AP and 2 repeaters in one line

Hello all,

Not sure what this is but i need some help. I have 1 mANTBox 2 12s setup in AP mode and 2 basebox 2 as repeaters setup in 300 m.
AP1-------RP2--------RP1
What i am trying to do is to connect those 2 repeaters to AP. Few time i have successfully connected but most of the time 1 reapeter connects from other reapeter.
I have tried to add rule to Connect list with mac and unched box Connect. This did not help. Its still after i force disconnect still connects to other reapeter. Am i missign somehting ?

Add the MAC of the other Basebox in /interface wireless access-list with forward=no and authentication=no. Do this on both.

Its seems this did helped. Thank you! All the best!
