TP-Link AV600 Powerline Adapter Wi-Fi Kit, Wi-Fi Booster/Hotspot/ Extender, Wi-Fi Speed up to 300Mbps, 2+1 Ports| N300 Mbps+AV600 Mbps plug and play, (TL-WPA4220 KIT)

Brilliant. Successfully extended wifi via powerline from very front of the house to wired cabin at back of garden, distance of around 120m or so. I'm guessing the electric is on the same circuit as the original house. Getting same speed as when connected to main router. Set up was easy. Connected to router, plugged in, waited. Plugged in extender, paired powerline via pair buttons and then used WPS to clone the wifi name and password.

I am a network engineer and I bought this for a job I had to do for a client which involved getting a wifi signal to a set of remote gate posts on a property for a smart intercom / doorbell.This product for me was both vastly cheaper than buying the amount of cat5 (ethernet) cable I needed and a million times easier than running it down the side of a very long driveway.I am incredibly impressed with this product and I use TP Link powerline networking gear a lot but the first time I used this model with the wifi option which not only worked really well the wifi signal this plug produced was very strong and rock solid and could be picked up from a considerable distance away.Setup literally could not be easier you simply plug the smaller of the two plugs into a electrical socket and plug one end of the supplied cat5 (ethernet) cable into the plug and the other end into the back of your broadband router (or network switch / patch panel etc). Then plug the bigger of the two plugs into a electrical socket in the area you want the extended wifi signal in. The bigger of the two plugs also have a ethernet / network port on it so you can plug a cable into it and then into the back of a computer, tv, games console etc and still benefit from the wifi extension too.Take it from someone who knows their stuff when it comes to this carry on.... this is a excellent piece of kit made by a manufacturer who is unable to make a bad product... TP Link are superb. The price paid is a bargain full stop but as I said above given the cost of the cable I would have to have used this for me was the bargain of the century and saved me a back breaking day of pulling cable.Cannot recommend highly enough... it's a no brainer ladies and gentlemen!

The Good:- It did speed up the Mbs in our wifi black spot (from a pathetic 12 to 30+)- Pairing the device was very straight forward.- Seems to work okay if plugged into an extension cable (but you might get lower speeds)The Bad.- Cloning the SSID from hub to the unit via WPS doesn’t work (work around below).- The app is pointless. Don’t bother.- The wifi seems to give faster speeds than connecting via cable? Very odd.- The drop off is significant. The speed of the wifi at our hub is around 100mbs but the best I can get from the TP-link is 44 (more usually in the higher 20s). That said if you have a dead spot that’s better than nothing!Other things to note.- For this to work the two sockets do need to be on the same wiring ring. For us the dead spot is in the converted loft (on a different ring) but bridging the gap by installing between floors has done the job.- You will need to clone the SSID / Password to make sure you don’t have sign in to two different wifi networks. The simple way is to press the wifi button on the unit and the WPS button on the router. This didn’t work for us. Don’t bother with the mobile app. That won’t help either. Search for “TP-Link Utility” in google and download to a laptop. From here you can set the SSID to the same as the one you currently have and the same for the password. Once you have done this as you walk round the house your device(s) will connect to the strongest signal.Overall it’s pricey and needs a bit of time, patience and IT knowledge to install (if things don’t go as per the instructions). BUT, I can now get strong enough internet in the home office so I don’t now freeze during Teams Calls… I’ll be needing a new excuse for dropping off those now.

TP-Link TL-WPA4220KIT is very simple to setup using the clear instructions. I didn’t ‘clone’ my existing WiFi network via WPS as I wanted to be able to identify the TP-Link extenders while I experimented with possible locations. Out of the box, all I had to do was follow the excellent instructions to pair the two Extenders (a second extender bought separately) with the Adapter. The kit worked perfectly without doing anything else; the two TP-Link (WiFi) extenders somehow manage a single, overlapping, WiFi network that covers the whole house - absolutely brilliant!Don’t expect to get quite as good coverage (in a ‘difficult’ site) as you might be getting from a good WiFi router. If you’re in doubt, it was cheaper to buy the kit with two 2-port Extenders rather than buying a second a few days later as I did. If you need more than 2, check prices carefully; from Amazon, it was much cheaper to buy a second complete kit than a single (new) extender.With 2 extender units sited to cover the whole house (massive interior and external stone walls), coverage is seamless as I move around the house with my tablet. Multiple extenders run a single WiFi network – brilliant. You just plug each one into a wall socket near the single Adaptor, pair it with the adaptor, then move it to a suitable wall socket. This means that experimenting for best coverage could not be simpler, just move extenders to different sockets – but do switch off sockets before (un-)plugging.TP-Link tell you not to use extension cables – I had no choice (the power socket close to my router is on the skirting board too close to the floor (listed house), and I’ve had no problems with a simple 2-way extension cable. I suspect it’s multi-way extensions with power indicators, suppressors etc., that cause problems. My 3 TP-Link units are on 2 different ring-main circuits and there’s an RCCD on the consumer unit. I can’t think why going through an RCCD (outbuilding) is likely cause problems, but don't know for sure.Because my new 4G mobile router has to be in an attic window to get a decent mobile signal, I couldn’t put it in the same place as my redundant ADSL router located where it both gives adequate WiFi coverage of most of the house and can be connected (wired Ethernet) to my printer and PC. The 4G router connects to the whole house via the TP-link network: router directly to the TP-Link adaptor (ethernet); extender 1, in place of the ADSL router, via Ethernet to printer and PC and gives WiFi coverage to the middle of the house; extender 2 provides WiFi to the kitchen and the rooms above – where the previous WiFi was patchy.If you really need to tinker with the set-up (e.g. change network SSID, password etc. etc.) there’s a good, intuitive, browser interface.
