I have to begrudgingly agree with you. A couple years ago I plopped a couple powerline adapters on either end of my house. They're on different circuits, but the same phase of the panel.
It worked great. I got a consistent 80Mbps through them. I was happy and probably commented here or elsewhere about how they can work, or, "don't dismiss it, it might just be the trick."
Well, now they're pretty flaky. They still work just enough for me to keep using them, but other WiFi issues I'm having are convincing me that I gotta stop being lazy and run some cable to all my rooms. (I even have a crawlspace! It will be relatively easy if I can just get cracking on it.)
I don't know what changed between then and now. Phone chargers on the circuit? That random smart plug I bought last year? My A/C cycling in the summer? Doesn't matter. Powerlines are a hostile environment for high-speed data.
