That is what finally convinced me to look again. The ones I now have work very well. DirecTV had one made where the component end is built into a surge suppressor power strip. Very handy. It protects the ethernet port as well. I put a switch on that end and tested throughput to my servers at the other end. It performed as advertised, and now my PS3 lives on it as well as the DirecTV receiver. Ping times on the PS3 in games like Red Dead Redemption, which uses GameSpy to connect users, seem to be very good. I have a reasonable wireless set up and reception to the PS3 was good, but the ethernet over powerline provided better throughput for downloads and media sharing, and since the ping times were ok, I went with the wired set up and have not seen any trouble. It will be a year in September with no issues. These behave like a server/client technology. The Powerline 'server' can feed more than one powerline 'receiver'. So its a bit tricky to get the right parts, depending upon brand and model, and level of technology used. A level 1 powerline device cannot be used with a level 2 device. Most new units are all level 2, and should work together regardless of brand, but I have not tested that. But the technology in general has come a long ways in the last couple of years. Its worth checking out.
