They basically turn all the electrical wires in your house into a giant antenna and radiate broadband noise.
I honestly don't know how the damn things are even legal by the FCC given how noisy they are.

And they do it very poorly, I've never been able to get powerline networking to work well. I had trouble reaching the Wifi node in my office from the bedroom on the far side of the house, I thought powerline networking was the answer, but the link was not that fast (around 10mbit), with very variable latency, anywhere from 5msec to 100msec, and around 2% packet drops. Both outlets were on the same leg of my home power panel, I verified it at the breaker box.
I finally ended up putting up a couple Unifi Nanostation M2's (the bigger ones with the 10dBi antennas) aimed at each other through the walls to act as a point to point network, and it was faster and more reliable. Still not super fast, I get like 30mbit, but latency is a nice constant 7msec, with little packet loss.
But in a previous house, the walls were real plaster with metal lath behind acting as a faraday cage, and I had no choice but to use powerline networking (it was a rental house, so I couldn't easily run ethernet)
