedicated Bluetooth button
- Holding two buttons together
- Opening the charging case
- Using the device's settings menu
Check the accessory manufacturer's instructions if you are unsure.
Also make sure the accessory:
- Has enough battery charge
- Is reasonably close to the PC
- Is not already shutting down because of low battery
Microsoft specifically recommends checking battery level, pairing mode and distance when a Bluetooth device will not connect.
See Microsoft's Bluetooth connection troubleshooting guide.
Use Advanced Bluetooth Device Discovery
This is an important Windows 11 setting if a device refuses to appear during pairing.
Open:
Settings > Bluetooth & devices > Devices
Under Device settings, look for:
Bluetooth devices discovery
Change it from Default to Advanced.
Microsoft currently explains the options as:
- Default: shows common Bluetooth device types
- Advanced: shows all types of Bluetooth devices that Windows can discover
After changing the setting, put the accessory back into pairing mode and select:
Add device
If the device now appears, continue the normal pairing process.
Microsoft documents this setting in its current Windows Bluetooth guide.
Remove and Pair the Device Again
If the accessory appears in Windows but refuses to connect, its saved pairing information may need to be recreated.
Open:
Settings > Bluetooth & devices > Devices
- Find the affected Bluetooth device.
- Select the three-dot menu beside it.
- Select Remove device.
- Confirm the removal.
- Turn the accessory off and back on.
- Put it into pairing mode.
- Select Add device.
- Pair it again.
Microsoft recommends removing and re-adding devices that appear in Windows but will not connect.
Check Whether It Is Connected Somewhere Else
Some Bluetooth accessories automatically reconnect to a phone, tablet, TV or another computer they were previously paired with.
If the accessory does not enter pairing mode or Windows cannot connect to it:
- Check nearby devices that have used the accessory before.
- Temporarily disconnect the accessory from those devices.
- Put the accessory back into pairing mode.
- Try Windows again.
This is particularly common with headphones, speakers, keyboards and mice that automatically reconnect to the last device they used.
Run the Windows Bluetooth Troubleshooter
Microsoft currently recommends the automated Bluetooth troubleshooter in the Get Help app for Windows 11.
Open Start and search for:
Get Help
Then search inside the app for:
Bluetooth troubleshooter
Follow the diagnostic steps provided.
This should now be preferred over old tutorials that rely only on the older Control Panel or legacy troubleshooting screens.
Microsoft's current troubleshooter guidance is included in its Bluetooth support page.
Fix a Missing Bluetooth Toggle or Icon
If Bluetooth has completely disappeared from Settings > Bluetooth & devices, the problem is different from a failed accessory pairing.
Microsoft says a missing or grayed-out Bluetooth control can be caused by:
- Driver problems
- Windows updates
- Incorrect settings
- Stopped services
- Bluetooth hardware problems
Start with:
- Restart the PC.
- Confirm Airplane mode is off.
- Run the Bluetooth troubleshooter.
- Install Windows updates.
- Check Device Manager.
Check Device Manager
Right-click Start and select Device Manager.
Look for:
Bluetooth
Your adapter may have a manufacturer-specific name rather than simply saying “Bluetooth Adapter.”
If Bluetooth is missing from Device Manager too, check Other devices for an unidentified device.
Microsoft notes that if Windows cannot detect the Bluetooth adapter or its driver is not installed, Bluetooth settings may also disappear.
See Microsoft's Bluetooth disappeared troubleshooting guide.
Update the Bluetooth Driver
An outdated or incompatible Bluetooth driver can cause pairing, connection and detection problems.
Open:
Device Manager > Bluetooth
- Right-click the Bluetooth adapter.
- Select Update driver.
- Select Search automatically for drivers.
- Install an update if Windows finds one.
- Restart the PC afterward.
If Windows says the best driver is already installed, that does not always mean the laptop manufacturer has no newer driver.
Microsoft recommends checking the PC manufacturer's official support site when Windows cannot locate a newer Bluetooth driver.
Use your exact laptop, motherboard or PC model rather than downloading drivers from random driver-download websites.
Microsoft provides current instructions in its Bluetooth driver update guide.
Reinstall the Bluetooth Driver
If updating the driver does not help, Microsoft also recommends reinstalling it.
Open:
Device Manager > Bluetooth
- Right-click the Bluetooth adapter.
- Select Uninstall device.
- Confirm the uninstall.
- Restart the computer.
Microsoft says Windows normally reinstalls the Bluetooth driver automatically after restart.
If Bluetooth does not return, download the appropriate Bluetooth driver from your PC manufacturer's official support page.
Do not install a Bluetooth driver intended for a different computer model simply because the Bluetooth chipset name appears similar.
Roll Back the Driver After an Update
If Bluetooth worked normally until a recent Windows or driver update, updating again may not be the best first move.
Microsoft specifically recommends trying a driver rollback when the problem began after an update.
Open:
Device Manager > Bluetooth
- Right-click your Bluetooth adapter.
- Select Properties.
- Open the Driver tab.
- Select Roll Back Driver if the button is available.
- Follow the instructions.
- Restart Windows.
If Roll Back Driver is unavailable, Windows may not have a previous driver package stored.
Install Windows Updates
Bluetooth drivers and compatibility fixes can also arrive through Windows Update.
Open:
Settings > Windows Update
Select:
Check for updates
Install appropriate available updates and restart the PC.
Microsoft specifically includes Windows Update in its current troubleshooting for missing Bluetooth and driver problems.
Fix Bluetooth That Keeps Disconnecting
If a device pairs successfully but repeatedly drops the connection, check a different set of causes.
Start with:
- Charge the Bluetooth accessory.
