Windows "Make sure your Bluetooth device is still discoverable" fix

Short answer

Windows found your Bluetooth device but lost it before pairing finished, usually because the device left pairing mode, is still connected to a phone, or has a stale old pairing on the PC. Remove the device in Settings > Bluetooth & devices, turn Bluetooth off and on, put the device back in pairing mode (usually a long press until the light flashes), then choose Add device again.

What this message means

Windows shows this message when pairing starts but the device stops answering before the connection is finished. The device appeared in the list, so the PC's Bluetooth radio works, but the handshake timed out or was refused. Most devices only stay discoverable for 30 to 120 seconds, and many headphones, speakers and mice stop advertising as soon as they reconnect to a phone or another computer they already know. A leftover pairing record on the PC, a stuck Bluetooth service, or a faulty Bluetooth driver can also break the handshake, so the device gets blamed even when the fault is on the Windows side.

Common causes

CauseHow to tell
The device left pairing mode before Windows finishedThe status light on the device stopped flashing (or went solid or off) by the time you clicked it in the list, or the device disappears from the Add a device list after a minute.
The device reconnected to a phone, tablet or other PCYour phone shows the headphones or speaker as connected, or audio starts playing from the phone instead of the PC.
An old or broken pairing record for the same device on the PCThe device already appears under Bluetooth & devices (often as Paired but not Connected), or you paired it with this PC before a reset or Windows update.
Bluetooth Support Service or the Bluetooth stack is stuckEvery device fails with the same message, including ones that paired fine before, and a full restart fixes it temporarily.
Outdated, corrupted or wrong Bluetooth adapter driverDevice Manager shows a yellow warning icon on the adapter under Bluetooth, or the problem started right after a Windows or driver update.
Weak signal or radio interferencePairing works when the device is right next to the PC but fails across the room, or fails when a USB 3.0 drive or hub is plugged in near the Bluetooth adapter or dongle.

How to fix it

1. Put the device back in pairing mode and pair right away

  1. Disconnect the device from your phone or other computers, or turn Bluetooth off on those devices for now.
  2. Turn the Bluetooth device off and on again, and charge it or replace its batteries if they are low.
  3. Put it in pairing mode (on most headphones and speakers, hold the power or Bluetooth button for 5 to 7 seconds until the light flashes, often blue and red). Check the manufacturer's manual if you are unsure.
  4. Keep the device within about 1 metre (3 feet) of the PC.
  5. In Windows 11 go to Start > Settings > Bluetooth & devices > Add device > Bluetooth. In Windows 10 go to Start > Settings > Devices > Bluetooth & other devices > Add Bluetooth or other device > Bluetooth.
  6. Select the device as soon as it appears, while its light is still flashing.

2. Remove the old pairing and toggle Bluetooth

Windows 11 and Windows 10 (menu paths differ as noted)

  1. Windows 11: Start > Settings > Bluetooth & devices > Devices, click the three dots (More options) next to the device, then Remove device. Windows 10: Start > Settings > Devices > Bluetooth & other devices, select the device, then Remove device.
  2. On the Bluetooth device, clear its pairing memory if it has a reset option (see the manual; often a long press of two buttons together).
  3. Turn the Bluetooth switch off on the same Settings page, wait 10 seconds, and turn it back on.
  4. Make sure Airplane mode is off in Quick Settings (Windows 11) or Action Center (Windows 10).
  5. Put the device in pairing mode and add it again.

3. Show all nearby devices (Windows 11) or allow discovery (Windows 10)

Windows 11 and Windows 10

  1. Windows 11: Start > Settings > Bluetooth & devices > Devices, scroll to Device settings, and set Bluetooth devices discovery to Advanced. This lists devices that the Default setting hides.
  2. Windows 10: Start > Settings > Devices > Bluetooth & other devices > More Bluetooth options, open the Options tab and tick Allow Bluetooth devices to find this PC, then click OK.
  3. Try Add device again with the device in pairing mode.

4. Restart the Bluetooth Support Service

  1. Press Windows key + R, type services.msc and press Enter.
  2. Find Bluetooth Support Service, right-click it and choose Restart (choose Start if it is stopped).
  3. Double-click the service and set Startup type to Automatic, then click OK.
  4. Try pairing again. If it still fails, restart the PC and try once more.

5. Run the Bluetooth troubleshooter

Windows 11: Settings > System > Troubleshoot > Other troubleshooters. Windows 10: Settings > Update & Security > Troubleshoot > Additional troubleshooters

  1. Windows 11: Start > Settings > System > Troubleshoot > Other troubleshooters, then select Run next to Bluetooth (this opens the Get Help troubleshooter).
  2. Windows 10: Start > Settings > Update & Security > Troubleshoot > Additional troubleshooters > Bluetooth > Run the troubleshooter.
  3. Follow the prompts and apply any fixes it offers, then try pairing again.

6. Update, roll back or reinstall the Bluetooth driver

  1. Right-click Start and choose Device Manager, then expand Bluetooth.
  2. Click View > Show hidden devices. Right-click any greyed-out entry for the device you are trying to pair and choose Uninstall device.
  3. If the problem began after an update, right-click the Bluetooth adapter (for example Intel Wireless Bluetooth or Realtek Bluetooth Adapter), choose Properties > Driver > Roll Back Driver if available.
  4. Otherwise right-click the adapter and choose Update driver > Search automatically for drivers, or install the latest Bluetooth driver from your PC or adapter manufacturer's website.
  5. If that does not help, right-click the adapter, choose Uninstall device, then restart the PC so Windows reinstalls it.
  6. Pair the device again after the restart.

Still not fixed?

Test the Bluetooth device with a phone or another computer. If it fails there too, the device itself needs a factory reset or support from its manufacturer. If it pairs elsewhere but never with this PC, perform a clean boot (run msconfig, hide Microsoft services and disable the rest on the Services tab, then restart) to rule out conflicting software such as third-party audio or Bluetooth utilities. A cheap USB Bluetooth 5.x dongle plugged into a USB 2.0 port is a reliable workaround for a failing built-in adapter. For a laptop still under warranty, contact the PC maker's support, since the Bluetooth radio is often combined with the Wi-Fi card.

Questions people ask

Why does my device show up in the list but still fail to pair?

Windows saw the device advertising, but it stopped answering before pairing finished. Usually it left pairing mode or reconnected to your phone. Put it back in pairing mode and select it within a few seconds.

My device says Paired but won't connect. What should I do?

Remove the device in Bluetooth settings, turn Bluetooth off and on, then pair again from scratch. A stale pairing record is the most common reason a device stays Paired but not Connected.

How do I make my Bluetooth headphones discoverable?

On most models, turn them off, then hold the power or Bluetooth button for 5 to 7 seconds until the light flashes rapidly. The exact method varies by model, so check the manual if that doesn't work.

Does this error mean my PC's Bluetooth is broken?

Usually not. If the device appeared in the Add a device list, the adapter can see it. The fault is usually the pairing handshake, a driver, or the Bluetooth Support Service, not the hardware.

It started after a Windows update. How do I fix it?

Open Device Manager, expand Bluetooth, open the adapter's Properties and use Roll Back Driver on the Driver tab. You can also install the latest driver from your PC maker's website.
