Quick answer: Most Bluetooth failures in Windows 11 come from one of four things: Bluetooth or Airplane mode set the wrong way, a device that isn’t in pairing mode or is too far away, a stale pairing, or the adapter driver. Check those, run Microsoft’s troubleshooter in Get Help, then install the newest update, which carries several autumn 2026 Bluetooth fixes.

Applies to Windows 11 24H2 and 25H2; 26H2 should match, though we haven’t confirmed every path. Windows 10 Settings pages differ.
Match your symptom
| What you see | Likely cause | Where to start |
|---|---|---|
| No Bluetooth tile or toggle anywhere | Adapter off, disabled or without a driver | Bluetooth toggle missing section |
| Toggle won’t stay on | Airplane mode, driver or firmware | Quick checks, Fix 5, Fix 7 |
| Your device never shows up in the list | Not in pairing mode, out of range, or filtered out | Fix 3 and Fix 4 |
| Paired but drops or says not connected | Old pairing, interference, low battery | Fix 3, Fix 9 |
| Connected but silent | Wrong output or audio format | No sound section |
| Adapter under Other devices with a yellow mark | Driver not installed | Fix 6 |
Quick checks first
- Charge the device, keep it close and put it in pairing mode (check its manual; every brand differs).
- Press Win + A and turn Airplane mode off; it cuts the Bluetooth radio too.
- Open Settings > Bluetooth & devices and set Bluetooth to On. A line saying the PC is discoverable means the radio works.
- On laptops, check any wireless switch or Fn key.
- Keep away from USB 3.0 drives and hubs, which Microsoft says can interfere.
Fix 1: Run the Bluetooth troubleshooter
Microsoft’s first recommendation on Windows 11 is the Bluetooth troubleshooter in Get Help. Opening aka.ms/GetHelp-BluetoothTroubleshooter launches it.
Microsoft also lists Settings > System > Troubleshoot > Other troubleshooters > Bluetooth > Run; on current builds it may just open Get Help.
Fix 2: Toggle Bluetooth, then shut down fully
Switch Bluetooth off in Settings > Bluetooth & devices, wait about 10 seconds and switch it on again. If that changes nothing, hold Shift while you select Start > Power > Shut down. Leave the PC off for a minute, then start it.
With Fast Startup on, a normal shutdown keeps part of the system state, so a stuck radio can stay stuck. Microsoft advises Shut down, not Restart, when Bluetooth disappears.
Fix 3: Remove the device and pair it again
A stale pairing record often stops a known device connecting. Go to Settings > Bluetooth & devices > Devices, select the three-dot More options button next to the device, choose Remove device and confirm with Yes.
Put the device back into pairing mode. Open Quick Settings, select the arrow on the Bluetooth tile (Manage Bluetooth devices), and pick your device under New devices. Swift Pair accessories instead show a notification with a Connect button.
Fix 4: Show all devices while searching
Windows hides some device types by default. Under Settings > Bluetooth & devices > Devices, find Device settings and set Bluetooth devices discovery to Advanced, then search again.
Fix 5: Install the newest Windows update
Open Settings > Windows Update and select Check for updates. If nothing arrives, see how to force Windows Update to check and install updates. Then open Advanced options > Optional updates, where maker drivers and firmware often wait.
The September 22, 2026 preview KB5124010 fixed a toggle that showed On while the radio was actually off, a 0x139 crash while streaming Bluetooth audio, some headset microphone problems and LE Audio reliability. Those fixes reached all PCs with the October 13, 2026 update, so just install the newest one. As of early November 2026, Microsoft lists no open Bluetooth known issue.
Fix 6: Update or roll back the driver
Right-click Start and open Device Manager. Expand Bluetooth, right-click the adapter (often named Radio or after the chip maker) and select Update driver > Search automatically for drivers.
If nothing is found, install the maker’s driver for your model; a bare .inf file goes in through Browse my computer for drivers. If trouble began after a driver update, use the Properties > Driver tab’s Roll Back Driver.
No Bluetooth category? Check Other devices for a yellow-marked device and see our Code 28 guide for devices whose drivers aren’t installed. Avoid third-party driver updaters.
Fix 7: Reinstall the adapter
In Device Manager, right-click the Bluetooth adapter, choose Uninstall device and confirm, then shut down and power on. If it doesn’t return, select Action > Scan for hardware changes.
Warning: if the dialog offers to remove the driver too (wording varies), tick it only when you have the maker’s driver ready.
Fix 8: Check the Bluetooth Support Service
Press Win + R, type services.msc and open Bluetooth Support Service (bthserv). Microsoft says it handles discovery and pairing, and stopping it can make paired devices fail and hide new ones. Manual startup is the default. Choose Start, or Restart if it’s running. Setting it to Automatic is an unofficial tweak.
Disabled on a work PC? Policy may have done that, so ask IT. For headset call audio, restarting Bluetooth Audio Gateway Service may help (not a documented fix).
Fix 9: Power settings and USB dongles
Community fixes, not Microsoft guidance, that may help an adapter that drops after sleep: on the adapter’s Power Management tab (not always present), untick Allow the computer to turn off this device to save power; or turn off Fast Startup in Control Panel > Power Options > Choose what the power buttons do.
With a USB dongle, try a USB 2.0 port or a short extension cable. A Bluetooth mouse that moves but won’t click has its own set of checks.
Bluetooth toggle missing in Windows 11
No tile or switch means Windows can’t see a working adapter. In order:
- Do the Shift + Shut down cold start and check Airplane mode.
- In Device Manager, select View > Show hidden devices. If the adapter is disabled, choose Enable device.
- Under Other devices, it needs a driver (Fix 6).
- Not listed at all: install optional updates and the maker’s BIOS/UEFI or firmware updates. Some PCs have a Bluetooth option in the BIOS.
- Many desktops have no Bluetooth; a USB adapter fixes that.
Device is connected but there’s no sound
- Pick the output: the arrow by the Quick Settings volume slider, or Settings > System > Sound > Output.
- Headsets with a mic may list a stereo output and a hands-free one for calls, which sounds thin. Names vary, and LE Audio headsets may differ.
- Reset the format: in Settings > Bluetooth & devices > Devices, open the connected device, then Advanced sound properties and set the output format to 2 channels, 16 bit, 48000 Hz (DVD Quality).
- Pair again (Fix 3) and update the driver (Fix 6).
- Confirm the device supports A2DP, the stereo audio profile.
Headset on a USB dongle instead? That may be a different 2026 issue: see USB audio device shows Code 10 in Windows 11.
When nothing works
Try the device on a phone: if it fails there too, the device is at fault. System Restore can undo a bad driver change. Network reset, which some guides suggest, resets Wi-Fi and Ethernet, not Bluetooth. For a dead laptop adapter, contact the maker or use a USB adapter.
