We have a multi-story townhome and tried powerline. When it worked it was very good; "when", unfortunately, was not nearly as often as we needed it to be.

We recently just got a Netgear Orbi and are pretty well satisfied. Turns out the base router/AP is better overall than the other single unit devices we've been using until now and the satellite does seem to make a significant difference in the far top floor room which had problems with both WiFi & Powerline. Lucky for that, too.... our next step was to run cable in the walls.
