I live in a 200 year old dairy barn with 5 levels, my office is in the hayloft. I had to drill thru 8 inch thick Locust Wood (sometimes called ironwood) post and bean construction and wired every level, making all the cables myself. Of course if you are talking a dorm or something where you can't use a drill than WiFi is the only option. I wouldn't use powerline; grab something from Dlink or Netgear...preferably same brand as router in case yu have to call tech support, thy can't blame the other guy
