A:AnswerI think it'll work for you. I have my Modem and Router in one room at front of hallway to the bedrooms, I placed the Wi Fi extender in living room ( in center of house), and we use computers and iPad and TV in family room at far end of house ( completely opposite end of house from modem). The family room is separated by concrete block from rest of living area. Get good reception everywhere.
A:AnswerOne may connect to the main or the extender, depending on where one is located; the whole point of the extender is to extend the wifi coverage, so one may connect to the extender when out of coverage of the main
