How to Fix a Bluetooth Device That Won't Pair

Quick answer

When Bluetooth won’t pair, the device is usually not in pairing mode, is still connected to another phone or computer, or is low on battery. Charge it, put it into pairing mode, keep it close to your computer, then remove any old entry for it and pair again. This guide is for Windows 11 and Mac users trying to connect headphones, speakers, mice, keyboards, game controllers and similar devices.

Before you start

Picture a pair of wireless earbuds that connect to your phone every morning but refuse to show up on your laptop. Most of the time, the earbuds are simply grabbing the phone first. Run through these checks:

• Charge the device. Low batteries cause weak, unreliable pairing.
• Turn Bluetooth off on nearby devices. If the device was used with a phone or tablet, turn Bluetooth off on that phone for a moment so it can’t reconnect first.
• Move closer. Keep the device within a few feet of the computer, with nothing metal in between.
• Restart both. Turn the device off and on, and restart the computer.
• Check that Bluetooth is on. On Windows 11, open quick settings from the network or volume icon on the taskbar. On a Mac, use Control Center or System Settings, then Bluetooth.

A note on safety: only accept pairing requests from devices you own and are expecting. If a pairing code appears, it should match on both screens; you don’t need to share it with anyone. Real tech companies won’t call you to “fix” Bluetooth or ask for remote access to your computer.

Put the device in pairing mode and pair again

Pairing mode (also called discoverable mode) is a short period when a device announces itself so a computer can find it. How you start it differs by device: often you press and hold the power button or a Bluetooth button until a light flashes, but some earbuds use the charging case button and some keyboards use a key combination. Check the device’s manual or the maker’s support site for the exact steps.

Windows 11

1. Open Settings, then Bluetooth & devices.
2. If the device is already listed but won’t connect, select the three dots (or the device itself) and choose Remove device. Confirm.
3. Put the device into pairing mode.
4. Select Add device, then Bluetooth.
5. Choose your device when it appears. If a code shows, confirm it matches the one on the device, or type the code shown if asked.
6. Wait for the message that the device is ready to use.

If the device doesn’t appear, look on the Devices page under Bluetooth & devices for a setting called Bluetooth devices discovery. In some versions of Windows 11, setting it to Advanced shows more types of devices. In Windows 10, the same steps are under Settings, then Devices, then Bluetooth & other devices.

macOS

1. Open System Settings and click Bluetooth.
2. If the device is already listed, click the Info button next to it (or Control-click its name) and choose Forget This Device, or Remove in some versions. Confirm.
3. Put the device into pairing mode.
4. Wait for it to appear under nearby devices, then click Connect.
5. If a code appears, confirm it matches or type it on the device as asked.

Some Apple accessories pair automatically when you bring them near a Mac signed in to the same Apple Account. Others work like any other Bluetooth device.

Fix the computer’s Bluetooth

If several devices won’t pair, or the Bluetooth switch is missing, the computer’s Bluetooth needs attention.

Windows 11

1. Run the Bluetooth troubleshooter: Settings, then System, then Troubleshoot, then Other troubleshooters. In some recent versions, Windows sends you to the Get Help app for this.
2. Install updates from Settings, then Windows Update, including any driver updates listed under Advanced options, then Optional updates. A driver is the small program that lets Windows use the Bluetooth hardware.
3. Open Device Manager (right-click the Start button) and expand Bluetooth. If you see a warning triangle, right-click the adapter and choose Update driver. You can also download the Bluetooth driver for your exact model from your computer maker’s official support site.
4. If your desktop PC uses a plug-in USB Bluetooth adapter, see how to fix a USB device that isn’t recognized.

macOS

1. Turn Bluetooth off and back on in System Settings, then Bluetooth.
2. Restart the Mac.
3. Install macOS updates from System Settings, then General, then Software Update.
4. Remove the device again, then pair it fresh.

If this does not work

Try these next steps, easiest first:

• Reset the device. Many headphones, speakers and keyboards have a reset method that clears old pairings. The steps vary by model, so follow the maker’s instructions exactly.
• Reduce interference. Bluetooth shares the 2.4 GHz radio band with many Wi-Fi networks, microwaves and USB 3 hubs. Move away from those and test again. Our guide to slow Wi-Fi explains the 2.4 GHz band in more detail.
• Test with another computer or phone. If the device won’t pair with anything, the device itself may be faulty.
• Check compatibility. Some devices need a companion app or a specific Bluetooth version. The maker’s support site will say what is supported.
• Try a cable. Many keyboards, mice and headphones also work with a USB cable, which can keep you working while you sort out Bluetooth.

When to get professional help

Contact the device maker, your computer maker, or a qualified technician if:

• No Bluetooth devices pair, and Bluetooth is missing from Settings and Device Manager, even after updates.
• The device won’t pair with any computer or phone after a reset.
• A battery-powered device swells, leaks, gets hot or smells of burning. Stop using and charging it, and have the battery handled professionally.
• The device is under warranty. The maker’s support can arrange the right repair or replacement through its official channels.

FAQ

Why won’t my headphones show up on my laptop?

They are probably not in pairing mode or are already connected to your phone. Turn Bluetooth off on the phone, put the headphones in pairing mode, and search again. Removing any old entry for them on the laptop first also helps.

What does “Try connecting your device again” mean in Windows?

Windows started pairing but didn’t finish, often because the device left pairing mode or the code wasn’t confirmed in time. Remove the device, put it back into pairing mode, and pair again while keeping it close.

Do I need to install a driver for Bluetooth headphones?

Usually not. Windows and macOS include support for common devices like headphones, mice and keyboards. Your computer’s Bluetooth adapter does need a working driver, which comes through Windows Update or your computer maker’s official site.

Is it safe to accept a Bluetooth pairing request?

Only if you started the pairing yourself and recognize the device name. Decline requests you weren’t expecting, especially in public places. Pairing codes are for matching on screen, not for sharing with anyone.

Why does my Bluetooth device keep disconnecting?

Distance, low battery and interference are the most common causes. Keep the device close, charge it, and move away from busy Wi-Fi equipment and microwaves. Updating the computer’s Bluetooth driver can also improve stability.
