Windows 11 Bluetooth Not Working? Fixes That Actually Help

Windows 11 Bluetooth not working can mean several different things: the Bluetooth switch has vanished, a device will not pair, or headphones connect but keep dropping out. The fixes overlap, so this guide runs from the quickest checks to the deeper driver and service fixes. Test your device after each step.

Everything here applies to Windows 11 version 24H2 and 25H2 on both Home and Pro.

Quick checks before you dig in

Many Bluetooth problems have nothing to do with Windows.

• Charge the accessory. Low batteries cause pairing failures and dropouts long before the device dies.
• Turn the accessory off and on, and keep it within a few metres of the PC with no walls in between.
• Check it is not connected elsewhere. Earbuds often reconnect to a phone first. Turn off Bluetooth on the phone while you test.
• Move away from interference. Microsoft notes that unshielded USB 3.0 devices and cables can interfere with Bluetooth. Wi-Fi routers and microwaves can too.
• Confirm your PC has Bluetooth. Most laptops do, but many desktops need a USB Bluetooth adapter.

Check the toggle and Airplane mode

Open Settings > Bluetooth & devices. The Bluetooth switch at the top should be on. You can also select the network, sound or battery icons on the taskbar to open Quick Settings and check the Bluetooth tile there.

While in Quick Settings, make sure Airplane mode is off, because it turns off Bluetooth along with Wi-Fi. Some laptops also have a hardware wireless switch or function key.

Then try the simplest fix: switch Bluetooth off, wait a few seconds and switch it back on. For more about these controls, see our Bluetooth settings guide.

Run the Bluetooth troubleshooter

Windows 11 has an automated Bluetooth troubleshooter. Go to Settings > System > Troubleshoot > Other troubleshooters and select Run next to Bluetooth, or open it from the Get Help app. It checks the adapter, the service and common settings, and applies fixes it finds.

Remove the device and pair it again

If one device misbehaves while others work, its pairing record may be corrupted. Removing it and pairing from scratch clears that out.

1. Go to Settings > Bluetooth & devices > Devices.
2. Find the device, select the three-dot More options menu and choose Remove device, then Yes.
3. Put the accessory into pairing mode. This is often a long press on the power or a dedicated pairing button; check its manual.
4. Back in Settings > Bluetooth & devices, select Add device > Bluetooth and choose it from the list.

If the device does not show up in the list, go to Bluetooth & devices > Devices > Device settings and set Bluetooth devices discovery to Advanced, which shows all device types.

Restart the Bluetooth Support Service

Windows uses the Bluetooth Support Service to discover and pair remote devices. If it is stopped or stuck, devices will not connect even though the toggle looks fine.

1. Search for Services and open it.
2. Scroll to Bluetooth Support Service.
3. Right-click it and choose Restart (or Start if it is not running).
4. Double-click it and check Startup type. If it says Disabled, change it to Manual, select Apply, then start the service.

You do not normally need to set it to Automatic; Windows starts it when Bluetooth needs it. If you see a separate Bluetooth Audio Gateway Service or a service from your Bluetooth chip maker, restart those as well when troubleshooting headsets.

Update or reinstall the Bluetooth driver

A missing toggle, a yellow warning icon in Device Manager, or problems that began after an update point to the driver.

1. Right-click Start and choose Device Manager.
2. Expand Bluetooth. The adapter is often named after the chip maker, such as Intel or Realtek, and may include the word “radio”.
3. Right-click it and choose Update driver > Search automatically for drivers.
4. If Windows finds nothing, download the latest Bluetooth driver for your exact model from the PC maker’s support site and install it.
5. If the problem persists, right-click the adapter and choose Uninstall device, then shut down from Start > Power, wait a few seconds and power on. Windows reinstalls the driver. If it does not, choose Action > Scan for hardware changes in Device Manager.

If the problem started right after a driver update, open the adapter’s Properties, go to the Driver tab and use Roll Back Driver. If there is no Bluetooth category at all, check Other devices or Unknown devices, and on a desktop try the USB adapter in a different port.

Audio-specific Bluetooth problems

Headphones that connect but give no sound, or sound that is poor quality during calls, are usually an output-device issue rather than a Bluetooth fault. Open Settings > System > Sound and make sure the headphones are selected under Output. Headsets often appear twice, once as a high-quality stereo device and once as a hands-free device used for calls. Our audio not working guide covers output devices in detail.

When nothing works

Check for pending updates in Settings > Windows Update, since Bluetooth fixes often arrive through driver and cumulative updates. Test the accessory with another device to rule out a hardware fault. If the problem appeared alongside other driver and system issues, running System File Checker can repair damaged system files. For other problems, see the Windows 11 troubleshooting hub.
