Hi Everyone 

I have bought 6 times DECO M9PLUS. 

I have the idea it's not working optimal. 

May'be it's me not installing it the right way. 

We have an internet connection 300Mbps down and 30upload and it's according to ookla also that speed. 

I have a head deco that is trough ethernet cable connected to my modem. 

15m away in the same room I have another DECO that is connected to a netgear.gs105 switch. 

The switch is connected directly to the modem and the DECO is than connected to the switch. 

15 meter away I have another DECO that is just powered by electricity. 

on the first floor I have another 2 DECO's in separate rooms. 

Is there something not right in my setup? 

I would like to have a DECO in my garden 30 meters away from my home. 

Best is to do this trough ethernet cable? 

May'be someone can advise me :-) 

Thanks 

Sébastien
