I use the devolo dlan 1200. I have a ground pin in every socket. I plug them directly into the wall. Also I don't live in an apartment.

Thanks for explaining! So there is nothing that I can do to make my powerlines faster? they went from 65 to 25 mbits because of adding more.

Does adding another powerline to the router help with the speed of the powerlines? Or will this just interfere with the original connection? I have a lot of powerlines recently but they all lost quite some speed because of that, so that's why I got this crazy idea. Thanks!
