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:AnswerCheck the signal level from your home to the barn. The extender does require at least a moderate level to be able to function. 200ft might be a stretch.
