Bluetooth Disappeared in Windows 11? Fix It

When the Bluetooth category is completely missing from Device Manager, select Action > Scan for hardware changes, install the correct Bluetooth and chipset drivers from your computer manufacturer, and perform a full shutdown. If Bluetooth vanished after an update, roll back the Bluetooth driver or remove the problematic update instead of immediately resetting Windows.

The right solution depends on what has disappeared. You may be dealing with:

• A missing Bluetooth tile in Quick Settings
• No Bluetooth on/off toggle in Settings
• A hidden or disabled Bluetooth adapter
• Bluetooth missing from Device Manager
• Bluetooth disappearing after a Windows update
• Bluetooth returning temporarily after a restart
• A laptop’s combined Wi-Fi and Bluetooth card not being detected

These symptoms look similar but do not always have the same cause.

Why Did Bluetooth Disappear in Windows 11?

Bluetooth can disappear when Windows cannot detect or enable the radio. Common causes include:

• Airplane mode is enabled.
• The Bluetooth adapter was disabled.
• A temporary power or sleep-state problem stopped the wireless card.
• The Bluetooth Support Service is not running.
• The driver is outdated, damaged, or incompatible.
• Windows Update replaced the manufacturer’s driver.
• The Bluetooth device is hidden in Device Manager.
• The combined Wi-Fi and Bluetooth card has a chipset or USB-controller problem.
• A BIOS or firmware setting disabled wireless communication.
• The PC does not have built-in Bluetooth.
• An internal card or USB Bluetooth adapter has failed.

Microsoft confirms that a missing or greyed-out Bluetooth toggle can be caused by settings, drivers, stopped services, recent Windows updates, or hardware faults. Its current Bluetooth disappeared support page recommends beginning with the automated troubleshooter and driver checks.

First Check What Is Actually Missing

Before changing drivers, look in three locations.

Check Quick Settings

1. Press Windows + A.
2. Look for the Bluetooth tile.

If Bluetooth is available in Settings but absent here, the hardware and driver may be working. Only the Quick Settings tile may have been removed.

Check Windows Settings

1. Press Windows + I.
2. Select Bluetooth & devices.
3. Look for the Bluetooth on/off switch.

If the switch appears, Windows detects a Bluetooth radio. If the switch is gone, continue to Device Manager.

Check Device Manager

1. Right-click the Start button.
2. Select Device Manager.
3. Look for a Bluetooth category.
4. Also check Network adapters, Other devices, and Universal Serial Bus controllers.

The Bluetooth radio may appear under its manufacturer’s name, such as Intel, Realtek, MediaTek, Qualcomm, Broadcom, or a generic Bluetooth adapter.

1. Restart Windows 11

A proper restart clears temporary driver, service, and power-state problems.

1. Save your work.
2. Select Start > Power > Restart.
3. Sign back in.
4. Press Windows + A.
5. Check Settings > Bluetooth & devices.

Choose Restart rather than shutting the lid or putting the computer to sleep. Sleep may preserve the same failed wireless-card state.

If Bluetooth returns but disappears again after sleep, focus later on driver updates and power-management settings.

2. Perform a Full Shutdown

Fast Startup can preserve part of the previous hardware state during a normal shutdown. A complete shutdown can force the wireless card to initialise again.

1. Save all open work.
2. Hold Shift.
3. While holding Shift, select Start > Power > Shut down.
4. Wait approximately 30 seconds.
5. Turn the computer back on.

For a desktop with a removable power cable, shut down normally before disconnecting power. Do not unplug a running computer.

If a laptop has a manufacturer-supported hardware-reset procedure, follow its official instructions. Avoid opening the laptop or disconnecting an internal battery unless you are qualified to do so.

3. Make Sure Airplane Mode Is Off

Airplane mode disables wireless radios and can make Bluetooth unavailable.

1. Press Windows + A.
2. Find Airplane mode.
3. Make sure it is turned off.
4. Wait several seconds.
5. Check whether Bluetooth returns.

You can also open Settings > Network & internet > Airplane mode.

Some laptops have a physical wireless switch or an Fn-key combination. Check the keyboard for an antenna or airplane symbol. Make sure wireless communication has not been disabled accidentally.

