TP-LINK PowerLine Network Wi-Fi Range Extender Review – TL-WPA4220KIT

Buy it on Amazon – (affiliate link)

This is a very affordable and useful powerline networking adapter from TP-Link. It consists of two powerline ethernet devices – one that connects to a router, and another one that has two ethernet ports and a built in wireless access point.

When both are on the network the two port + wireless adapter will route all of its traffic through your home’s electrical wiring to the other device. It works quite well and is an easy way to extend a network without having to run ethernet cable.

I have found that these devices are rarely a replacement for ethernet. In many ways they’re better than wi-fi but I have never come close to getting the promised 500 megabit speed that this and other products tout. The reality for me is closer to 100 megabits and that is when the devices are connected to the same outlet.

In a real-world application the best I can pull down is about 30-40 megabits of sustained speed. That speed is more than adequate for web surfing but probably not as good for more demanding applications like Blu Ray media serving and other high bandwidth applications.

But on balance this is the best powerline kit I’ve reviewed. So if you’re in the market for one this is certainly one worth considering.

Mark Allen says:

hehe, love the Euro plugs being used in a US electrical socket on your diagram 🙂

Sophia Cypria says:

Hi there can you tell me if these TP Link Powerline Adapters will they only work with Fibre Optic Broadband connections?

Brian H says:

I thought there was security key. thanks.

Nuno Oliveira says:

The 500Mbps are for powerline-to-powerline… The LAN ports are 100Mbps and that’s the maximum you can get from this device. A good thing is that you can have several multiple connections all running close to 100Mbps.

Jackdaniel Sung says:

hello there. i just saw your video. can i plug one side from my neighbers house and the other side plug in to my room. will that increase the signal?

ADK Rick says:

I have this unit and was working great for two months NOW it keeps saying that there is no internet connection …Need help.

Hannes Zietsman says:

Thank to this video i bought the junk! it works great 1 day but when the IP lease expires it drops the wifi. this is a known problem that TP_link can’t solve. Don;t buy stay away!!!

M.A.G says:

if you set it up can i connect to the modem and can i connect to the powerline extender?

cashfan3 says:

Ok I know I’m a little late but my router is downstairs and my ps4 is in my room. I can’t run ethernet up to it and I’m looking into buying this. I currently use wireless and believe it or not I get 2mbps on a great day download speed, and anywhere from 100-700 kbps upload speed. (Ik that’s TRASH). Do you think this will significantly increase my speed for gaming? I mean I can constant 2-3 bar on cod and in gta I lag out after 15 minutes in every session. I NEED HELP! Please and thank you.

LenoxOnYoutube says:

So does this pretty much mean ur playing Ethernet while Having wifi? Or am I getting something wrong

Alasdair Gordon says:

I live in an old sandstone house. My laptop is in the basement at the back of the house and my router is upstairs. I could only get a very weak WiFi signal in the basement and powerline has been the answer. I am not technically minded but I had my TP Link adapters out of the box and working in a matter of minutes. It is recommended not plugging these adapters into a power strip so the (more expensive) pass through versions are especially useful as you can then plug your power strip into the adapter. No software or complicated configuration is required – it is literally plug and play and the adapters “find” one another quickly. If you want to create a fully secure network you can press the encryption buttons. I have personally not bothered as no one else has access to my house electricity. I now have a reliable broadband connection for my laptop thanks to powerline.

Dincorta says:

Great video, thanks for the help.

Gepo de Mesa says:

does it work if you put them on different floors? One is on the ground floor and the 2nd one on the 2nd floor for example?

nathan t says:

I just bought the Av500 starter kit (TL-PA4010KIT), and it works great. Easy to step-up and use. My wifi signal was giving me 8-14 MB. Now, with the powerline, I’m getting ~50 MB, and no lag when playing games ~23 ping.

However, the adapter on the outlet does get pretty warm.. is this normal? Will it overheat?

GuyUDontKnow says:

i bought this 2 weeks ago and now im net getting further,
i set it up like the Manual told me. But now i have TWO Networks
but i want only 1 can somebody please help me?

[darebear_15 ツ] says:

does this work if i plug the first piece into the router and the other piece into an outlet at another house?

