A:Answer see my review of the Orbi. I was using the Apple AirPort Extreme system and it failed to work in my house (6000+ sq ft). From what I have read, the Orbi works better because the unit(s) outside the main router unit creates a web wifi that replicates the signal instead of retransmitting it (as the airport units do), meaning the signal from each satellite is as strong as its incoming signal. I thought adding more airport express units would extend the signal further from the main router; however, each airport express unit actually ended up only sending out half of the incoming signal.
However, if you want to try going the AirPort Extreme route - I haver a few airport express units I could sell to you...
