When Bluetooth is not working in Windows 11, it usually shows up in one of a few annoying ways. Your headphones keep disconnecting at random. Your mouse says “Paired” but won’t connect. Or your PC simply can’t find a device it found yesterday. Restarting helps for a few minutes, and then the problem comes right back.
Most of these problems come from Windows itself, not your device. A power-saving setting turns off your Bluetooth chip, a background service crashes, or a Windows Update swaps in the wrong driver. The 7 fixes below start with quick settings and move up to Device Manager and service fixes, so try them in order.
Is the Bluetooth Toggle Missing Completely?
Check this first, because it changes which guide you need.
- You can see the Bluetooth switch in Settings or Quick Settings, but connections fail or drop: you’re in the right place. Keep reading.
- The Bluetooth switch, tile, or icon is gone completely: Windows can’t see your Bluetooth adapter at all. That needs a different set of fixes, starting with a full power drain. See how to fix Bluetooth missing from Windows 11.
1. Check Airplane Mode and the Bluetooth Toggle
Fixes: Bluetooth that seems “on” but does nothing.
It sounds too simple, but it catches a lot of people. Airplane mode turns off Bluetooth, and turning Airplane mode back off doesn’t always turn Bluetooth back on.
- Press Windows + A to open Quick Settings.
- Make sure Airplane mode is off (grey).
- Make sure the Bluetooth tile is on (blue).
- Turn the Bluetooth tile off, wait 10 seconds, then turn it back on. This quick reset often wakes a stuck connection.

2. Change Discovery to “Advanced” in Windows 11 Settings
Fixes: your PC can’t find a certain device, like an older game controller, speaker, or keyboard.
Some versions of Windows 11 only show common devices in the Add device list to keep it tidy. Older or unusual devices can be left out, so it looks like your PC “can’t see” them.
- Go to Settings, then Bluetooth & devices, then Devices.
- Scroll to Bluetooth devices discovery.
- Change it from Default to Advanced.
- Click Add device, then Bluetooth, and search again.
If you don’t see this setting, your version of Windows 11 already shows all devices, and you can skip this fix.
See every Windows Bluetooth setting explained.
3. Clear the Connection: Remove and Re-Pair
Fixes: a device that says “Paired” but won’t say “Connected,” or one that used to work and suddenly won’t.
“Paired” only means your PC remembers the device. “Connected” means they’re actually talking right now. When the saved pairing data gets corrupted, the two can stay stuck at “Paired.” Removing the device clears that bad data.
- Go to Settings, then Bluetooth & devices, then Devices.
- Find your device, click the three dots, and choose Remove device, then Yes.
- Restart your PC.
- Put your device in pairing mode (usually a flashing light).
- Go back to Bluetooth & devices, click Add device, then Bluetooth, and pick your device.
If your headphones or speaker still refuse, they may be holding an old pairing on their side too. Resetting the accessory clears it.

4. Run the Built-In Bluetooth Troubleshooter
Fixes: basic setting and service problems, automatically.
Windows has a free tool that checks common Bluetooth problems and fixes some by itself. It won’t solve everything, but it’s quick and safe.
- Go to Settings, then System, then Troubleshoot.
- Click Other troubleshooters.
- Find Bluetooth and click Run.
On newer versions of Windows 11, this opens the Get Help app. Follow its prompts. If it says it found and fixed a problem, test your device again. If not, move on.
5. Stop Windows from Turning Off Your Bluetooth
Fixes: Bluetooth that disconnects randomly, especially on laptops or after your PC sleeps.
This is the most overlooked fix. To save battery, Windows is allowed to switch off your Bluetooth chip when it thinks you’re not using it. Sometimes it doesn’t wake it up properly, so your headphones or mouse drop out for no clear reason.
- Press Windows + X and choose Device Manager.
- Expand Bluetooth.
- Right-click your Bluetooth adapter (it usually has Intel, Realtek, MediaTek, or Qualcomm in its name) and choose Properties.
- Click the Power Management tab.
- Untick Allow the computer to turn off this device to save power.
- Click OK and restart your PC.
Don’t see a Power Management tab? Not every adapter has one. On many laptops, the Bluetooth chip connects through USB inside the PC, so you can also do the same thing for each USB Root Hub under Universal Serial Bus controllers.
Your battery may drain a tiny bit faster, but your connections should stay steady.
See why Windows Bluetooth keeps turning off by itself.
6. Restart the Bluetooth Support Service (bthserv)
Fixes: Bluetooth that stops finding or connecting to anything, even though the switch is on.
Windows runs a background program called the Bluetooth Support Service (bthserv). It handles finding and connecting devices. If it crashes or stops, Bluetooth looks normal but nothing works.
- Press Windows + R, type services.msc, and press Enter.
- Find Bluetooth Support Service.
- Right-click it and choose Restart. If Restart is greyed out, choose Start.
- Double-click it and set Startup type to Automatic. Click OK.
While you’re there, restart Bluetooth Audio Gateway Service and Bluetooth User Support Service too, if you see them. They help with headphones and calls. Then restart your PC.
See a full guide to the Bluetooth Support Service.
7. Fix Driver Conflicts Caused by Windows Update
Fixes: Bluetooth that broke right after a Windows update, or keeps failing no matter what.
Windows Update sometimes replaces your PC maker’s Bluetooth driver with a basic Microsoft one. In Device Manager, it may show up as Generic Bluetooth Radio or Generic Bluetooth Adapter. That driver works for simple connections but can cause drops, bad audio, or missing features.
And if you try Update driver, Windows often says “The best drivers for your device are already installed.” That only means it checked the drivers already on your PC, not the newest official version.
If Bluetooth broke after an update, roll the driver back:
- Open Device Manager and expand Bluetooth.
- Right-click your adapter and choose Properties.
- On the Driver tab, click Roll Back Driver.
- Pick a reason, click Yes, and restart.
If Roll Back is greyed out, get the official driver from your PC maker’s support site (Dell, HP, Lenovo, ASUS, and so on) or the chip maker, then do a clean reinstall.
See how to update, reinstall, or roll back your Bluetooth driver.
See deeper fixes when a Windows update breaks Bluetooth.
Avoid third-party “driver updater” apps. They often install the wrong driver.
Still Not Working? It Might Be the Device
If every fix above failed, test your accessory with another phone or PC. If it fails there too, the problem is the device, not Windows.
See how to tell if it’s the device, the OS, or the adapter.
Frequently Asked Questions
Why does my Bluetooth keep disconnecting randomly on Windows 11?
Most often, Windows is turning off the Bluetooth chip to save power. Untick “Allow the computer to turn off this device to save power” in Device Manager (Fix 5). A bad driver from Windows Update is the next most common cause.
How do I restart the Bluetooth service in Windows 11?
Press Windows + R, type services.msc, find Bluetooth Support Service, right-click it, and choose Restart. Set its Startup type to Automatic.
Why does Windows say my Bluetooth device is paired but not connected?
The saved pairing data is often corrupted. Remove the device in Settings, restart, put it in pairing mode, and pair it again.
Why does Device Manager say my Bluetooth driver is already the best one?
“Search automatically” mainly checks drivers already on your PC. Check Optional updates in Windows Update or your PC maker’s site for the newest official driver.
Can USB 3.0 devices make Bluetooth worse?
Yes. USB 3.0 ports and hubs can give off interference in the same 2.4GHz band Bluetooth uses. If problems start when a USB 3.0 drive or hub is plugged in, move it away or use a different port. See how USB 3.0 ports interfere with Bluetooth.
