Three storey house WiFi

[slenderman379]

Recently moved into a new house, and this place needs a beefy WiFi setup. 

 

The house is 3 floors high, and made of concrete, including the walls. I wanna have 3 routers, 1 for every floor so that I can have good speeds and connectivity throughout. But I also don't wanna have to switch connections when I go from one floor to another, so I want them to be the same id and pass, kinda like how schools do it.. I don't have much expertise in this, but I think I'm adept enough to follow instructions. 

 

I mentioned the concrete because I will need a set up with good range to work thru these thick walls.

Budget wise I'm thinking ~600$ ish for the whole thing. 

 

Also, I already have lan cables on every floor run through the walls, so I don't have to worry about that at least

Don't get three routers, get one router and two or three access points. 

 

I'd recommend picking up three Ubiquiti UniFi AP AC Pro access points, putting one on each floor and just turning the WiFi on the router off. Set the UniFi APs to work together for zero-handoff and you've got fast, seemless roaming. Connecting them all up to a 802.3af/at compatible switch may be desirable too as it removes the need for the somewhat bulky PoE injectors.
