TP-Link AV1000 Gigabit Passthrough Powerline ac Wi-Fi Kit, Dual Band Speed Up to 1200 Mbps, Wi-Fi Extender/Booster, Extra Power Socket, No Configuration Required (TL-WPA7617 KIT)

The powerline functionality is the best to reduce latency and other issues faced during gaming. I experience no lag or disconnection issue generally seen with WiFi. The app is easy to use with instruction and easy setup. Extender functionality is an added bonus and stronger than most WiFi routers

Thanks ! Straight forward and suited me just well.

EDIT after 3 years of usage: I can confirm it works ultra reliably. I get a stable 600-700Mbps over the wireline connection. One key factor is where you connect the devices, ideally they should be on a single ring with no spurs. Additional spurs of extension cables used in between deteriorate the signal, if you keep it in mind and plan accordingly then it works wonders. Not a single reboot needed in 3 years of constant use. I had honestly been sceptical about it working over the power cables, but it does work perfectly. Make sure you plug it directly into sockets and not via extension leads, especially if they are loaded with other devices as the speed may drop significantly (or not be able to connect at all), so rather run a longer Ethernet cable to the nearest socket than an extension lead from it. Note that you need the main unit connected to your router, and the secondary unit (or several units) where you want it in your house. I can achieve close to the nominal 1Gbps when they are on the same ring, and slightly less when on different circuits. It works for me accross circuits but I suspect that it may to some extent depend on your fuse box, the manual recommends of course connecting both to the same circuit which indeed works best. One additional good thing is that, unlike typical wireless extenders, the primary and secondary units do not communitate wirelessly so do not cause extra interference of use up the bandwidth. Having said that, you have 1 Gb Eth port to use, but can also use built in 2.5 and 5GHz Wifi as either an extension of your home network, or as a separate network. Setup is easy, you can just plug them in and they work. You can additionally pair them (which you might want to do to avoid others trying to connect) by just pressing a button on each device, and clone your main wifi settings by pressing another button and the WPS button on your router - which you can use to extend your Wifi network. No need to connect to it to configure anything - but if you want to, you can do so via an app, web interface (via its wifi), or desktop tool. You can configure quite a lot of things actually such as MAC filtering etc. if you wish. Highly recommended.

These work very well in houses where WiFi signals have issues due to brick walls and other obstacles. They will work across different circuits with varying levels of success, from fairly good to ok for controlling lights . You need to try it and the connection does improve with time but can vary throughout the day depending on what electrical loads you have. I have had both TL- WPA8631P and TL-WPA7617 kits all working together but now only use the single Ethernet plug (to my WiFi router) and the two WiFi plugs (one with a mains socket and 3 Ethernet connections, one with just one ). The plug on the same mains circuit regularly gets over 180Mbs and connects our 4k tv plus tablets and phone back to the router (plume based). The other gets between 35 and 75Mbs and creates a bridge to the WiFi in my shed allowing me to stream audio or YouTube videos without issue as well as other ‘hard to reach’ network devices. The tpPLC app is useful for showing status and basic setting but changing any network settings will take you to a web interface which can be fiddly. The only reason you might want to do that is to block a device from connecting if the signal is strong but the connection not good enough, or to alter the WiFi power. Do not alter anything else otherwise it may not work properly. The WiFi plugs can appear on your Tether app if you use it but can be hit and miss. It is useful but doesn’t have the same configuration capabilities .

Had really poor wifi in my house due to lots of internal solid walls/distance from router and wanted a cost effective way of getting a better signal towards the back of the house. I think you need decent electricals, fortunately my house was recently re-wired and it paid off as this works way better than I expected. Easy to set up, quadruples the wifi speed in my dining room, and has worked reliably for about 6 weeks now. Can't fault it.
