Powerline ethernet is a standard for running data over your in-wall electrical wiring. Earlier versions hardware was flakey, but now I got months and months without ever having to restart these TP-Link adaptors. You simply plug them into a wall socket and voila, ethernet port.
There isn't much configuration to do, unless you intend to have more than 2 ports in your home. Even then it is all very, very simple.
For getting the most difficult dead spots live on the internet forget wireless and try Powerline.
