Bluetooth not working in Windows 11: how to fix it

Published By helps.wiki editorial team

Windows 11 Bluetooth problems usually come from a switched-off radio, a device that needs re-pairing, or a driver that broke after an update. Start with the quick checks and the built-in troubleshooter, then update or reinstall the Bluetooth driver.

What it means

There is no single error code here. "Bluetooth not working" means Windows 11 can't find, switch on or use the Bluetooth radio, or it can't connect to one particular device.

The cause is often simple. The fixes below go from the quickest and safest to the more involved, so work through them in order and stop when Bluetooth comes back.

This article covers the general case. Microsoft also has separate pages for narrower problems such as no sound, only one audio channel, and devices that keep disconnecting. Those are not covered here.

Symptoms and causes

You are likely dealing with this problem if:

  • The Bluetooth tile is missing from Quick Settings, or Settings > Bluetooth & devices has no toggle, or the toggle is greyed out.
  • The Bluetooth adapter or the whole Bluetooth section is missing from Device Manager.
  • Devices won't pair or connect, or never show up when Windows searches.
  • Devices that worked before stopped working after an update.

The usual causes, most common first:

Outdated or incompatible driver
Microsoft calls this one of the most common causes. It often appears after a Windows upgrade or update.
Radio switched off
Airplane mode is on, Bluetooth is toggled off, or a laptop's physical switch or Fn key has disabled the radio.
Problem with the device itself
The device is off, discharged, out of range, or has a stale pairing. Unshielded devices plugged into USB 3.0 ports can also cause interference.
Discovery setting hides devices
If Bluetooth device discovery is set too narrowly, nearby devices may not be listed.
Stopped services, a recent update or firmware
Microsoft lists stopped system services, a recent Windows update and firmware or BIOS issues among the reasons Bluetooth can vanish.
Hardware fault or no Bluetooth at all
The adapter may have failed, or the PC may not have Bluetooth hardware.
Fast Startup leaving the radio in a bad state
Only a third-party source mentions this, so treat it as a lower-probability cause.

How to fix it

Work through these in order. They start with the quickest, safest checks and move to deeper repairs; stop as soon as the problem is gone.

1.Do the quick checks

Easy

A switched-off radio or a flat device accounts for many cases and takes a minute to rule out.

  1. Press WinA to open Quick Settings and make sure Airplane mode is off.
  2. Turn Bluetooth on with the Quick Settings tile, or in Settings > Bluetooth & devices. On a laptop, also check for a physical wireless switch or an Fn key that disables the radio.
  3. Make sure the device you want is on, charged and close to the PC. Turn it off and on again.
  4. If the device is on a USB 3.0 port or near one, move it to another port or further away, since interference from unshielded devices can disrupt Bluetooth.

2.Do a full shutdown, not a restart

Easy

Microsoft suggests this when Bluetooth has disappeared. It resets the hardware more thoroughly than a restart.

  1. Hold Shift and select Start > Power > Shut down.
  2. Wait one minute, then turn the PC on again.

3.Run the Bluetooth troubleshooter

Easy

Microsoft recommends the Get Help troubleshooter first on Windows 11. It checks common settings automatically.

  1. Open the Get Help Bluetooth troubleshooter from Microsoft at aka.ms/GetHelp-BluetoothTroubleshooter and follow the prompts.
  2. Alternatively, go to Settings > System > Troubleshoot > Other troubleshooters, find Bluetooth and select Run.

4.Set Bluetooth device discovery to Advanced

Easy

If a device never appears while searching, the discovery setting may be hiding it.

  1. Open Settings > Bluetooth & devices > Devices.
  2. Under Device settings, set Bluetooth devices discovery to Advanced.

5.Remove the device and pair it again

Easy

A stale pairing can stop a device connecting even though both sides look fine.

  1. Go to Settings > Bluetooth & devices > Devices.
  2. Select More options (the three dots) next to the device, then Remove device, then Yes.
  3. Put the device in pairing mode and add it again with Add device.

6.Update the Bluetooth driver

Moderate

An outdated or incompatible driver is one of the most common causes, especially after an update.

  1. Right-click Start and open Device Manager. Expand Bluetooth.
  2. Right-click your Bluetooth adapter (it may be named something like Radio), select Update driver, then Search automatically for drivers. Restart if prompted.
  3. Also check Settings > Windows Update > Advanced options > Optional updates for driver or firmware updates and install any that relate to Bluetooth.
  4. If nothing is found, download the driver from the PC or adapter maker's own website. Run the installer if it is an .exe. For .inf or .sys files, use Update driver > Browse my computer for drivers.
  5. While on the maker's site, check for BIOS, UEFI or firmware updates for your model too.

7.Uninstall and reinstall the adapter

ModerateChanges settings

This forces Windows to rebuild the adapter's driver entry, which helps when the driver is corrupted.

Before you start: Make sure you can get a driver again first: Windows normally reinstalls it on startup, but note your PC or adapter model in case you need the maker's driver.

  1. In Device Manager, expand Bluetooth, right-click the adapter and select Uninstall device, then Uninstall.
  2. Shut down the PC, wait a minute, then turn it on. Windows should detect the adapter and reinstall it.
  3. If it doesn't come back, open Device Manager and select Action > Scan for hardware changes.

8.Restart the Bluetooth Support Service

Moderate

A stopped service can leave Bluetooth unavailable. This step comes from a third-party article, not Microsoft's pages.

  1. Press WinR, type the command below and press Enter.
    Command Prompt
    services.msc
  2. Open Bluetooth Support Service, select Stop, then Start.
  3. If it won't stay running, set Startup type to Automatic and apply the change.

9.Turn off Fast Startup

Moderate

Only one third-party source links Fast Startup to Bluetooth failures, so try this late.

  1. Open Control Panel > Power Options > Choose what the power button does.
  2. Select Change settings that are currently unavailable.
  3. Untick Turn on fast startup and select Save changes.

10.Check whether the PC has Bluetooth at all

Easy

If Device Manager shows nothing Bluetooth-related, the hardware may simply be absent or dead.

  1. Open Device Manager and look for a Bluetooth section. Also check under Network adapters for a Bluetooth entry.
  2. If neither exists after the reinstall steps above, the PC probably has no working Bluetooth. Use an external USB Bluetooth adapter, or contact the PC manufacturer if the PC should have Bluetooth built in.

Check that it worked

  • The Bluetooth tile appears in Quick Settings and the toggle in Settings > Bluetooth & devices can be switched on.
  • Device Manager lists a Bluetooth section with your adapter and no warning icon.
  • Your device appears in the list and shows as connected.

If it still fails

  • Contact the PC manufacturer for a model-specific Bluetooth driver and BIOS or firmware update, since many drivers are OEM-specific.
  • If the adapter is missing everywhere, even after a full shutdown and reinstall, it may have failed. A USB Bluetooth adapter is a simple workaround.
  • For problems limited to audio, such as no sound or one channel, or devices that keep disconnecting, see Microsoft's dedicated Bluetooth articles.