4. Run the Bluetooth Troubleshooter

Microsoft recommends starting with the automated Bluetooth troubleshooter in the Get Help app on Windows 11.

1. Open the Start menu.
2. Search for Get Help.
3. Open the app.
4. Search for Bluetooth troubleshooter.
5. Follow the diagnostic prompts.
6. Apply any recommended repair.
7. Restart the computer if requested.

You may also find troubleshooting options under:

Settings > System > Troubleshoot > Other troubleshooters

The exact location can vary by Windows 11 version. Microsoft’s Bluetooth troubleshooting page identifies Get Help as the current starting point.

The troubleshooter can detect disabled settings, driver problems, stopped components, and common configuration faults. If it reports that the PC has no Bluetooth adapter, confirm the result in Device Manager before assuming the hardware is absent.

5. Add Bluetooth Back to Quick Settings

Use this fix when Bluetooth works in Settings but its Quick Settings button has disappeared.

1. Press Windows + A.
2. Look for an option to edit Quick Settings.
3. Select Add if the current Windows build offers it.
4. Choose Bluetooth.
5. Save the layout.

The editing interface has changed across Windows 11 releases. Some versions automatically display Bluetooth when the radio is detected.

If Bluetooth is also missing from Settings and Device Manager, adding a tile will not solve the underlying problem. Continue with the adapter and driver checks.

6. Show Hidden Devices in Device Manager

Windows may retain the Bluetooth adapter as a hidden device after a driver or hardware-detection fault.

1. Open Device Manager.
2. Select View.
3. Choose Show hidden devices.
4. Expand Bluetooth.
5. Look for a faded Bluetooth adapter.

Also expand:

• Network adapters
• Other devices
• Universal Serial Bus controllers

If the adapter appears faded, right-click it and open Properties. Check the Device status message and error code.

Do not uninstall every faded Bluetooth entry. Some entries represent previously paired devices rather than the computer’s Bluetooth radio.

7. Enable the Bluetooth Adapter

The adapter may be present but disabled.

1. Open Device Manager.
2. Expand Bluetooth.
3. Right-click the main Bluetooth adapter.
4. Select Enable device if that option appears.
5. Restart Windows.

If the menu displays Disable device, the adapter is already enabled.

Check Network adapters too because some wireless cards are listed under their manufacturer’s name. Avoid disabling the active Wi-Fi adapter by mistake.

8. Scan for Hardware Changes

If the Bluetooth category is missing:

1. Open Device Manager.
2. Select your computer name at the top.
3. Open Action.
4. Select Scan for hardware changes.
5. Wait for Windows to refresh the device list.

If Bluetooth appears, restart the PC and check the Settings toggle.

Scanning does not install a missing manufacturer driver in every case. It only tells Windows to detect connected hardware again.

9. Restart the Bluetooth Support Service

Windows services manage Bluetooth discovery and communication.

1. Press Windows + R.
2. Enter services.msc.
3. Select OK.
4. Find Bluetooth Support Service.
5. Right-click it.
6. Choose Restart if available.
7. Open Properties.
8. Make sure the service is not set to Disabled.

Depending on the computer and Windows version, you may also see Bluetooth Audio Gateway Service or Bluetooth User Support Service.

Do not randomly change every Bluetooth-related service to Automatic. Windows can manage some services through trigger-based startup. The important check is that the required service is not disabled and can start without an error.

Restart Windows after making a necessary service correction.

10. Update the Bluetooth Driver

An outdated or incompatible driver is one of the most common reasons the Bluetooth toggle disappears after an update.

1. Open Device Manager.
2. Expand Bluetooth.
3. Right-click the main Bluetooth adapter.
4. Select Update driver.
5. Choose Search automatically for drivers.
6. Install an available update.
7. Restart the PC.

Microsoft’s Bluetooth driver instructions note that a newer driver may still be available from the PC manufacturer even when Device Manager says the best driver is already installed.

If the Bluetooth category is missing, identify the computer’s exact model and download the driver from its manufacturer instead.

11. Install Optional Driver Updates

Windows Update may offer Bluetooth, chipset, USB, or wireless drivers separately from normal security updates.

