OK .. maybe somebody can answer this.  I purchased an AC1750 (Archer A7) and an RE450 .. my hope was to build a mesh that would give me decent coverage . I have a modest 2 story home .. the A7 by iteself gets a signal to most of it .. all of it but very weak in some spots so figured the RE450 would make it a solid one network setup.

I have the 450 in .. used the RE button and WPS and all lights are lit.  In the WEB interface of the A7 I see the Archer and a Onemesh icon .. shows many devices on wireless but "0" next the Onemesh even tho the RE450 is in a room where 2 laptops are up and running as well as an echo device.  

Am I missing part of a setup or is this RE450 not a one mesh device? Why is nothing connecting to it?
