Honestly, if you don't know how something works, stay quiet and don't confuse others or read the description before you share your knowledge. Some might think you're an expert or something :disappointed:
It uses wired connection, no wifi connectivity over this particular kit is possible. These are a brilliant idea if for example your router is away from your pc and you want a stable, wired connection.

These DO NOT give you wifi.

I've got 4 of these running in my house and never had a problem with them. Good price.

looks good, ordered cheers OP

I'd wait for the first comment deriding the lack of gigabit ports but as I'm using one of these myself (and they are extremely reliable) I may have to wait a long while... :smiley:

Can someone explain to me the advantage of using these?
Is this instead of connecting over wireless, you can plug 1 upstairs, 1 downstairs, and connect via ethernet?
Does interference play much of a part?

ive got a devolo unit but getting additional units are more expensive so might by these as buying additional units is more cheaper.

These DO NOT give you wifi.

same price on Amazon

Fair enough, i think i understand, however i'd point out that they don't give wifi, they give you an ethernet port to plug into.
Im more curious at how much their connection speed can deteriorate.
If i place it on the other side of the house, would they be similar speeds to a wifi connection?

This is not what they do at all!!

These allow you have another wired device somewhere else in the house (or use a switch there too for more ports)

This is what you need to extend your wifi. Got 2 of these and thay are very good

It's mostly down to the quality and length of the electrical wiring in your house. These transmit over the power lines, and automatically negotiate speeds based on the signal quality. If you have long runs of wiring, naturally the quality will degrade over distance as this is using your internal copper wire.
It's perfectly suitable in nearly all circumstances though, and unless you have very bad wiring or a very electrically noisy appliance on the same ring main it will do what it says on the tin.
As for comparing to WiFi, that depends on what revision of WiFi you are using. Wireless AC is much faster, but again the signal still attenuates through walls, floors and the atmosphere and is of course just as susceptible to electromagnetic interference from other appliances etc.
For £20 these are great though.

Basically the use the internal wiring in your house to create a network.

However you normally have two rings in most houses, upstairs/downstairs for instance so you can get some connection problems at times if you have a powerline plugged in upstairs and your router/other connection is downstairs for instance.

All networks will deteriorate over distance so depends on the size of your house/flat etc, however you will find you won't even come close to the quoted speed. But you will probably still find them quicker than wireless.

I personally have never had any luck with the tp-links in my house, router downstairs, my pc upstairs, I always had frequent disconnections. However I moved to Edimax and no problems. But I expect as always different situations and setups will render different results.

apologies guys, thought this was a wifi unit. so this is wired connection only?

ok bud, keep your knickers on. the premises is the same except I made the mistake in thinking it was wireless as opposed to wired.

so how do these wired ones connect to the modem/router? do you attach one of the units to the modem/router and the other you plug in elsewhere to get the wired connection?

ive got devolo one which has wired and wifi built in. so the smaller unit plugs into the virgin superhub and the larger unit is placed upstairs to give the wifi signal and Ethernet connection.

Wired ones just connect with a standard network cable to the router. And then you have another powerline elsewhere for whatever you want to connect to it.

My setup is :
1 x Powerline connected to the router.
1 x Powerline connected to my PC
1 x Powerline connected to my sons xbox one
1 x Powerline connected to my daughters PC
1 x Powerline connected downstairs via a hub to the Sky box/Blu Ray/TV and Steam Link.

Recently bought another pair. Had the previous one last me 2 years and then suddenly decided not to switch on anymore. But these are great and good price, paid the same a few months ago.

I've had Powerlines for years, and got these a month ago.

In common with my previous units (a Belkin and a TRENDnet), they occasionally lose connection in my flat - random dropouts that will either fix themselves after a minute or two, or requires one or both units to be power cycled.

These dropped out two or 3 times a day. However, running a continuous ping in the background fixes the issue - no dropouts since I started the ping 3 weeks or so ago.

Good 'standard' price, just 40p more than I paid from Flubit last month...

Don't worry buddy, i knew what you meant :smiley:

Ah, so not much different to my devolo set up. One plugs with the router, and then the other units you can place where you want for the connection.

Much better for gaming and video streaming than wireless.

