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)

I placed these in the outlets 2 rooms apart pressed the "Pair" buttons and worked instantly. Sky downloads on catch up much faster than before. Extremely pleased. Can only comment on day 1 but no need to anticipate any problems.

Having tried without success to get my BT extenders to work, I bought these TP Link G.hn2400 extenders which worked perfectly first time and have continued to do so without interruption. Very pleased.

Works great - If this is all you needBough this back in the Amazon spring sale, had a quick look figured it was what I needed to add internet capability to the garden room I'm getting built in the summer.Finally got round to setting it up yesterday. Couldn't be easier, plugged the appropriate bits in to my router and put the extender end in the garden shed - Brilliant I now have around 500 Mbps where previous I could barely pick up the house wifi and was getting about a hundredth of that.Next step - order another extender - The instructions clearly show how to connect multiple units to cover a large area.Part number fine PGW2440 is what I need. Type that into the amazon search box. Returns a huge selection of adapters, inclining this kit. However none of the others are what I need.After a few minutes I search else where. Increasing confusion ensues.Eventually I come across an Entry on the TP-Link bulletin board, where many others have found that same problem.One had an official response from TP-Link confirming that additional extenders are not available separately.The only way to obtain one is apparently to buy another kit and bin the adapter.WTF!!!!!Maybe something else will work with it who knows? The internet is unclear.I would probably send it back, but I'm past the 30 day return period, and what I DO have works great.Absolutely F---ing ridiculous policy.

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.
