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?
I'm in an apartment, it's a 1br but I've got about 10 breaker switches in my utility closet. I've got these things on separate breakers on opposite sides of the main room and it still works. It's a gamble worth taking, just buy from a seller that will allow return, easy enough to explain if it doesn't work with your wiring. I thought the same thing but decided to give it a shot, glad I did, thing works like magic!
