I have 3 orbi 2 are Rbs20 and 1 an rbw30 .2 orbi(which are the rbw and one of the rbs)connect to the rbs which it is 20/25 metres away and a wall from the rbw and 40 metres and a wall away from the rbs. They alaways connect very well but i have a problem with my ps4 because while i'm playing i crash from the match and the party and after 15 seconds it riconnects by himself on the orbi.(my ps4 is on a limbo zone because is one floor away from the rbw and 5/6 metres away from the rbs)