1. Open Settings.
2. Select Windows Update.
3. Open Advanced options.
4. Select Optional updates.
5. Expand Driver updates.
6. Look for a relevant Bluetooth or wireless driver.
7. Install it.
8. Restart Windows.

Install only drivers that match the computer’s hardware. Do not select unrelated optional drivers simply because they are available.

If the manufacturer provides a newer recommended package, prefer its model-specific instructions.

12. Download the Driver From the PC Manufacturer

This is one of the most important fixes when Bluetooth is completely absent from Device Manager.

1. Identify the laptop, motherboard, or desktop model.
2. Visit the manufacturer’s official support website.
3. Search for the exact model or serial number.
4. Select Windows 11.
5. Download the Bluetooth driver.
6. Also check for recommended wireless LAN and chipset packages.
7. Install them according to the manufacturer’s instructions.
8. Restart Windows.

Common support sources include Dell, HP, Lenovo, ASUS, Acer, MSI, Microsoft Surface, and the motherboard manufacturer.

Avoid generic driver-download websites. They may provide an incorrect, modified, or outdated package.

Many laptops use a combined Wi-Fi and Bluetooth card. The Wi-Fi and Bluetooth components may require separate driver packages even though they are located on the same hardware.

If both Wi-Fi and Bluetooth disappeared, read Windows could not find a driver for your network adapter for additional network-driver checks.

13. Reinstall the Bluetooth Driver

Reinstall the adapter when it appears in Device Manager but its driver is damaged.

Before uninstalling, download the correct replacement driver from the PC manufacturer. This is particularly important if the computer has no wired internet connection.

Then:

1. Open Device Manager.
2. Expand Bluetooth.
3. Right-click the main Bluetooth adapter.
4. Select Uninstall device.
5. Confirm the removal.
6. Restart the computer.

Windows normally attempts to reinstall the driver after restart. If it does not:

1. Open Device Manager.
2. Select Action > Scan for hardware changes.
3. Run the manufacturer’s downloaded driver installer.
4. Restart again.

Do not uninstall every paired headphone, mouse, phone, and Bluetooth service entry. Remove the main radio adapter only.

14. Roll Back the Bluetooth Driver

Use this when Bluetooth disappeared immediately after a driver or Windows update.

1. Open Device Manager.
2. Expand Bluetooth.
3. Right-click the adapter.
4. Select Properties.
5. Open the Driver tab.
6. Select Roll Back Driver if available.
7. Choose an appropriate reason.
8. Restart Windows.

Microsoft recommends driver rollback when Bluetooth worked before a recent update.

If the button is greyed out, Windows no longer has the earlier driver package. Download a previous compatible driver from the computer manufacturer if it provides one.

Avoid installing an old driver from an unknown source.

15. Remove a Recent Windows Update

If Bluetooth vanished immediately after a Windows update and driver repair did not help:

1. Open Settings.
2. Select Windows Update.
3. Open Update history.
4. Select Uninstall updates.
5. Identify the update installed just before the problem began.
6. Remove it if Windows permits.
7. Restart the computer.

Do not remove security updates casually. Confirm the timing and try driver rollback first.

Windows may reinstall the update later. Check the manufacturer’s website for a corrected Bluetooth driver before allowing the same update to return.

16. Use System Restore

System Restore can return drivers, services, registry settings, and Windows components to an earlier state without deleting personal documents.

1. Search for Create a restore point.
2. Open it.
3. Select System Restore.
4. Choose a restore point created before Bluetooth disappeared.
5. Review the affected programs.
6. Complete the restoration.

Applications and drivers installed after the restore point may be removed. Back up important work first.

Use this option only when the disappearance began after a clear software or driver change.

17. Turn Off Fast Startup

Fast Startup can preserve a faulty hardware state between shutdowns.

1. Open Control Panel.
2. Select Hardware and Sound.
3. Open Power Options.
4. Select Choose what the power buttons do.
5. Select Change settings that are currently unavailable.
6. Clear Turn on fast startup.
7. Save the changes.
8. Shut down and start the computer.

If Bluetooth remains stable afterward, a driver or firmware problem may have prevented the adapter from initialising correctly during hybrid startup.

