Hi,

I have a Deco M9 with 3 units. My main unit is connected to my internet access point. The extra ethernet port on the main unit is connected to a switch. My 2 slave units are directly connected to this switch as well so all 3 deco's are connected to eachother via wire. 

As of lately (2 months or so), my slaves become "unavailable" from time to time, it says that they are "disconnected" from the main deco and they both have a flashing red light. How can they be disconnected if they are connected through ethernet? Is there something wrong in my settings? Somtimes they loose their connection at the same time, other times it's just a single unit loosing connection. They do recover themselves most of the time (sometimes i need to disconnect the power and reconnect again).

Unfortunatlely there are no logs I can find in the app to get more info. Anyone else experiencing this?
