TP-LINK TL-WPA4220KIT AV600 Powerline 300 M Wi-Fi Extender/Booster/Hotspot with Two Ethernet Ports, Starter Kit/Twin Pack (Easy Configuration, Wi-Fi Clone for Smartphone/Tablets/Laptop)

Works fine once you get it set up. Setup is easy if you follow the right steps.I should point out first that if you're happy for the wifi extender to have a different SSID (wifi name) from your main router there really is no set up. You plug the wifi plug in where you want it and the non-wifi plug into a socket near the router and connect it to the router with the supplied ethernet cable. That's it. You're up and running. Log in to the new wifi with the password written on the wifi plug and your computer/phone/tablet will automatically switch from the wifi extender to your router as you go out of range of one and into range of the other. Or you can switch to the best signal manually in your computer's wifi settings. For the technophobes among you this is probably the easiest route but if you are even half-litereate in setting up a network then read on.It all works best if you use the same SSID as your router. If both signals are present your computer will just use the strongest one. The instructions in the quick setup guide say this setup can be achieved by pressing WPS buttons on the router and the wifi plug. Like so many others in these reviews that didn't work for me. I have a Virgin Super Hub router. Also, my laptop has no CD drive so the mini CD supplied is useless. Never mind. There are 2 ways to overcome this - both of which are partially described already in the reviews. I'll just clarify them a bit:1) Plug the wifi plug in but DO NOT connect the non-wifi plug. The wifi plug will set itself up with a local IP address of 192.168.1.1. So, just connect to the default wifi with the SSID/password written on the plug, type 192.168.1.1 into your browser and you'll be open a log in dialogue for the wifi extender's web interface. The username/password for the web interface is admin/admin (that's written on the plug too). In the web interface you can change the SSID and password to match that of your router. Then plug in the non-wifi plug and connect it to your router. Click the button in the web interface to "reboot" the wifi plug. That will save your settings and it will connect to your network. The wifi plug will get a new IP address from your router so you'll be logged out of the web interface but all your changes are already made. You're good to go.2) If you want to change the settings after you've connected the non-wifi plug to your router you'll need to know what IP address the wifi plug has been given by your router. I couldn't find that in the list of connected devices on the router interface. If I had a CD drive I could have installed the "utility" program that came in the box. But fortunately it's also available online for Mac and PC. You can download it here: http://www.tp-link.com/en/support/download/?model=TL-WPA4220&version=V1. This link is for a WPA4420 wifi plug. I ordered the WPA4420KIT but found the wifi plug utility better than the kit utility (which just found the non-wifi plug on the network). Depending how Amazon show these reviews you might find you have a slightly different model. No mind, just follow the link as far as ..../download/ and then browse to the model you have. The utility is a file called "powerline scan.exe". When you run it it will scan your network for the wifi plug and reveal its IP address. Then you just click on the "connect" button to open a browser window and connect to the web interface. The username/password is admin/admin unless you changed it before.If you have the non-wifi plug connected to your router, the router will assign the wifi plug a new IP address every time you reboot it or unplug it. That doesn't affect the SSID or password though so you can move the plug without breaking the wifi extension.And that's it. Easy. It did take me about an hour to work out the above but you have no excuse now. You'll be up and running in 5 minutes.I'm happy to report that since set up I haven't needed the scanning utility again and the wifi has behaved impeccably. All my devices just have constant wifi all over the house. It's really quick too. As good as being wired. I've moved the wifi plug a couple of times to get the best location to cover the whole house. It sets itself back up every time.

This is the first powerline extender that I've ever used and I'm very glad I bought them.I live in a 3 storey house and the main router is on the ground floor and my room is on the top floor, which makes the wifi signal in my room very weak. When I first moved in the house, I complained to the landlord that the internet is not working in my room, so he upgraded to Virgin 100MB service and Airport Extreme, thinking it might fix the issue. But it only improved the connection speed to only barely usable level, not been able to stream videos or play online games(haven't used my chromecast for a while and renewed my PS+ because of that). First, I tried a TP Link wireless extender that they already have, with no significant improvement on speed/stability. So I bought an airport express, thinking better quality product, might give me a better connection. It improved the speed a little bit, but I'm only getting around 5-10MB/sec where the actual service can handle up to 100MB/sec. So I did more research online and found out about these powerline extenders. I thought I'd give it a go as I thought it could be suitable for my situation and purchased them. The setup was so easy with these. I've plugged the 1st adaptor to the extension lead(I know it's better to use the wall plug, but because of the location of the main router, that's my only option), connect to Airport Extreme withethernet cable. Plug in the 2nd one in my room and pressed the pair buttons in the space of 2 mins(you can do that beforehand as well). Then, used the network name and password provided, and that's done, all set up.I've got around 30MB/sec straightaway and could see the significant improvement on the speed. I've hooked up my ps4 with the ethernet cable as it gives a 5-10MB/sec faster speed compared to wifi, now everything works perfectly. It's only been 3 days that I started using, but never experienced any connection drop or significant fluctuation in the speed yet. Now I can stream all videos and play online games again. Happy customer!!I would recommend this product to anyone in the same situation as me. My suggestions would be: to use the wallplug if you can, use ethernet cable where possible(to your game console/smart TV that are stationary as it provides 2 ports) and move around the 2nd adaptor in your room to see where it gives you the best wifi.
