how to fix bluetooth connectivity

Disconnect the JBL speaker from nearby phones or tablets, remove its existing Windows pairing, then place it in pairing mode and add it again.

1. Clear other connections and re-pair

Some JBL devices may remain associated with one device at a time. If the speaker automatically connects to another device, temporarily turn off Bluetooth on that device—or remove the JBL entry from its Bluetooth settings—before pairing with Windows.^1^

Then on the Windows 11 PC:

1. Charge the speaker and place it close to the PC.
2. Open Start → Settings → Bluetooth & devices → Devices.
3. Find the JBL speaker, select More options (⋯) → Remove device → Yes.
4. Turn the speaker off and back on.
5. Activate its pairing/discoverable mode using the procedure for the exact JBL model.
6. Return to Settings → Bluetooth & devices, select Add device → Bluetooth, and choose the JBL speaker.^2^

2. If the speaker does not appear

1. Open Settings → Bluetooth & devices → Devices.
2. Under Device settings, change Bluetooth devices discovery from Default to Advanced.
3. Put the JBL speaker back into pairing mode and select Add device → Bluetooth again.^3^

If an old JBL entry remains:

1. Right-click Start → Device Manager.
2. Select View → Show hidden devices.
3. Expand Bluetooth.
4. If the JBL device appears, right-click it and select Uninstall device.
5. Restart the PC and repeat the pairing process.^1^

3. Repair the PC’s Bluetooth driver

Because the speaker works with other devices, continue with the Windows Bluetooth adapter if re-pairing fails:

1. Open Device Manager → Bluetooth.
2. Right-click the Bluetooth adapter—not the JBL speaker.
3. Select Update driver → Search automatically for drivers.
4. If Windows finds nothing newer, download the Windows 11 Bluetooth driver for the exact PC or motherboard model from its manufacturer.
5. Install it and restart Windows.^3^

Also run Settings → System → Troubleshoot → Other troubleshooters → Bluetooth → Run.

If Bluetooth is present in Device Manager but remains unusable after installing the correct driver:

1. In Device Manager → Bluetooth, right-click the Bluetooth adapter.
2. Select Uninstall device → Uninstall.
3. Shut down the PC, wait several seconds, and turn it back on.
4. If Windows does not reinstall the adapter, open Device Manager and select Action → Scan for hardware changes.^3^

If it connects but produces no sound

Open Settings → System → Sound → Output and select the JBL speaker. Windows may pair a speaker without automatically selecting it as the active audio output.^4^
