Hello Guys and Girls,

for context, my gf and i bought a deco m4 3 pack to combat the poor w-lan covarage at home. The home has 2 floors and realy thick walls... The initial router is standing at the top floor 2 at the outer wall. The Problem is that we cant move the router to a different location. So we are stuck with the Main-Deco on the Topfloor at the outer wall. 

So as u can guess the floor below has poor coverage (it drops from 400 mb/s to 80 mb/s .............). So we have the Main-Deco upstairs, a second Deco satellite right below at floor 1(only dropping to 250 mb/s now) and we have one, the third one, at the other side of the floor 1.

The Problem is now that the third Deco only connects to the Main-Deco upstairs. As i said already, we can't move the main deco. Is there a possebility that i can connect the third Deco satellite to the second Deco satellite for a better covarage and speeeeeeed? If so, how does it work? And can i do this without an ethernet cable?

Thanks for ur help and sorry for my poor english.

Kind regards
