Hello all, I am going to be setting up WIFI in a new townhome soon, the unit has 3 stories and I am wondering how I can get good speeds on all 3 levels for under $500. Since I’m also in need of a new router anyway I might be able to spend a little more but I’d want to keep it relatively cheap but not that cheap because I want good quality.

Please explain it like you are talking to a senile old man, thank you