Ordieson says:

How does it do for gaming?

ICantSpellDawg says:

Hey Lon,
2 years later, what product would you recommend for extending 5 GHz band?

David Keane says:

Hey, cool vid.. I bought the 600 wifi one.. The phone can find the connection but the laptop can connect but no internet found? Any ideas please? The phone is at max internet speed now!! These plugs are magic!!

Carlos D Figueroa Gutierrez Del Arroyo says:

I have tried connecting it for 1 whole day and I yet could not figure it out. The problem is when I take it to another room far from the router.

Jelly Belly says:

I need help! I just got this today and finished the setup. Using ethernet from the powerline extender to my computer, i’m only getting 20mbps max. That is the same as my 2.4 ghz speed but I can get 80+ mbps on 5ghz on my other devices (ipad, iphone). How can I get the same speed as my 5ghz speed which I’m paying for on my pc?

Og Or says:

OR…for about $15 you could run a cable directly from the source to your remote device.

Daniel Ridell says:

Since this extender goes through the powerline, will the connection still be strong enough to play games, stream movies even though im a couple of rooms far away from the first device who’s connected to my router?
Please answer quick!

Tazzwar Azam says:

does my router also have to be from tp link for this to work?

Dark Exsphere says:

so you get 900mbps speeds directly wired….. but with powerline that says you get upto 500mbps… you actually get <100mbps.... weird

my PC gets 25mbps down and 10mbps up. and with powerline i get the exact same thing. same thing with wifi too actually..

HTB Dog says:

So yeah im a dog and i can run cat5 so i do that because powerline sucks

Meneer Doeterniettoe says:

Bought this yesterday, will return it today. In a small appartment (55m2) it does not provide a signal with a normal range. The signal is 50% lower within 7 meters in a straight line, in the next room (single stone wall, door open) the signal is a even 25% (that’s 4 meters from the extender)

Retro Moto says:

Have you thought about actually demonstrating how to set up?

mat0091 says:

my security cameras DVR box requires an Ethernet cable connection to my router (located 50 feet away). Can I use the powerline adapters instead?  thanks

akuma6099 says:

Excellent review. Clear and to the point. Thank you. I was really excited to see Metroid II: Return of Samus on the shelf back there. Ahhhh…….memories.

Alex Saplala says:

Great video. A quick question…..what is your download speed from your router….? That would give me an idea of how much degradation there is in the system. Thanks

Tech Hindi says:

good work and i have speeeeeeedy speed

That one guy Jared says:

Would this be good for gaming?

Merkzilla Edits says:

is there a way I can plug in 2 at the same time?

you tube or jakethesnake11 or JGG says:

Andrew John Simpson says:

TP link are offering refunds of this product…..Because it’s slow! My 100mb goes down to 8mb download speed through this product TP link AV500

Jonathon Jackson says:

can you use this on your ps4?

SEAMOSS69 says:

Nicely done. Helped me with my choice/purchase. Works well in Basement for Fire TV

jackster1212 says:

Am I living in some kind of alternate universe? I ask because I’m ecstatic if I get over 10 mbps… and here’s yet another person saying that 30 Mbps is “meh”… and not enough for streaming video (which we are still able to do at our more modest speeds).

TheGSummit says:

What will you guys recommend for video transfers/ and playing Smooth 4K video. I have the tp link 2000 and I can’t play smooth 4K video am getting 8up 15down and it’s still not playing a 4K 30f video smoothly I have a apple extreme in the living room and. iMac in the bedroom any ideas would help! Thanks


I pay for 100mbps with these i get around 80-90mbps

Kouta Fox says:

Does this create a separate hotspot for wifi?

Castillo Sound & Lighting says:

My dilemma is that I am able to get a good Wi-Fi signal using my phone as a Hotspot. But I am not able to share the same network so that both computers/ tablets etc can talk to each other while I am using my hotspot. Would this device help me share the same network connection between my electronic devices?

Alexander Mayr says:

Wie muß es Leuten damit man weiß das es registriert is mit den WLAN ? danke

Graham Stewart says:

mine disconnects multiple times a day. is that normal? does anyone have one of these that doesn’t cause consistent disruption?

Woogie .Z says:
