In most countries all routers have the same maximum power so you see little variation on distance and wall penetration. You may encounter folk that think one router rules them all but unless you go rogue and get some illegal high power router that you can't buy at a store, the answer is this is not how this is solved.
I use powerline networking if walls stand in the way.
