Hello @TR4M0NT1N ,

Welcome to our community.

The EX511 devices and Deco M5 units are part of different mesh systems and cannot work together as a unified mesh network. This is likely causing the stability and speed issues you're experiencing.

For your setup with many gaming devices and IoT devices, I'd suggest using the Deco M5 system as your primary network. Position the three Deco M5 units strategically throughout your house for optimal coverage. You can create a separate guest network for your IoT devices to improve security and network performance.
