Summary: I've purchased two sets of these now for a total of 4. Typically 90% of the time, these work incredibly well.. high bandwidth, no latency or issues and they just work! I have them upstairs, downstairs, spread all over the house. On rare occasion they have issues, can't stream media and or just stop working. It's all of a 10 second fix by unplugging the non functional adapter and then it's good to go.
Summary: The PowerLine Network extenders perform as expected, but they can be touchy when trying to add additional units or changing the encryption code from the default which is high recommended since the original code is public. Sometimes the units do not want to perform in the "green" mode and will downgrade to a degraded transmission. Not sure why this happens but you can tell immediately by the lower speed you get.
Summary: I've set up several friends in addition to myself with this simple yet effective way to extend your internet signal. Works out great and took nothing more than plugging in the adapters and connecting the ethernet cables to get it working. Didn't even need to follow any instructions, it just worked. If you want a stronger signal in several rooms for things like Netflix viewing, this will do the trick.
Summary: I have an old house with lousy wiring. My expectations were low, but bought it on sale, so . . . Results are such that I couldn't expect more from this product.
Pros: Totally plug & play. Connected to router upstairs, back circuit. 2nd unit downstairs and will connect on front or back circuit. My Netgear WGR614 is probably dying - disconnects often, and only getting 12Mbs out of max 18 Mbs. With powerline attached, actually getting 20-22 Mbs - higher than I'm paying for. Have moved it around to various outlets for temp use, and always reconnects instantly. It's been flawless for me.
Summary: Bottom line is that this product works as you would expect. Simple setup with decent throughput. There is an issue where one of the units is emitting a high-pitched noise that can get very annoying. I contacted D-Link for an RMA and that entire process has been a nightmare. First, the tech forgot to enter my phone number, so when I went to enter my case number on the RMA site, it couldn't find it. I had to contact support again to get it corrected.
Cons: It only covers very short distance. Unless two are very close together, it will not work. I can't even get it to work upstairs in my house. Loss of internet speed (lose 60-70%) is another big drawback.
Pros: Was looking for solution to extend network connectivity in apartment. Bridging Wifi was not working consistently. So looked into Powerline. This is a great solution! Works flawlessly. Setup was simple as well. Great to extend wireline network reach where WIFI would otherwise be of low reach.
Summary: I added 2 of these to my previous DHP-306AV power line network and they connected on the first try and are working just fine. I especially like that they don't block the other outlet on a duplex outlet like the older model did. I may buy 2 more to replace my other DHP-306AV units as these are much less expensive than the older models. I'll keep the older ones for backups.
