Wifi works pretty good throughout our house except out in our family room which was an addition onto the house. Long time ago I ran an ethernet line out there and put a switch in the room for devices that needed it. We recently got a firestick for the tv and the wifi signal isn't that good. I was thinking about getting a wifi extender but don't know anything about them. My question is should I get one that plugs into a wall outlet? I've seen some that look like they use ethernet as well. Not sure and just wanted your opinions about this.
