I live in a 2 bedroom apartment with the bedrooms on opposite ends of the apartment. I currently have 4th generation AEBS in my bedroom (so that I can run ethernet to my devices and so that the wifi extends into the backyard.) However, my roommate is complaining that he gets very poor wifi reception in his bedroom as well as the livingroom (I have confirmed that it is pretty slow.) I have been considering purchasing a new router (TP-Link Archer C7- as per wirecutter.com's recommendation) and using it as an access point in my room while moving the older AEBS into the other side of the apartment and setting it up as the main router. Is it a bad idea to have an older router (wireless N) as my main router and a newer router (wireless AC) as an access point?
