Windows 11 Bluetooth Not Working? 7 Ways to Fix It

Your earbuds connect to your phone without trouble, but your Windows 11 laptop will not find them. Or the Bluetooth toggle has disappeared from Quick Settings entirely. Bluetooth problems on Windows usually come down to one of four things: Bluetooth is turned off somewhere, the device is not in pairing mode, an old pairing record is getting in the way, or the Bluetooth driver has stopped working.

This guide goes through the fixes from quickest to most involved. It is written for Windows 11 version 24H2 and later, and the menu paths follow Microsoft Support's article "Fix Bluetooth problems in Windows." Some laptops label things slightly differently, but the paths below match a standard Windows 11 install.

Quick summary

  • Check first: Airplane mode is off, Bluetooth is on, and the device is charged and in pairing mode.
  • Device will not show up: set Bluetooth devices discovery to Advanced, then remove and re-pair the device.
  • Bluetooth toggle is missing: the adapter or its driver is the problem. Update or reinstall it in Device Manager.
  • Connects but keeps dropping: move the device away from USB 3.0 ports and turn off power saving for the adapter.

Find your symptom

Different symptoms point to different causes. Find the row closest to what you are seeing and start at that step. If none fit, start at Step 1.

What you seeLikely causeGo to
Bluetooth is on, but the device never appears in the listDevice not in pairing mode, or discovery set to DefaultStep 2, Step 3
Device shows as "Paired" but will not connectOld or broken pairing recordStep 4
Bluetooth worked yesterday, now nothing connectsBluetooth service stopped, or a driver problem after an updateStep 5, Step 6
No Bluetooth toggle in Quick Settings or SettingsAdapter disabled, missing driver, or Airplane modeStep 1, Step 6
Audio cuts out or the mouse lags, then disconnectsInterference or power savingStep 7

Step 1: Check Airplane mode and the Bluetooth switch

Airplane mode turns off Bluetooth along with Wi-Fi, and it is easy to switch on by accident with a keyboard shortcut. Some laptops also have a physical wireless switch or a function key (often marked with an airplane or antenna icon).

  1. Select the network, sound, or battery icon at the right end of the taskbar to open Quick Settings.
  2. If Airplane mode is highlighted, select it to turn it off.
  3. Select the Bluetooth tile so it is highlighted.
  4. If you do not see a Bluetooth tile, go to Start > Settings > Bluetooth & devices and turn on Bluetooth there.

If Bluetooth is already on, turn it off, wait about ten seconds, and turn it back on. This alone clears a stuck connection more often than you might expect.

If there is no Bluetooth switch anywhere in Settings, check that your PC actually has Bluetooth. Most laptops do, but many desktop PCs do not unless the motherboard includes it or you add a USB Bluetooth adapter. The product specifications on the manufacturer's website will tell you. If it should have Bluetooth, go to Step 6.

Step 2: Put the device in pairing mode

A Bluetooth device that is already connected to another phone or tablet usually will not show up on your PC. It has to be in pairing mode, which normally means a blinking light.

  • Earbuds with a case: put the earbuds in the case, open the lid, and press and hold the button on the case until the light blinks.
  • Headphones and speakers: press and hold the power or Bluetooth button for several seconds until you hear a tone or see a blinking light.
  • Mice and keyboards: look for a small button labeled "Connect" or with a Bluetooth symbol on the bottom.

Also make sure the device is charged and within a few feet of the PC. If it is still connected to your phone, turn Bluetooth off on the phone for now. Then, on the PC, go to Start > Settings > Bluetooth & devices, select Add device, and choose Bluetooth.

Step 3: Turn on advanced device discovery

By default, Windows 11 hides some device types from the Add device list to keep it short. Microsoft recommends switching discovery to Advanced when a device does not appear.

  1. Go to Start > Settings > Bluetooth & devices > Devices.
  2. Scroll down to Device settings.
  3. Set Bluetooth devices discovery to Advanced.
  4. Go back, select Add device > Bluetooth, and wait about 30 seconds with the device in pairing mode.

Step 4: Remove the device and pair it again

If the device appears as "Paired" or "Not connected" but will not connect, the saved pairing information may be out of date. This often happens after a firmware update on the earbuds or after the device was paired with another computer.

  1. Go to Start > Settings > Bluetooth & devices > Devices.
  2. Find the device, select More options (the three dots) next to it, and select Remove device, then Yes.
  3. Put the device back in pairing mode.
  4. Select Add device > Bluetooth and choose the device from the list.

Good to know

  • Many earbuds also keep their own list of paired devices. If re-pairing on the PC does not help, reset the earbuds using the manufacturer's instructions (often holding the case button for 10 to 15 seconds), then pair again.
  • If a pairing PIN appears, check that the same number shows on both screens before you confirm.

