I'm in the UK and with BT ftth  

(940/110)  using ax72 v.0.1. 

I have a brick built 2 storey house with lots of thick solid internal walls, 

currently running 3x ax72's 

One main and 2 satellite in AP mode, 

The main unit has a pretty strong signal range on its own ive just added the other 2 for my top floor to have full wifi speeds  as 4 brick walls later it does take a hit in wifi performance underatandably and one down the bottom of my garden in my mancave,

needless to say i have complete coverage at full speeds at my whole property and further past my property line. 

It's very rare that I get any lower than 850 down even at peak times and with my kids on multiple devices at the same time streaming and playing games online.  

My ax72's have been pretty solid for me so I'd reccomend it.
