TP-LinkWired Passthrough Powerline Adapter Starter Kit, Advanced Protocol G.hn MIMO, Extra Power Socket, 2+2 Gigabit Ethernet Ports, No Configuration Required, Plug and Play, Pack of 2 (PG2400P KIT)

** UPDATE **My latest update after a month of use didn't alter my rating, but I have seen some other buyers experienced sudden drop out signals and I did indeed experience that too myself. Upon some researches, I found out that you need to check and update the firmware of the units. This can only be done via the utility software that you need to download from TP LINK website. This is frustrating as the packaging did nothing to mention this nor has an instruction to show how to update firmware. Yes, it's plug and play but I knew that these day an age, all 'connected' device would have the ability to enhance and repair any software faults. This is totally the case. My unit came with the original firmware 1.0 and the latest is 1.0.2 (two version up since its launch late 2022). Apparently they have fixed some problems and to be frank, I've in day three after updating, and there's no drop outs. So far, it's very consistent and the speed is as fast as before. So, before returning the units, check this first. **At time of writing this review (Feb 2023), this is TP-Link's one and only G.hn Powerline network adapter. There are other brands out there but since I owned and used the previous and older generation TP-Lnk HomePlug AV 1000, I thought I should stick with the brand as it never gave me problem in terms of reliability. For those who haven't had much experience or knowledge about power line network adapter, it's pretty cool if you want to reach to dead spots around your house that even the latest Wifi network can't penetrate (i.e. thick brick walls or even out house or garage), as it's using the power line as if they are network cables.The problem I had with the original AV1000 was speed. While it worked, the speed is at best under 30mbs, and I have a 500mbs fibre broadband (and I do get 480 in the house wired). So that's less than 10% of the speed. I won't expect full speed anyway as my own MESH network can't reach near that inside the house. But having read about the newer standard G.hn (that also replaces HomePlug AV technologies, which they also declare that the old standards will be obsolete and won't be updated as of last year!), so I took the plunge and went with the new PG2400 model instead of the other faster TP-Link HomePlug AV2, since it's reaching the end of life by the sound of it.To my surprise, the speed is almost triple (see speed test in my pictures). Now, I can run livestreams in my office outside of my house, even though it's only 80mbs up and down, but it's more than sufficient for any high quality streams and remote work, as there's only one computer and one smartphone in my small office, unlike my main house, where there are more wireless devices connected at any one time. So this is awesome and well worth upgrade. Despite TP-Link didn't mentioned anything, I believe this is Wave 2 and not the original Wave 1 that has a speed limit of 1200mbs, this has a max theoretical 1500mbs (Wave 2 can go unto 2500!).Anyway, this is an awesome product and save me time to lay network cables (may be faster but a lot of work needed to route the cable from my router, around the house and to my office, on top of all the networking needs to be done in the office!). This is a plug and play solution and that extra power outlet allows me to plug other things on top too! Great stuff.

Used to get wired network to TV without cable.Better than wifi, more reliable.So easy to set up, and less hassle than running a network cable around the house.

So I purchased these as I recently got a TP-Link router, which supports OpenMesh/EasyMesh. And I saw that the “Access Point” which came with this kit also supported Open/EasyMesh. Thought they would go hand in hand, single management pane, all part of the same eco system. Along with that, I like having an Ethernet port for my work and personal computers to connect to.Set up was easy, pretty much plug and play, and then enabling the OpenMesh setting from my routers management page.Initially I started by plugging the first power line adapter (the one that should really plug into your router) right next to my router. Short Cat6 cable, straight from the router, to the PowerLine adapter. I placed the larger unit (With the built in AP/Repeater/Mesh node) into the wall, up stairs in my office, by my work station.Using the TP-Link utility, I was able to see that the transfer rate was only showing up as 445Mbps. Which wasn’t actually any better than my previous Generation AV2 TP-Link PowerLine adapters - I’d say the same actually.Here’s where it gets interesting, and kind of fun (especially if you are a DIY home network ‘boff’ - like me.) I went round my home, trying all different plug combinations. And running internet speed tests along the way. I’ve had speeds vary from 80Mbps all the way up to 400Mbps. It actually did peak at about 580Mbps on one of the tests. Do keep in mind that during these tests I was merely testing the LAN speeds (Through only Ethernet) on the AP/Repeater part of the PowerLine Kit. My last kit only ever hit 150Mbps, in what I determined as the ideal setup.Now for the funny part. With the PowerLine adapter close to the router (1.5 metres) I was getting the slower speeds. I forgot to mention; my router is right next to the RCD. So I’d expect a lot less latency, faster speeds, and less power cable for the signal to be sent through. It should have been ideal. However, with the PowerLine adapter the other side of the house, the speeds were faster. So through even more power cable, more Ethernet cable, and likely a lot more interference, the speeds were faster.I know it’s not advised, but I recently plugged the bigger of the two PowerLine adapters into a non surge protected power strip. Speeds increased yet again. So 2 meters of Cat 6, and 10 meters of electric wire, is slower than 20 Meters of Cat 5e and I’d estimate 25 meters of power cable. Confusing, eh?I guess it just goes to show that these adapters are not all built equally. And even the smallest change can affect the speed. If you do purchase these for the PowerLine functionality, test them in every possible combination you can. Even if you have a two gang socket, try them in each socket. I gained 100Mbps just from going from the right socket to the left socket. Saying that it does worry me how that could be.Lastly the mesh set up… well it’s my first mesh set up, and I’ve found the speeds to cap out at 420Mbps over WiFi when connected to the mesh node. If I connect directly to my router through WiFi 6, I get the full speed I pay for. I’m not sure why this is or what I need to do to improve it, but I will be sure to update my review once I find out.All in all, fast power line adapters, a lot of trial and error involved to find out what setup works best for you. The WiFi speeds whilst set up in Mesh mode aren’t that great. Although the signal is stronger, the speeds are now slower. I do however recommend these especially if you are paying for speeds below 500Mbps.

Using iperf to test bandwidth, these G.hn2400 provide exactly 3x the TCP bandwidth of my Homeplug AV2 1200s. I note that the PHY connection speed is approx 2x better not 3x better, so these must be 30% efficient versus the 20% efficiency of the Homeplug AV2.Using ping to test latency, these are better in one direction (4 ms) but much worse in the other (14 ms) whereas the Homeplug AV2's get 5ms and 6ms each direction respectively.I tested with the vDSL compatibility option disabled for both, and power saving disabled for both. There are two Homeplug AV2 networks in my house, and one of those networks was running during both tests which may have impacted the G.hn2400 more perhaps as it's a completely different protocol, and they all use the same spectrum.In short, I am impressed. The newer G.hn protocol is a marked improvement over the AV2 protocol.
