Reasons why a Bluetooth device cannot pair with a Windows computer
Before we talk about the solutions to fix Bluetooth connection problems, it is necessary to know the reasons why a Bluetooth device refuses to pair with another device. Let’s see some reasons why a Bluetooth device cannot pair with a Windows computer.
Fix Bluetooth connection problems in Windows 11/10
Above, we have seen some common causes of Bluetooth connection issues. Now, let’s talk about how to fix Bluetooth connection problems in Windows 11/10 devices. You can try the following solutions if you are facing Bluetooth connection issues on your Windows 11/10 computer. Before you proceed, we suggest you restart your computer, as sometimes the problem occurs due to a minor glitch that can be resolved only by restarting the Windows device. Also, try turning off the Bluetooth of your computer and then turning it on again. Sometimes, toggling the Bluetooth of a computer fixes the Bluetooth connectivity issues. If this does not help, go through the following fixes. Below, we have explained all these fixes in detail.
1] Make sure that the Bluetooth of your PC is turned on
Check if you have turned on the Bluetooth of your computer. The button to turn on and off the Bluetooth is available in Windows 11/10 Settings.
2] Check if the Airplane mode is turned on
Turning on the Airplane mode will turn off all the wireless connections on your Windows device. Hence, it is a quick way to turn off all wireless connections in one go. Bluetooth is also a wireless connection. Therefore, turning on the Airplane mode will automatically turn off the Bluetooth. Check if you have turned on the Airplane mode by mistake. If yes, turn it off.
Some laptops have a dedicated function key to toggle the Airplane mode. If your laptop does not have this function key, you can turn it on and off via Windows 11/10 Settings and Quick Settings.
3] Check your Bluetooth device’s battery
Make sure that your Bluetooth device is completely charged. If your Bluetooth device has non-rechargeable batteries, replace them and then check if you can connect your device to your computer or not. Also, make sure that your Bluetooth device is within range, otherwise, your PC will not be able to detect it.
4] Check your Bluetooth device
Sometimes, the problem is associated with the Bluetooth device and not with the Windows computer. To confirm whether your Bluetooth device is working or not, connect it to another computer (if available). If another computer is not available, you can check the functionality of your Bluetooth device by connecting it to your friend’s computer. If the Bluetooth device is connecting with your friend’s computer but not with your computer, the problem might be with your Bluetooth drivers. We will talk about this later in this article. If your Bluetooth device is not connecting to another computer, contact your device manufacturer. If your device is under warranty, you can replace it (as per the manufacturer’s policies).
5] Restart your Bluetooth device
Another effective solution to resolve the Bluetooth connection problems is to restart the Bluetooth device. The steps for the same are as follows: Now, see if you can connect it to your computer. If not, try the other solutions.
6] Check for interference issues
As we have explained earlier in this article, one of the causes of the Bluetooth connection problems is interference. Interference occurs when any of the following conditions are satisfied:
When you have placed your Bluetooth device near the USB 3.0 port.When your computer is connected to another wireless connection that is using the same frequency as Bluetooth.
If your laptop has a USB 3.0 port, you may experience Bluetooth connection issues if you have placed your Bluetooth device near the USB 3.0 port. This usually happens if there is a USB device connected to the USB 3.0 port. This occurs because the USB 3.0 cables have a tendency to emit radio frequencies that can interfere with the Bluetooth devices. The solution to fix this issue is to place the Bluetooth device away from the USB 3.0 port. If your computer is connected to another wireless connection that is using the same frequency band as Bluetooth, you may experience connection issues with Bluetooth devices due to interference. Wi-Fi signals can operate on 2.4 GHz and 5 GHz. If your Wi-Fi signal is using 2.4 GHz, it may cause interference with the Bluetooth devices. To get rid of this problem, change the frequency of your Wi-Fi signal from 2.4 GHz to 5 GHz. Read: Bluetooth headphones show up as two devices in Windows 11/10.
7] Remove your Bluetooth device and add it again
One effective way to fix the Bluetooth connection issues is to remove the Bluetooth device from your computer and then add it again. If your Bluetooth device was connecting to your computer previously but now, you are facing connection issues with your Bluetooth device, the Bluetooth device is already added to your computer. In this case, removing the Bluetooth device from the computer and adding it again can fix the problem.
The steps for the same are written below: Your Bluetooth device should now connect to your computer.
8] Run the appropriate troubleshooter
Windows devices come with built-in troubleshooting tools. You can run the appropriate troubleshooter to fix the problem that you are facing. Because you are experiencing Bluetooth connection issues on your Windows device, running the Bluetooth troubleshooter and Hardware & Devices troubleshooter can help.
To run Bluetooth troubleshooter on Windows 11, open the Settings app and go to “System > Troubleshoot > Other troubleshooters.” Now, click on the Run button next to Bluetooth. On Windows 10, open Settings and go to “Update & security > Troubleshoot > Additional troubleshooters.” Select Bluetooth and click on the Run button.
9] Update and reinstall Bluetooth drivers
One possible cause of the problem is the outdated and corrupted Bluetooth drivers. A driver is a piece of software that tells an operating system which type of device is connected to it. When a driver malfunctions, you may experience several issues with the respective device. If you are still experiencing Bluetooth connection issues on your Windows device, you should update your Bluetooth device drivers. On Windows computers, you can update your Bluetooth device driver via Windows Optional Update feature (if an update for your Bluetooth device driver is available there). If this does not work, we suggest you uninstall the currently installed Bluetooth driver from your system. Then visit the official website of your Bluetooth device manufacturer. Download the latest version of your Bluetooth device driver and install it manually.
10] Rollback your Bluetooth driver or uninstall the latest Windows Update
If the issue has started occurring after a certain Windows Update, this means that your Bluetooth device driver has also been updated along with the Windows Update. In such a case, you can uninstall the latest driver version and go back to the previous driver version. To do so, follow the steps below:
Now, check if the issue persists. If yes, uninstall the latest Windows Update. Read: Bluetooth keyboard or mouse keeps going to Sleep

Check the status of the Bluetooth Support Service and start it if you find it stopped. The steps to restart Bluetooth Support Service are as follows:
12] Configure the Bluetooth Support Service
If restarting the Bluetooth Support Service does not fix your problem, configure it by following the steps given below and check if it helps.
13] Check the status of the Device Association Service
The Device Association Service enables pairing between a Windows device and a wireless device. If this service is not running, you may face connection issues with your wireless devices. Check its status in the Services app. The steps for the same are written below:
14] Perform a System Restore
If you have created a system restore point, you can restore your system and check if this fixes the problem. This method is useful if the System Restore Point was created when there were no Bluetooth connection issues.
15] Perform an In-place Upgrade
If none of the above methods fixed your problem or if the Bluetooth is missing or it is greyed out in Windows Settings, performing an in-place upgrade can fix the issue.