Quite the opposite - this is very much wired.
@dave_2245 it's like tunneling Ethernet network over PLC (power-line communication). You put one into the power socket next to your router (or core switch), second on the first floor (next to the place where you need Ethernet socket (uplink to your router/switch), then, say, third on the attic and fourth in the garage. Please do not put any filters/surge protectors between them - it might ruin the performance.
(please note: it's strongly advised to do initial setup/synchronisation beforehand)

Now after you connect Ethernet cable from your router/core switch to the first device, you "extend" this connection to the other connected powerline adapters - thus letting yourself to connect, say, IP camera in the garage or additional wifi AP in the office in the attic. Unfortunately those adapters do not "extend" wifi on their own.

Kind of like this:

I have explained this in post above (post 9).
It seems to be an issue with Qualcomm chips..

I have 5 of these. They are perfect. Unlike others these Work through extention leads too.

Not just Qualcomm chips - my Belkins used a Gigle chipset and suffered similar dropouts.

Irrelevant anyway as pinging fixes it.... but when I next upgrade I'll look out for Broadcom ones (will only need to upgrade the powerlines if I end up getting a new broadband connection which is faster than my current 76Meg fibre)

Any reason not to buy this model?
Has an extra port for only a few £ extra, or would it be better to buy the OP's model and a switch for extra ports?

I have these set up - x4 in total around the house. They are very reliable. No issues so far. The reason I went for TP-Link ones was that they use less electricity than the other models I compared them against.

I have 5 powerline adapters - but I prefer paying the extra to get a pass-through version so I don't waste a socket. The pass- through allow you to plug the powerline direct to the socket - then run a an extension cable from that with extra sockets.

PS - I have noticed that pass-through versions have become more expensive recently.

I have these, pretty good and reliable

Bought today, they work awesome. I was iffy at first but now I'm totally sold.
Simple plug one into your router and the other in another plug (into the wall) and boom. Buy now.
There are more expensive ones but unless your house is ridiculously massive then u have nothing to worry bout.

sorry if i sound thick but can these be used to save running a coax cable from my main arial on the roof that feeds tv in the living room to receive BBC ,ITV etc in my bedroom? also can they be used to get sky in bedroom ?

You made the mistake of posting your mistake on a forum,thereby giving it some credibilty to the less well informed.

so knickers,pants,thongs etc etc are entitled to be taken off,with complete fools like you around.

No

Sorry Ms perfect for making a genuine mistake. Oh sorry, you're a nobody on a shopping forum. I'm sure I won't lose any sleep over your comment. Jeez, guy makes a genuine mistake and people get high and mighty.

Yes, I have them, fantastic.

These work more or less identically to your 'wifi ones' - save for the fact that the WiFi ones, unsurprisingly, have an additional WiFi chip in one of the receivers. It then uses the 'wired' connection to supply network connectivity to the 'wireless' adapter inside the powerline.

These models do not provide wireless, but the wifi ones works in exactly the same way as if you had plugged a WAP in to the Ethernet port of one of the receivers on this model (but you get an extra Ethernet port :smiley: )

Are these any less safer to use if plugged into an extension lead?

Better add £3 and get them with double ports:
TP-LINK 500Mbps Powerline with 2x Ethernet Ports.

They have to be plugged directly in to the mains socket as extension leads add some sort of an interference.

EDIT: You can get the ones with a pass through if there isn't a spare socket available and then plug your extension lead into that.

​I seem to be experiencing the same brief random dropouts with mine (but they're great otherwise). Could you explain how to run a continuous ping?

I had the same problem until I created a .bat file in notepad to ping the router constantly. To do this open notepad and type (without quotations) "ping xxx.xxx.xxx.xxx -t" and replace the x's with your router IP address. Then click save as and click all files and call it "ping.bat".
Then to run this you will need to right click run as administrator.
To save the hassle of opening ping.bat each day I created a task scheduler to start ping.bat with administrator privileges whenever I turn my PC on. I hope this helps!

​Cheers for that! Both useful and educational. I didn't realise making .bat files was so easy. Haven't touched one since hacking autoexec.bat on a 386 back in the day to get X-wing to work!
