What is Powerline Adapter? And Which One is Best for You?

Ever wonder how lamp poles are turned on at night, and then turned off again?

I don’t either. But what is interesting is that lampposts use the same technology that homeplugs use for internet via the wall socket or powerline adapters!

What is powerline adapter? How does wifi via power outlet work, what are the disadvantages and when internet via power does NOT work? We will cover all of this in this article.

The technology is called: “Power Line Communication” This is what you want in your home if you don’t feel like pulling cables.

How does Powerline Adapter work via Electricity?

The homeplug adapters are very easy to use. They can be used in all sockets in the house and usually come in sets of 2. The idea is that you plug one powerline adapter into the socket next to the router/modem and connect it to an ethernet cable. The second adapter can be placed somewhere in the house where wifi is needed.

So it’s quite straightforward:

  • Plug one adapter into the power outlet near the router/modem
  • Connect the adapter to the router/modem using an Ethernet cable
  • Place the other adapter somewhere in the house where you want internet via electricity!

Please note that the homeplug you bought also has a built-in wifi access point. This way you no longer have to buy an extra wifi router or access point where ever you want wireless internet in your house. Below we will guide you on which powerline adapter is best for your house.

If you have no need for Wifi and you only want wired internet via a wall socket? In that case, this option is for you.
Keep in mind that you have to connect an access point if you want WiFi. This is useful if you want to connect a printer or an IP internet camera. 

Wifi via power outlet, why can’t you see it everywhere? Does it have drawbacks?

This is because the powerline adapters in large buildings with a lot of electricity groupings may not work properly. This can also be the case in buildings with special electricity cabling. 

We therefore recommend that powerline adapters should only be plugged into one electricity group. If it doesn’t work, fortunately you are always protected as a consumer on Amazon and you can return the adapters within 14 days. 


We hope that this article could help you understand what is powerline adapter and how powerline connection works.