Step 5: Restart the Bluetooth Support Service

Windows uses a background service to discover and manage Bluetooth devices. If it has stopped, nothing will connect even though Bluetooth looks turned on. You can also run the built-in troubleshooter first: go to Start > Settings > System > Troubleshoot > Other troubleshooters and select Run next to Bluetooth. On recent versions this opens the Get Help app, which runs the same checks.

If that does not fix it, restart the service manually:

  1. Press Windows + R, type services.msc, and press Enter.
  2. Scroll down and double-click Bluetooth Support Service.
  3. Set Startup type to Automatic.
  4. If Service status says Running, select Stop and then Start. If it says Stopped, select Start.
  5. Select OK, then try connecting the device again.

Step 6: Update or reinstall the Bluetooth driver

If Bluetooth stopped working right after a Windows update, or the Bluetooth toggle has vanished, the driver is the most likely cause.

Update the driver

  1. Select Search on the taskbar, type Device Manager, and open it.
  2. Expand Bluetooth. The adapter is usually the entry with "Wireless," "Radio," or the chip maker's name (Intel, Realtek, MediaTek, Qualcomm) in it.
  3. Right-click the adapter, select Update driver, then Search automatically for drivers.
  4. Restart the PC if Windows asks you to.

If Windows says the best driver is already installed, download the latest Bluetooth driver for your exact model from the PC manufacturer's support site (Dell, HP, Lenovo, ASUS, and others all list drivers by model or serial number) and install it.

Reinstall the driver

  1. In Device Manager, right-click the Bluetooth adapter and select Uninstall device, then Uninstall.
  2. Go to Start > Power > Shut down. Wait a few seconds, then turn the PC back on. Windows reinstalls the driver during startup.
  3. If the adapter does not come back, open Device Manager and select Action > Scan for hardware changes.

Be careful

  • Before uninstalling, download the manufacturer's driver first if you can. If Windows cannot reinstall the driver on its own, you will need that file, and you may not have Bluetooth until it is installed.
  • If the Bluetooth section is missing from Device Manager entirely, select View > Show hidden devices. A missing adapter can also mean it is turned off in the BIOS or UEFI settings, or that the wireless card has failed.

Step 7: Stop Windows from turning off the adapter

On many laptops, Windows can switch off the Bluetooth adapter to save battery. When that happens, devices disconnect after the PC has been idle or wakes from sleep.

  1. In Device Manager, expand Bluetooth and double-click the adapter.
  2. Open the Power Management tab, if it is there.
  3. Clear Allow the computer to turn off this device to save power and select OK.

Not every adapter has a Power Management tab. If yours does not, this setting is controlled by the driver, and Step 6 is the better fix.

Interference can cause drop-outs too. USB 3.0 ports and devices, such as external drives plugged into the front of a PC, can disrupt the 2.4 GHz signal Bluetooth uses. Move the Bluetooth device closer to the PC, or plug USB 3.0 devices into ports farther from where the Bluetooth adapter or receiver sits.

Frequently asked questions

Q. Why did the Bluetooth option disappear from Settings?

Usually the adapter is disabled, its driver failed to load, or Airplane mode is on. Check Airplane mode first, then look in Device Manager under Bluetooth for a warning icon or a disabled adapter (right-click it and select Enable device). If the adapter is not listed at all, follow the reinstall steps in Step 6.

Q. My Bluetooth headphones connect but there is no sound.

Windows may still be sending audio to the laptop speakers. Open Quick Settings, select the arrow next to the volume slider, and choose your headphones. You can also set them in Start > Settings > System > Sound under Output.

Q. Do I need a Bluetooth adapter for my desktop PC?

If Bluetooth & devices has no Bluetooth switch and Device Manager has no Bluetooth section even with hidden devices shown, your PC probably has no Bluetooth hardware. A small USB Bluetooth adapter adds it, and Windows 11 installs drivers for most of them automatically.

Q. Will removing a device delete anything on it?

No. Removing a device only deletes the pairing record on your PC. Your files, music, and the device's own settings are not affected. You just have to pair it again.

Summary: the order to remember

  1. Turn off Airplane mode and turn Bluetooth off and back on.
  2. Put the device in pairing mode and set discovery to Advanced.
  3. Remove the device and pair it again.
  4. Run the troubleshooter and restart the Bluetooth Support Service.
  5. Update or reinstall the Bluetooth driver, then turn off power saving for the adapter.

The first three steps take only a few minutes and fix most cases. If the Bluetooth adapter is missing from Device Manager even after a full shutdown and a hardware scan, contact your PC manufacturer, since the wireless card itself may need service.
