Whole Home Wifi questions - best hardware?

[PandaBear]

I want to set it up and be done, not go back and re-position a router. I've done a lot of wireless setups and with a large homes a single router always leaves some area (often the driveway, basement, etc.) with subpar or nonexistant service, even if you have it located in an ideal spot. Again, cost not a concern here, so while he might get away with a low cost solution, it makes no sense to pinch pennies.

Indoor wireless is like a light going through a bunch of tinted windows. You can get the most expensive most powerful light source (router) and it will still be hard for it to shine through multiple layers of tint (walls). It is far easier to have multiple light sources and not trying to stretch physics.

IMO 2-4 APs (including the router) and powerline ethernet are the most bullet proof way to set this up. Even cheap APs 1 or 2 generation older spread out would still beat it a single high end router.
