Summary: I took the adapters out of the box and connected one to the router using provided cable and plugged it into the wall (not a power strip). I plugged the second adapter to the wall in the same room and connected it to a laptop using the other provided cable. The laptop was not able to connect to the network. I went to the web-site and downloaded the WD Livewire utility. I installed it and, at the end of installation, it reported "HomePlug Adapter NOT DETECTED".
Summary: After reading reviews I had very high expectations about this this product, it seemed like a perfect replacement for my wireless 802.11g network. There was no problem with the connection and installation, devices detected each other perfectly. However after that there was no network connection. Hmmm. I expected a similar behavior like connecting to a router, my bad. Ok, installed their software from the CD. Run the utility, it detected both devices just fine.
Summary: In my house the WD powerline AV kit worked fine IF the distance between the two adapters was within ~ 20 - 30 feet. Transfer speeds were greater than 100 Mpbs. However, when I tried to use the kit for a distance greater than ~ 30 feet to an outlet where all my audio/video equipment was set up the speed of the device fell below 10 Mbps. Turning off all the equipment didn't improve the speed. So I'm returning the kit.
Summary: I expected a simple set up process (it uses the electrical circuit after all) and a transmission signal strength equal to my router - 100 mbps . I got neither . Set up was confusing with four boxes; and passwords entered correctly for each box were flagged as incorrect . The "home" box has a password but there's no place to enter it , and a message stating "home box not connected" appeared which was not true.
Summary: I bought it due to reviews that said you just connected it up and it worked. Well after hrs and hrs of trying and on the phone with WD support (they also sent me to Comcast but they said it wasn't a issue with them) I give up. It not only won't connect my remote device but it won't even connect 2 devices on the same unit not going through any house wiring. It will connect one but not two devices. BTW my house wiring is only 3 yrs old and I'm using W7.
