Summary: I just moved in a new house and my room doesn't have an Ethernet port. I don't want to stretch a super duper long wire from the router in the living room all the way to my room, thus the solution is this powerline adapter. Setup could not be easier, just plug one onto the router, other one to my desktop. I am very surprised that I don't lose any speed. My internet plan is 25 mbps and I get 28 mbps reading in speedtest.net.
Summary: This information is for the TL-PA511 model which I purchased from a source outside of Amazon but I would imagine holds true regardless! As far as I can tell the only difference between the 511 and 411 model is that the 511 has a gigabit NIC, so if you have purchased the 411 model then the fastest speed you will get from it is 100 mbps due to the slower NIC.
Summary: I'm getting 150-180mbps out of the 60 years old wiring of my house. Since I'm using the adapters between my computer and my home theater that's fast enough. On 2 occasions after a power outage the adapters would connect together but wouldn't pass any data. I had to unplug/plug them and redo the setup. I'll most likely buy another set soon.
Summary: I just got these to help someone for use in their apartment. That building had wireless interference all over, and some of the walls were concrete. A wireless signal there couldn't even reach 35ft. With the Powerline adapters, I literally just plugged them in and they worked instantly. I was worried that since the building was around 40 years old, that the electrical wiring might be an issue, but it wasn't.
Summary: I connected my PC (on the 2nd floor) to the router (in the basement) and I'm getting 100mbps without any packet loss, this is awesome!!! As expected, 3 floor won't reach 500mbps so it's not my "real" con: it is its power saving features that just won't work with my computer. Luckly, TP-Link have submitted a "beta" program to disable those features. So far I don't have any more complaints!
Pros: Reliable, plug&play
Cons: Won't wake-up when I turn on my computer, not full 500mbps across 3 floors.
Summary: I bought these thinking I can hook up my HTPC in my living room with my switch at the other end of the house. Turns out the wiring in my house is separate so they don't even see each other. Anyways, when plugged into the different sockets in the same room I get around 300Mbps which isn't bad. They are rather large with no passthrough. Also, they get pretty hot after a while.
Summary: This item is as described. In reading some of the other reviews, I believe the confusion is in the initial paring of the units. All I did was plug them into two different outlets in the same room (clearly they were on the same circuit) and paired them, I did not even bother to plug in any Ethernet cables. I then moved one unit near my router and the other unit to a distant bedroom, hooked up the Ethernet cables and everything worked as described.
Summary: Was initially worried that the poor wiring in my apartment would cause a problem, but none encountered. Increased the speed and reliability of my desktop's connection vs wireless. It also saved me the trouble of having to run an ethernet cable 30ft from my only phone jack to my desktop in another room. Wish I had found these years ago!
Pros: Easy setup, Access to a wired connection in other parts of your house
Summary: I've had this product for about a month. Would recommend for desktop users using a wireless connection.
Pros: Plug and play. Not sure about all the technical read/write download/upload numbers, but it seems to be working. Less hangups than the wireless connection I had. Also a huge improvement in latency while playing games like Battlefield 3 and Black Ops. My router is in the second floor while my computer is in the basement. Granted, I'm the only one in the house using this product. Everyone else uses wireless so I cant say much for how this product works with more than 1 p...
Cons: I wish it came with a longer cables. I think they're around 4ft, not sure, too lazy to find/open the box. But luckily I had a few of my own cables lying around. Also, not totally sure if the security works. Don't really have a way of checking it. I just pressed the only button there on both of the devices and hoped for the best. Guess I should've read the manual...
Summary: Using this kit for a smart tv, rather than wireless. Setup was incredibly easy and haven't had the same issues we had watching netflix with the tv's wireless connection. Only issue is some whine coming from one of the units, but only noticeable if the room is quiet.
Pros: Easy setup, great performance.
Cons: Small amount of whine from one of the units.
