I'm in a multi-level home. Previously I had 1 centrally located Ruckus AP. Its signal was strong everywhere (solid RX signal strength), but devices could not transmit strongly enough back to the AP. In the end I went with 3 Unifi APs + a controller. You can use wired or wireless for backhaul. The main thing is that the APs have to be able to communicate with each other. There isn't a great way to test out the wireless backhaul without buying the equipment. I suppose you could use a scanner to test the RX signal strength with your AP in varying places. If the 2.4/5ghz signal is strong in the (AP, scanner location) pairs then you know the APs might be able to talk to each other. If you're looking for a less work setup, the Amplifi line, or Eeros might work.
