Summary: After an hour of trying to get these two units to talk to each other, I gave up. The lights all said that they were connected, but the software said they weren't, and I could not even ping anything that was connected to them. They were in the same room, on wall receptacles, and with one on my router and the other on an opposite wall with a laptop connected, they never made a connection.
Summary: Basically, I bought this to add an Apple TV to my home network (hard wired) as my wifi was not close enough to get a strong enough signal for streaming media. The TP-Link was easy to setup and immediately fixed the problem. I played around with it plugging it into various areas of the house and the performance seemed good everywhere. The only issue I had was paring the devices. The instructions say press the pair button for one second and the power light will blink.
Summary: Quick easy setup...worked right out of the box...first try. Replaced a wired network connection. Internet speed test result with the powerline adapter is exactly the same (>30 mbps) as it was with the wired ethernet connection! Gonna buy a few more adapters.