Fast Startup is not a universal cause. You can re-enable it if disabling it makes no difference.

18. Adjust Bluetooth Power Management

If Bluetooth disappears after sleep or when the laptop runs on battery, Windows may be powering down the adapter.

1. Open Device Manager.
2. Expand Bluetooth.
3. Right-click the main adapter.
4. Select Properties.
5. Open the Power Management tab if present.
6. Clear Allow the computer to turn off this device to save power.
7. Select OK.
8. Restart Windows.

Not every driver exposes this tab.

You may also need an updated chipset or Bluetooth driver to resolve sleep-state failures properly. Disabling power saving can increase battery consumption slightly.

19. Check the USB Controller

On many systems, the Bluetooth portion of a combined wireless card communicates internally through USB. A USB controller fault can therefore make Bluetooth disappear while Wi-Fi continues working.

Open Device Manager and expand Universal Serial Bus controllers. Look for:

• Unknown USB Device
• A warning symbol
• USB controller errors

Restart the computer and install chipset or USB controller drivers from the computer manufacturer.

Do not uninstall all USB controllers while using a USB keyboard and mouse unless you understand how they will be restored. Start with model-specific chipset updates.

20. Install Chipset and Firmware Updates

The Bluetooth driver may be correct while the chipset, BIOS, or system firmware prevents the wireless card from being detected.

Use the official computer or motherboard support page to check for:

• Chipset drivers
• Serial IO drivers
• USB controller drivers
• Wireless radio packages
• BIOS or UEFI updates
• System firmware updates

Read the manufacturer’s BIOS instructions carefully. Keep a laptop connected to power and do not interrupt a firmware update.

Do not install a BIOS intended for another model.

21. Check Bluetooth in BIOS or UEFI

Some PCs allow internal wireless devices to be enabled or disabled in firmware.

Look for settings such as:

• Wireless device
• Bluetooth
• Internal radio
• WLAN and Bluetooth
• Onboard devices

Only change a setting when you understand it. Record the original value before making adjustments.

If Bluetooth is disabled in firmware, Windows cannot make the toggle appear. If no related setting exists, leave the BIOS unchanged.

22. Run SFC and DISM

Damaged Windows system files can affect Settings, services, Device Manager, and driver installation.

Open Terminal as administrator and run:

sfc /scannow

Wait for the scan to finish. Then run:

DISM /Online /Cleanup-Image /RestoreHealth

Restart Windows after both commands complete.

These tools repair Windows components. They do not replace a missing manufacturer Bluetooth driver or repair failed hardware.

If SFC reports that Windows Resource Protection could not complete the operation, see Windows Resource Protection error for the appropriate repair steps.

23. Test in Safe Mode

Safe Mode can reveal whether a third-party utility, VPN, security program, device manager, or hardware-control application is interfering.

Boot into Safe Mode and check Device Manager. Bluetooth functionality may be limited there, but the presence or absence of the hardware can still provide useful information.

If the adapter appears normally in Safe Mode but disappears during a standard startup, investigate:

• Third-party driver tools
• Laptop optimisation utilities
• Security applications
• Recent startup programs
• Device-control policies

Follow how to boot Windows 11 in Safe Mode for the available startup methods.

24. Repair Windows 11 Without Deleting Files

Use a Windows repair reinstall only after driver, service, update, firmware, and hardware checks have failed.

Supported Windows 11 versions may offer:

Settings > System > Recovery > Fix problems using Windows Update > Reinstall now

Microsoft says this option reinstalls the current Windows version to repair system components. Availability can depend on the Windows edition, update level, and device management.

Back up important files before any major repair.

This method will not fix a failed Bluetooth card. Confirm that the adapter is detected at the firmware or hardware level first.

Bluetooth Missing From Device Manager

If there is no Bluetooth category:

1. Select View > Show hidden devices.
2. Check Network adapters, Other devices, and USB controllers.
3. Select Action > Scan for hardware changes.
4. Perform a full shutdown.
5. Install Bluetooth and chipset drivers from the manufacturer.
6. Check BIOS or UEFI wireless settings.
7. Test a USB Bluetooth adapter if available.

