Hello, i have issues with my m4 setup. I have 6 m4 decos arranged like so:

Ips router

     Main Deco

          Switch

               Deco 1

               Switch

                    Deco 2

                    Deco 3

                    Deco 4

                         Deco 5

The house is long and the isp router is at one end and i cannot run cables for each deco so i have to daisy chain them like this using switches like this.

In the app, only 2 satelite decos show connected through ethernet. Not the same each time, if i reset one it switches to ethernet and another one switches to wireless. 

Is there a limitation for the m4 where only 2 can be connected via ethernet? Should i upgrade the main deco? Would that work.

There does not seem to be am issue with the cables and it used to work fine 2 updates ago.

Any ideeas?
