Summary: I read a lot of the negative reviews and was a little worried but decided to give it a shot. It works great is way better than my weak wifi signal. I have the modem upstairs on the other end of the house (about 2500 sq ft) on a different circuit breaker than the intended outlet for this. I was worried about the distance and different breakers but it works fast with no problems. I tried a wifi booster and I still lost too much speed.
Summary: Have four of these units and they work flawlessly. Get very close to the same speeds as my desktop wich is directly connected to my modem. Hardly ever looses signal -- and when/if they do, a simple unplug/plug at all the stations solves the problem in mere minutes. Very satisfied. Wish they were wireless as well...
Summary: I was having trouble with the quality of streaming on my new SmartTV hooked up over wifi, which is on the opposite end of the house from the router. HD quality would drop to a pixellated mess randomly. After some research, I came across these little doo-dads. I read and read, trying to understand in my non-technical brain how they worked.
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). Cons: Powerline networking devices seem to get only 20% of the advertised speed.
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. I decided to upgrade to a newer version of HomePlug, so purchased the ZyXEL PLA401v4 HomePlug AV 200 Mbps Powerline Wall-plug Adapter kit. I unplugged the Netgear units, and then plugged in the ZyXEL in the same outlets, no encryption.
Summary: I'm very happy with this item. I've been using my ZyXELs for about 2 months now and it's worked 100% flawless.Installation went without a hitch - this baby was totally plug and play. My ZyXELs are plugged into surge suppressors, which I thought might cause a problem, but that works okay too.
Summary: We have a fairly large house and wireless doesn't cut it for a solid/fast connection. Currently we have this and 2 others (the ones with the pass through plug) for picking up the signal over the electrical wires and they have all worked great. I've had no problems with Netflix or other services being slow (but we do have fast internet to begin with.
