Universal Control disconnects randomly between MacBooks

Hi everyone,

here my current setup

• Apple Magic Keyboard
• Logitech Bluetooth Mouse MX 3S connected "directly" via Bluetooth
• MacBook Pro M4 (nov 2024 w/ macOS 26.0.1) with LG external monitor
• MacBook Pro M1 (2021 w/ macOS 15.6.1) sometimes with an iPad as second monitor

When I try to share Mouse and Keyboard between MacBooks everything works but only for few minutes.

For ex. suddenly stops working during type text.

This happened also before upgrading MacBook Pro M4 to new macOS.

Consider also that there is only 1 meter between MacBooks and WI-FI router is in the floor above.

Can you provide some hint in how to fix this problems.

In the meantime I'll try to update M1 MacBook to new macOS as well, but got feelings that does not solve the problem.

Thank you!
