G.hn Wave 2 Powerline Ethernet Adapter PoE – 2 Gigabit Ports, 30W Power Budget, Supports 802.3at PoE, Powerline 2000, Plug & Play, Ideal for Gaming, Work, etc., – Single Device (GPL-2000PoE)

I've been using powerline adapters for about 8 years, and decided to upgrade my network to the new g.hn Wave 2 adapters that are coming out.I really liked that Comtrend/NexusLink has a "complete line" of adapters that leverage the same g.hn tech but perform specific functions. This POE adapter is especially useful, since it simplifies connecting devices like security cameras as it will power and connect the camera with a single cable, but also simplifies the back haul connectivity since the g.hn can use the power lines to connect back to the router.I have a network using 3 of the basic GPL-2000PT adapters and two of the GPL-2000WAC access point adapters. I bought the POE device for a security camera at the far end of the house that had poor wifi connectivity. After initially getting the POE adapter, I wasn't able to get it to pair with my existing network using the "link" buttons. I tried multiple times and multiple ways, but the POE wouldn't join my existing network.I emailed support and they sent some instructions over email to try. Those didn't work, so I ended up getting a call with them. The support tech I spoke with was very helpful, and we tried a few more attempts but we still couldn't get it to pair, so he issued an RMA and sent a replacement out.The replacement shipped quickly, but to my frustration the replacement also wouldn't pair with the network. However, the replacement POE and original POE adapter would pair with each other. At this point, I believed the issue might be either my other adapters, or how I had set up my network. I gathered all of my adapters together and did full factory resets on everything. Starting from square one, the POE adapters would pair with each other, the PT and WAC adapters would pair with each other, but the POE and PT/WAC adapters wouldn't pair together.All of these devices have built-in web interfaces that can be accessed by connecting to the network port and going to 192.168.0.5 (all adapters use this IP by default). On the main page, there is a "Domain Name" under "Basic Settings" and "Pairing Password" under "Encryption Settings". These are the two items that need to match in order for the devices to join the same g.hn network and talk with one another.I first tried changing the "Domain Name" to match from the web interface. Doing this allowed the devices to "see" each other, however they couldn't pass data and wouldn't pair using the link button. I then changed the "Pairing Password" from whatever the factory default is to something else, and to my surprise the POE and PT/WAC adapters paired successfully!I always used the "link" button on the sides of the devices to link them together, so I never changed these manually from the web interface before. As such, it seems whatever the factory default pairing password is on the POE devices is different from the other models, and it looks like this has to match in order for the "link" button to pair successfully. So if you buy a POE adapter and are also struggling to get it to pair with one of the other models successfully, try manually changing the pairing password on both from their web interfaces to match.I relayed this information back to support, and they let me keep both POE adapters as a thanks. I'm really pleased with the way these are working, and I'm also very happy with the level of support I received. It's inconvenient that the POE and other models can't *currently* (as of 8/2020) pair using the link button, but there's a solid workaround, and I'm sure Comtrend will investigate further and release a software fix. The other thing I like about the company is they actually appear to support their devices with software updates and bug fixes, whereas most other vendors of powerline network adapters just ignore them after they get released and bugs never get fixed.Even if this was just an issue specific to my set adapters and isn't a problem for anyone else, I learned something in the process, which is always worth the effort.

This was paired with a NexusLink GPL-120OPoE model, and it was as easy as plugging it on the wall outlet and pressing security button on the first and then on the second.Of course, they’re different models and speeds, but the throughput I got was well below my WiFi when testing with a laptop. I was getting an average of 65 Mbps. That’s many times slower than the advertised for the NexusLink GPL-1200 let alone for this model, GPL-2000, which is rated for 2Gbps. The latter was downstairs directly connected to the router and the other upstairs at no more than 60 feet away.However, it clearly seems that the issue was not with this unit. Connecting directly to the GPL 1200 with an RJ-45, my laptop saw that connection as 100 Mbps instead of 1 Gbps (1000 Mbps). When connecting to the GPL 2000, it connected at 1 Gbps. That means that this Nexuslink could theoretically get a much better speed if it was connected to another GPL 2000 or even to the GPL 1000 if it was not limited to 100 Mbps.Since I had ordered this for one of my cameras that I didn’t want to run cables to, it worked very well for that. It didn’t require too much bandwidth and the power provided by PoE was perfect for the camera. My main objective was met.There could be many reasons for that lower speed, such as both being on different electrical circuit breakers or some type of interference. But I believe that the main reason is that the other unit has an issue, which I hope to work it out.From what I see, this works well. Unfortunately, my issue didn’t allow me to test it under better circumstances, but even at the speed I got, it proved to be good for security cameras and I would say even for most video streaming services and regular internet browsing.

I have 4 G.hn wave 2 powerline adapters from NexusLink. Two of the GPL-2000 and two of these GPL-2000PoE. 3 of them work flawlessly. Signal is much more stable than AV2 standard. I use these for PoE cameras since I have no attic or crawlspace to pull wires through. I'd give 5 stars except one of these GPL-2000PoE is faulty. Not only doesn't find a connection, but takes down all of the other adapters if it's plugged into the system! I'm returning it for a replacement, and will update my review after.Update 10/5/2022:Received my replacement GPL-2000PoE a couple days ago and now everything is working perfectly. I moved from AV2 powerline and the difference for me at least is night & day. Previously I had to lower the resolution, framerate, and bitrate on all my cameras since I'd get dropouts otherwise. I can now max everything out and latency is 1-2ms on all cameras now.

TLDR: They're bad. Buy a network cable instead.FYI the instructions (see picture) list a good connectivity of more than 40Mbps, which explains the numbers below.Bought these because I have poor wifi connectivity on the other side of the house. Idea was to get two of these to bridge the gap (admittedly I didn't need two PoE ones but bought two to test them out) and put a wifi AP on the other end.Connecting them to each other was pretty trivial. Ran CAT 7a to the source adapter and 7a from the end adapter to a laptop with a 1Gbps NIC.Ping? 7ms. Great.Transfer rate? 40Mbps up and down. (um, what?)Fine. Tried it throughout the house and even in a few outlets in the same room the source adapter is in. Max transfer rate after all that? 180Mbps in the same room (worse outlet was again 40Mbps). Slower than if I just ran a 50ft cable.How far is the original outlet I tried? In a straight line about 70 feet.If you need something to bridge the gap, do not use these. You might as well run a cable.