If a USB adapter works while the internal adapter never appears, the internal card, its connection, or its firmware may be faulty.

Bluetooth Toggle Missing From Windows 11 Settings

When the toggle is missing:

1. Turn off Airplane mode.
2. Restart Windows.
3. Run the Get Help troubleshooter.
4. Restart Bluetooth Support Service.
5. Enable or update the adapter in Device Manager.
6. Install the manufacturer’s Bluetooth driver.

A missing toggle usually means Windows cannot currently enable a detected Bluetooth radio or cannot detect one at all.

Bluetooth Disappeared After Windows 11 Update

Try this order:

1. Restart the computer.
2. Check optional driver updates.
3. Install the current Bluetooth driver from the PC manufacturer.
4. Roll back the adapter driver if the problem began immediately.
5. Uninstall the recent update only when the timing is clear.
6. Use System Restore if a suitable restore point exists.

Avoid factory resetting Windows for a single driver problem.

Bluetooth Disappears After Sleep

This pattern normally points to power management, firmware, or a driver that does not resume correctly.

1. Install current Bluetooth and chipset drivers.
2. Disable the adapter’s power-management option.
3. Turn off Fast Startup for testing.
4. Install BIOS or firmware updates from the manufacturer.
5. Use Hibernate or shut down temporarily if sleep repeatedly triggers the fault.

When the Problem May Be Hardware

Hardware becomes more likely when:

• Bluetooth never appears in Device Manager or BIOS.
• The correct drivers refuse to detect compatible hardware.
• Both Wi-Fi and Bluetooth disappear after a drop, repair, or liquid exposure.
• Device Manager shows a persistent hardware error.
• The internal adapter works only when the laptop is moved or pressed.
• A USB Bluetooth adapter works normally but the internal one does not.

Before paying for repair, check the computer’s original specifications. Some desktop PCs and budget laptops do not include Bluetooth unless a wireless card or USB adapter is installed.

A qualified technician can inspect the internal card, antenna leads, motherboard connection, and power delivery.

Frequently Asked Questions

Why did Bluetooth disappear from Windows 11?

Windows may have stopped detecting the Bluetooth adapter because of Airplane mode, a driver problem, a disabled service, power management, a recent update, firmware, or failed hardware.

How do I get Bluetooth back on Windows 11?

Restart Windows, turn off Airplane mode, run the Bluetooth troubleshooter, show hidden devices in Device Manager, enable the adapter, and install the latest model-specific Bluetooth driver.

Why is there no Bluetooth toggle in Windows 11?

The toggle disappears when Windows cannot detect or enable a Bluetooth radio. Check Device Manager, Bluetooth Support Service, drivers, Airplane mode, and BIOS settings.

Why is Bluetooth missing from Device Manager?

The adapter may be hidden, missing its driver, disabled in BIOS, stuck in a failed power state, connected through a malfunctioning USB controller, or physically faulty.

Can Windows Update remove Bluetooth?

An update can install an incompatible driver or expose an existing compatibility problem. Install the manufacturer’s current driver or roll back the Bluetooth driver when the issue begins immediately after an update.

Will reinstalling the Bluetooth driver remove paired devices?

It may require you to pair some devices again. Download the correct replacement driver before uninstalling the adapter.

Does network reset restore missing Bluetooth?

Network reset may help certain network configurations, but it is not the best first fix when the Bluetooth adapter is absent from Device Manager. Repair hardware detection and the Bluetooth driver first.

Can I add Bluetooth to a PC that does not have it?

Yes. A compatible USB Bluetooth adapter is usually the simplest option. Install the manufacturer’s driver if Windows does not configure it automatically.

Should I factory reset Windows 11?

Not for this problem alone. Try the troubleshooter, driver reinstall, manufacturer packages, rollback, firmware, system-file repair, and a repair reinstall first. If a full reset eventually becomes necessary, read Windows 11 factory reset from boot and back up your files.

Begin with the simple distinction between a missing Quick Settings tile and an undetected Bluetooth adapter. If Bluetooth is present in Device Manager, enable, update, or reinstall it. If the category is completely absent, focus on full power reset, hardware scan, model-specific Bluetooth and chipset drivers, BIOS settings, and possible hardware failure.
