If your Logitech MX Master mouse suddenly stops responding, lags, or refuses to connect to your Windows 11 PC, the issue is often caused by a corrupted or unstable Bluetooth pairing. This can happen after Windows updates, driver changes, or simply after extended uptime.
The good news? In most cases, the fix is simple: remove the existing Bluetooth connection and pair the mouse again from scratch.
This step-by-step guide shows you exactly how to safely unpair, reset, and reconnect your Logitech MX Master mouse on Windows 11 to restore a smooth and stable connection.
⚠️ This guide applies specifically to the Logitech MX Master series (MX Master, MX Master 2S, MX Master 3, MX Master 3S) on Windows 11. Other models or Windows versions may follow slightly different steps.
Step 1: Remove the Existing Bluetooth Connection
First, you need to delete the current Bluetooth pairing so Windows can start fresh.
- Press Windows + I to open Settings.
- Go to Bluetooth & devices.
- Locate your Logitech MX Master mouse in the device list.
- Click the three dots next to it.
- Select Remove device.
- Confirm when prompted.
This clears any stored connection errors.
Step 2: Power Off the Mouse
Turning the mouse off resets its internal Bluetooth state.
- Flip your mouse over.
- Slide the power switch on the bottom to the Off position.
Leave it off for a few seconds.
Step 3: Restart Your PC
Restarting Windows refreshes system services, clears Bluetooth cache, and reloads drivers.
- Click Start → Power → Restart.
- Wait for Windows 11 to fully reboot before continuing.
Step 4: Put the Mouse Into Pairing Mode
Now you’ll prepare the mouse so your PC can discover it.
1- Turn the mouse back On using the bottom switch.
2- Press the Easy-Switch button to select a connection slot (1, 2, or 3).
3- Press and hold the Easy-Switch button for about 3 seconds.
4- Release when the LED starts blinking rapidly.
The blinking light means the mouse is now in Bluetooth pairing mode.
Step 5: Pair the Mouse in Windows 11
With pairing mode active, reconnect the mouse:
1- Press Windows + I to open Settings.
2- Go to Bluetooth & devices.
3- Click Add device.
4- Choose Bluetooth.
5- Wait for the scan to complete.
6- Click your Logitech MX Master mouse when it appears.
7- Follow any on-screen instructions to finish pairing.
After a few seconds, the mouse should connect and become usable again.
Troubleshooting Tips
- Make sure Bluetooth is enabled on your PC.
- Keep the mouse close to your computer during pairing.
- If pairing fails, repeat the steps using a different Easy-Switch slot.
- Update your Bluetooth drivers and Windows version if issues persist.
