I have a relative whos router is installed in her garage and her hopper is on the other end of the house. As you can imagine the Wi-Fi signal to it maxes out at 5. There is a joey on the other side of the wall from the router would i be able to just plug a cat 5 into it? Or would my best bet be to run cat 5 acrossed her house? I don't have this problem at my own home as I already have cat 5 ran to my living room and hopper.
