Summary: Pros: Very convenient and more reliable than wifi. Also supports easily adding additional AV 200 nodes (I have 3 that talk to each other, to bridge wifi-enabled APs/routers/switches in the family room, office and upstairs guest room).
Summary: I already own the Netgear 85Mbps Powerline Network Adapter XETB1001, which I use to stream HD 1080 from my server, it has worked flawlessly for 2+ years, a single HD stream requires ~6.6Mbps bandwidth to work well.
Summary: Recently purchased this product. I was immediately pleased that the signal reached throughout my 1909 house from the third floor to the basement. Setting up the secure encryption, however, was a nightmare.
Summary: I bought this device to work together with a couple of linksys pl 200 power line devices. The device would not recognize the other adapters at first, I had to use the cd and plug the device to a pc in order to recognize the homeplug compatible devices.
Summary: Initially I bought a pack of 2 of these, as I have previously used Zyxel HomePlug units (the earlier 85 Mbps units). For those who worry about these things, these units do not have mains pass through, so you do need to have enough sockets in appropriate places to work with.
