Not sure who you are asking, but I was using a bridged WiFi connection on a laptop and the network got too congested, or it basically started acting shitty... Anyways, I got a TPLink powerline kit for like $40, router to wall on one end, wall to switch on the other; works awesome, cheap, steady, good speed, and I don't need to mess with any long wires.
I thought of getting one of these to ease the job as well but arent they suppose to run on the same circuit?
