I have a problem,

my house having 3 floors, 

I setup the main node in the 1st floor.

bedroom in 2nd floor

my working room in 3rd floor

The problem is both 2nd, 3rd node in 2nd and 3rd floor is connecting to the main node in 1st floor, instead of 1 to 2 and 2 to 3.

So the signal from 1 to 3 is very weak, from 1 to 2 is good. With slow signal, my connection is weak too on the 3rd floor.

How to I can manually setup it can be connect 1 to 2 and 2 to 3 ?
