I recently purchased a AX21 and 2 RE600Xs to use in the one mesh system.

Question does one mesh work like a true mesh system where all the units communicate with each other or do the extender nodes (RE600X) only communicate back to the main router and not also between themselves?

I have my main router on one side of my house, a node in the middle, and another on the opposite far side. This far side node seems to have communication issues and occasionally shows up as weak connection which is makeing me wonder if its not communicating with the middle node.

Can anyone clairify? I used first gen google wifi tri-pack before this and all seemed to work fine