- Move it closer to the PC.
- Restart both devices.
- Remove and pair it again.
- Update the Bluetooth driver.
- Check Windows Update.
Temporarily test without Energy Saver
Microsoft recommends checking Energy Saver when troubleshooting repeated Bluetooth disconnects.
If Energy Saver is enabled, temporarily turn it off and test the connection again.
Check Bluetooth adapter power management
Some Bluetooth adapters expose a Power Management tab in Device Manager.
If your adapter has it:
- Open Device Manager.
- Expand Bluetooth.
- Open the Bluetooth adapter's Properties.
- Select Power Management.
- Temporarily clear Allow the computer to turn off this device to save power.
- Test Bluetooth again.
The Power Management tab is not available on every Bluetooth adapter, so do not worry if you do not see it.
Microsoft includes this setting in its Bluetooth disconnecting guide.
Restart the Bluetooth Support Service
If Bluetooth repeatedly disconnects or Windows behaves as though the Bluetooth subsystem has stopped responding, Microsoft also recommends restarting the Bluetooth Support Service.
- Press Windows + R.
- Type
services.msc. - Press Enter.
- Find Bluetooth Support Service.
- Right-click it.
- Select Restart.
Then test Bluetooth again.
Do not randomly change the service's startup type simply because an older tutorial tells you to. Microsoft's current disconnecting guidance recommends restarting the service; it does not require users to force its startup type to Automatic.
Check for USB 3.0 Interference
This is an unusual but officially documented cause of Bluetooth problems.
Microsoft warns that some poorly shielded USB devices connected to a USB 3.0 port can interfere with nearby Bluetooth connections.
If Bluetooth becomes unstable only when a particular USB device is connected:
- Disconnect that USB device temporarily.
- Test Bluetooth again.
- If possible, move the USB device farther away from the Bluetooth adapter or accessory.
- Try another USB port.
This is especially useful when Bluetooth becomes sluggish, loses range or disconnects only after connecting a particular USB drive, dock or peripheral.
Bluetooth Connected but No Sound
If your headphones or speaker say Connected but Windows still plays audio through the laptop speakers, the Bluetooth connection itself may be working correctly.
That becomes an audio-output problem rather than a general Bluetooth pairing problem.
First check:
Settings > System > Sound
Make sure the correct Bluetooth headphones or speaker is selected under Output.
For the full audio-specific troubleshooting process, see our Bluetooth headphones connected but no sound on Windows guide.
Microsoft also has a separate Bluetooth connected but no sound guide.
Check for a Bluetooth Hardware Problem
If nothing has fixed the problem, determine whether Windows or the Bluetooth accessory is actually at fault.
Test the Bluetooth accessory with another device
Try connecting the headphones, mouse, keyboard or speaker to another phone, tablet or computer.
If the accessory also fails there, the accessory itself may be the problem.
Test another Bluetooth accessory with the PC
If possible, try a different known-working Bluetooth device with Windows.
If multiple accessories fail on the same PC, focus on the Windows Bluetooth adapter, drivers or hardware.
Check the PC specifications
If Bluetooth has never appeared on a desktop PC, confirm that the computer actually includes a Bluetooth adapter.
Not every desktop motherboard has built-in Bluetooth.
Microsoft specifically recommends confirming Bluetooth hardware capability when Bluetooth is completely missing.
Possible adapter failure
A hardware problem becomes more likely if:
- The Bluetooth adapter repeatedly disappears from Device Manager.
- The manufacturer's hardware diagnostics report a wireless problem.
- Bluetooth vanished after physical or liquid damage.
- The correct drivers will not detect the adapter.
- Wi-Fi and Bluetooth from the same wireless module are both failing.
In that situation, check the PC manufacturer's diagnostics and support options.
Windows 10 Bluetooth Note
This page originally covered both Windows 10 and Windows 11, which is why the existing URL still contains windows-10-11.
However, Microsoft ended standard support for Windows 10 on October 14, 2025.
Windows 10 PCs still function, and Microsoft continues to publish some legacy Bluetooth instructions, but Windows 11 should now be the primary platform for current troubleshooting.
Microsoft recommends upgrading eligible computers to Windows 11 or using an appropriate Extended Security Updates option where applicable.

Yes. Microsoft currently recommends running its automated Bluetooth troubleshooter through the Get Help app.
Why does Bluetooth work with one device but not another?
If other Bluetooth devices connect normally, Windows and the Bluetooth adapter are probably functioning. Focus on the affected accessory's battery, pairing mode, saved pairing and compatibility.
Can my PC simply not have Bluetooth?
Yes. Some desktop computers and older laptops do not include a Bluetooth adapter. Check the manufacturer's specifications or Device Manager before assuming the driver is broken.
Is Windows 10 still supported?
Standard Windows 10 support ended on October 14, 2025. Microsoft recommends moving eligible PCs to Windows 11 or using an applicable Extended Security Updates option.
Final Thoughts
If Bluetooth is not working on Windows 11, start by identifying whether Bluetooth itself is missing, the accessory cannot be discovered, pairing fails, or an existing connection keeps dropping.
For devices that are not appearing, confirm pairing mode and try Windows 11's Advanced Bluetooth discovery setting. For devices that refuse to reconnect, remove and pair them again.
If Bluetooth is missing completely, run the Get Help troubleshooter, check Device Manager, install Windows updates and update the Bluetooth driver. Reinstall or roll back the driver only when the simpler steps do not solve the problem.
If multiple known-working Bluetooth devices fail and the adapter repeatedly disappears from Device Manager, the problem may be with the Bluetooth hardware rather than Windows settings.
