Users who attempt to pair using Bluetooth sometimes complain about connection and pairing problems.

Some users can’t find the MX Master 3 Bluetooth in their PCs’ available Bluetooth connections. While others report that nothing happens if they try to pair the mouse with the PC. This problem is very annoying and overshadows all other amazing features and specifications.

If you are also facing these problems, we suggest trying the solutions in this post before giving up on this fantastic device.


Reconnect Your Mouse

Disconnecting and reconnecting your mouse is usually the first solution when your electronic devices stop working. Try disconnecting, reconnecting, and then pairing your Bluetooth again. It resolves the issue mostly.

Update the Mouse Drivers

Logitech keeps updating the drivers for its devices. Ensure you have the latest updated MX Master 3 mouse drivers installed on your PC.

Update the Operating System

Please note that the Logitech MX Master 3 doesn’t support older operating systems. For example, it supports Windows 8 or later and Mac OS 10.10 or later. We recommend updating your OS if your PC is running one older than the ones mentioned here.

Check the Bluetooth version

Logitech MX Master 3 is not compatible with the Bluetooth 3.0 radio chips and technology. It supports a newer Bluetooth 4.0, which is also called Low Energy (LE) Bluetooth technology. If your OS doesn’t support this technology, you can connect the mouse through the proprietary dongle but not through Bluetooth. You can check here to see if your OS is compatible with Bluetooth LE 4.0.

Check nearby Wi-Fi Devices

Bluetooth 4.0 operates on 2.4 GHz, and so do most Wi-Fi devices. Sometimes if a Wi-Fi device is present in the vicinity, the interference between the Wi-Fi and Bluetooth is so strong that the signal can’t reach its destination. In that case, you can remove the Wi-Fi device from the surrounding area. Another option is to switch the Wi-Fi signal from 2.4 GHz to 5 GHz only if your router supports it.
