Bluetooth Not Working on Windows? How to Fix It
Bluetooth lets you connect wireless headphones, speakers, mice and keyboards to your PC. When it stops working, the Bluetooth toggle might disappear, devices might refuse to pair, or audio might cut out. Here's how to fix it.
Make sure Bluetooth is on
- Press Windows + A to open Quick Settings and check the Bluetooth tile is on.
- Check that Airplane mode is off.
- Some laptops have a keyboard shortcut or physical switch for wireless; check the function keys.
Pair the device properly
- Put the device in pairing mode. This usually means holding its power or Bluetooth button until a light flashes. Check its manual.
- Go to Settings → Bluetooth & devices → Add device → Bluetooth.
- Select the device when it appears.
If the device was paired before and now fails, click it in the device list and choose Remove device, then pair again. Also make sure it isn't currently connected to your phone, since many headphones connect to only one device at a time.
Bluetooth option is missing
- Right-click Start and open Device Manager.
- Expand Bluetooth. If you see a yellow warning icon, right-click the adapter and choose Update driver.
- If Bluetooth isn't listed, click View → Show hidden devices, or click Action → Scan for hardware changes.
- Download the latest Bluetooth driver from your laptop or motherboard manufacturer's website.
Desktop PCs often don't have Bluetooth built in. A small, inexpensive USB Bluetooth adapter adds it.
Restart the Bluetooth service
Press Windows + R, type services.msc, and find Bluetooth Support Service. Right-click → Restart, and set Startup type to Automatic.
Use the troubleshooter
Go to Settings → System → Troubleshoot → Other troubleshooters → Bluetooth.
Audio cuts out or sounds bad
- Keep the device close to the PC and away from Wi-Fi routers and microwaves.
- Turn off power saving for the adapter: in Device Manager, open the Bluetooth adapter's properties → Power Management → untick Allow the computer to turn off this device.
- If audio sounds like a phone call when you join a meeting, that's normal: Bluetooth switches to a lower-quality mode when the headset microphone is used. Use your PC's microphone instead to keep high-quality audio.
For other sound issues, see no sound on Windows.
Tips for specific Bluetooth devices
Wireless earbuds and headphones
Many earbuds remember several devices and automatically reconnect to the last one used, often your phone. Before connecting to your PC, disconnect them from your phone or turn off the phone's Bluetooth. Some brands have a companion app that lets you manage multiple connections. If audio sounds low quality during calls, choose the PC's own microphone in meeting app settings so the headset stays in high-quality stereo mode.
Bluetooth mice and keyboards
- Replace or charge batteries first; low power causes lag and disconnections.
- Some mice come with a small USB receiver; that often works more reliably than Bluetooth.
- Avoid plugging USB 3.0 devices right next to the Bluetooth adapter, which can cause interference.
Speakers
For the best range, keep a clear line of sight between the PC and speaker, and stay within about 10 metres. Walls, especially concrete, reduce range significantly.
Game controllers
Xbox controllers pair with Windows over Bluetooth on newer models; hold the pairing button until the logo flashes quickly. Some controllers need a firmware update through the Xbox Accessories app to connect reliably.
Use Swift Pair
Windows 11 supports Swift Pair for compatible devices. Turn on Show notifications to connect using Swift Pair in Bluetooth & devices → Devices. When a compatible device is in pairing mode nearby, a notification pops up and you can connect with one click.
Security note
Turn Bluetooth off when using public places if you don't need it, and never accept pairing requests from unknown devices.
Frequently asked questions
How many Bluetooth devices can connect at once?
Usually several, such as a mouse, keyboard and headphones together, though performance can drop with many active devices.
Why does my Bluetooth mouse lag?
Low battery, interference or USB 3.0 ports near the adapter can cause lag. Replace batteries and move the device closer.
