Hi,

I have 5 Deco X50 on my network ,see image

I have put a RJ45 between the deco 3 --- 4 ---- 5  . The Deco 3 is at 15 meter of the main unit and the 5 a 50 metre of the main unit . I don't find the option to tell the the main deco and the 3 deco to connect  instead of the 5 which is much further has a weak signal while the 3 if I unplug the RJ45 cable has an average signal to the main deco
