Powerline adapter works as advertised, was 100% plug and play. I am amazed I could get internet through an electrical socket.
Unfortunately, the speeds it delivered, regardless of which outlets I tried, never exceeded 25/25. My 2.4Ghz wifi is giving me 40/20 or so.
Connecting direct through CAT5 gives 100/30, as does wifi over 5Ghz.
Not sure what else I could try.
