My Eero 6+ disconnects if there is no commnication

Hi,

I have 6+ mesh network. I have two switches with one eero LAN connection. Eero disconnects the devices if there is no communication to the devices on the network. I do not know how to keep them "alive" on the network. Some of my NAS drives getting disconnected because of this issue. How to keep them "alive" on the network?
