How to Fix Bluetooth Not Pairing or Connecting in Windows 11

If Bluetooth is visible in Windows 11 but a mouse, keyboard, headphones, controller, or phone refuses to pair, the problem is usually easier to solve than a missing Bluetooth adapter. Pairing failures commonly come from the accessory not being in discovery mode, an old saved pairing, low battery, interference, or a driver problem.

1. Confirm Bluetooth is actually on

Open Settings > Bluetooth & devices and make sure Bluetooth is enabled. If the switch is completely missing, use the separate missing-Bluetooth troubleshooting path because Windows may not be detecting the adapter.

2. Put the accessory into pairing mode again

Do not assume a flashing LED always means the device is discoverable. Check the accessory manual and put it into its dedicated pairing mode. If it was previously paired to a phone, tablet, console, or another PC, disconnect it there first.

Move the accessory close to the computer while pairing. Microsoft also notes that some unshielded USB 3.0 devices can interfere with nearby Bluetooth devices, so temporarily move USB devices away if the connection is unstable.

3. Charge the device

Low battery can allow an accessory to power on but fail during pairing. Fully charge rechargeable headphones, controllers, and keyboards, then power-cycle them before trying again.

4. Remove the old pairing and add the device again

1. Open Settings > Bluetooth & devices.
2. Find the device.
3. Select the three-dot menu and choose Remove device.
4. Select Add device > Bluetooth.
5. Choose the accessory when it appears.

If Windows asks for a PIN, use the code supplied by the device manufacturer rather than guessing.

5. Run the Bluetooth troubleshooter

Open Get Help and search for the Bluetooth troubleshooter. On Windows 11, Microsoft recommends the automated Get Help diagnostics as an early troubleshooting step.

6. Update Windows and the Bluetooth driver

Open Settings > Windows Update and install available updates. Then check Windows Update > Advanced options > Optional updates for a Bluetooth driver when available.

If the PC manufacturer provides a newer Bluetooth or wireless package for your model, prefer that package when the generic Windows driver is causing problems.

7. Restart Bluetooth before reinstalling anything

Turn Bluetooth off in Settings, wait about ten seconds, turn it back on, and restart the PC. Only move to uninstalling the Bluetooth adapter in Device Manager if the simpler steps fail and you have a driver available if Windows cannot reinstall it automatically.

If one accessory still fails while other Bluetooth devices work, the problem is more likely with that accessory than with Windows.

Check whether the problem is pairing or reconnecting

A device that has never paired needs discovery mode and may require confirmation or a PIN. A device that paired successfully in the past but no longer reconnects is more likely to have a stale pairing record, battery issue, competing connection, or driver problem. Knowing which case you have helps avoid unnecessary resets.

Test another Bluetooth accessory

If possible, pair a second known-good Bluetooth device with the PC. If the second device works, Windows and the Bluetooth radio are probably functioning and the original accessory deserves closer attention. If nothing pairs, focus on the PC adapter, driver, firmware, and Windows updates.

Likewise, try the problem accessory with another phone or computer. A two-way test is faster than repeatedly reinstalling Windows drivers for a headset that is actually failing.
