Frequently Asked Questions: Powerline Adapter

What is a powerline adapter and how does it work?

With a powerline adapter you can easily connect your router to a computer or two PCs.

The WLAN signal can also be expanded in this way. So that means you can bring fast internet to every room in your house or apartment with these adapters. The adapters set up a local network.

The adapters are often also called Powerline Communication or PowerLAN. The adapters transform data from the Internet or from a PC into high-frequency signals.

They then send these to the desired destination via the power grid. According to the manufacturer, the range is up to several hundred meters.

The purpose of such a device is to exchange data and improve the surfing experience. The WLAN connection is strengthened with the help of integrated “WLAN access points”.

To do this, the adapters initially work via the power grid, thus expanding the Internet access. It then distributes the WLAN signal using a radio link.

Are there different types of powerline adapters?

Powerline adapters differ in their data transfer rates, their design and the number of LAN connections.

  • Data Transfer Rate
    • Mbit / s
  • Design
    • With or without an integrated socket
  • LAN connections
    • Amount

Data Transfer Rate

The fastest on the market manage around 1200 Mbits per second. Standard devices, so-called HomePlugs, transmit data at a rate of 500 – 600Mbit / s. They have a range of about 300 m.

Old devices only manage 200 Mbit / s. These are not recommended because, in addition to their low data transfer rate, they can also be influenced by disturbances in the power grid and thus work even more slowly. In these cases, the internet isn’t even enough for a YouTube video.

However, it should be noted that the manufacturer’s information only relates to short distances. The further away the target, the lower the rate of data transfer.


The adapters can also be distinguished by their design. You can get a device with or without an integrated socket. With an integrated socket you don’t lose a slot, which can be a plus point.

LAN Connections

In addition, the Powerline adapters can be distinguished by how many LAN connections are available. With the help of these connections you can integrate your devices (PC, consoles, TV, etc.) in a stable manner in the network.

What are the advantages of a powerline adapter?

The advantage of a Powerline adapter is that you can have internet access everywhere, even in houses with thick walls. So to do this, you don’t have to chisel open your walls and run network cables in them.

With powerline adapters, you can quickly surf the World Wide Web in every corner of your house for little money and effort.

  • Strong internet connection throughout the house
  • Lower expense
  • Low cost
  • Safer than WiFi
  • Expandable as required

In addition, the data that is sent using a powerline adapter is better protected than in WLAN. To get to the data, the hacker would have to be in your circuit. The data is also encrypted.

To be on the safe side, you should definitely change the password that you received from the manufacturer. Once you have bought an adapter and thus set up a home network, you can expand it with any number of adapters.

How do I install a powerline adapter?

To set up your local network, you plug the first adapter into a socket near your router. You connect these two with a network cable.

If you want to set up your network or buy an adapter for the first time, then you need a starter kit. If you want to expand your network, a simpler connector is sufficient.

Then you place the other adapters where you want to have internet access. Then you press the “Sync button” to connect the adapters to each other.

Types of Powerline Adapter

Basically, you can distinguish between three connection options thanks to the powerline adapter:

  • LAN powerline adapter
  • WiFi powerline adapter
  • D-LAN powerline adapters

Due to the different areas of application and your own preferences, a certain powerline adapter is best suited for you and your needs.

Because of this and the fact that not every type of Powerline adapter is the same, there are different advantages and disadvantages in use.

We would therefore like to introduce you to the different types in the following section and help you find out which Powerline adapter is right for you.

For this purpose, we will introduce you to the above types in more detail and clearly show what their advantages and disadvantages are.

LAN Powerline Adapter: Advantages & Disadvantages

The first type of Powerline adapter that we would like to introduce to you in this comparison works with a LAN connection.

With the Local Area Network, or LAN for short, a computer or notebook is connected directly to the LAN cable so that an Internet connection can be used. Most computers have corresponding LAN cable inputs.

This Ethernet connection can achieve a performance of up to 100 Gbit / s, which can ensure extremely fast loading times for videos and websites, if your internet contract fits.

Thanks to the internet connection of a LAN powerline adapter, you can watch films or videos on your computer particularly well.


  • Better performance for your device than with WiFi
  • Better to watch movies and videos
  • Trouble-free internet connection


  • Risk of tangled cables
  • Internet connection limited to one device

The connection via LAN is usually free from interference and the performance is higher than with a WLAN signal. However, the cables can be annoying and create a certain tangle of cables that can annoy you both visually and practically.

Even if you need a powerline adapter to amplify the WiFi signal in different rooms, you are better off using a WiFi powerline adapter.

WiFi Powerline Adapter: Advantages & Disadvantages

The second type of powerline adapter is the WLAN powerline adapter, which can amplify or generate a WiFi connection.

Here, the data is transmitted wirelessly without tangled cables. The devices can be used from anywhere and use is not limited to a single device.

However, the problem is that walls or large objects standing in the way can affect the signal quality. Such a WLAN powerline adapter or repeater usually helps.

You can usually plug this into the socket to increase the signal strength and increase the range. This allows you to use your devices further away from the router.


  • Internet connection without tangled cables
  • Several devices can use the Internet connection at the same time
  • Access the network from anywhere in your home


  • Walls or large objects interfere with the signal
  • The network bandwidth is restricted by a repeater
  • Internet connection suffers when using multiple devices at the same time

However, such a repeater restricts the bandwidth of your WiFi network, which makes it more difficult to use multiple devices at the same time.

However, if a device can be useful in your home so that you can increase and strengthen the range of your WiFi network, you should buy a WiFi powerline adapter.

D-LAN Powerline Adapter: Advantages & Disadvantages

The last powerline adapter is the so-called D-LAN powerline adapter, which can send the data via the power grid through walls and ceilings.

Such a set usually contains two adapters, a transmitter and a receiver. With this you can generate a bandwidth of up to 600.

If you can use such an adapter for a very large building, you can also choose a set that contains several adapters that you can distribute around the building. This allows you to generate a good internet signal in many rooms via the powerline adapter.


  • Very good for larger buildings
  • No signal interference from walls
  • Adapter can be expanded as required
  • Simple and straightforward installation


  • More expensive than other powerline adapters
  • Increased power consumption

We recommend products that achieve a transfer rate of 500 Mbit to 1.2 gigabits per second. The installation of these adapters is also very uncomplicated and quick.

However, such adapters are more expensive than others and use up your power supply significantly more than normal powerline adapters.

Powerline Adapter: Purchase Criteria

Essentially, when buying an adapter, you should pay attention to the following points:

  • Data Rate / Version
  • Manufacturer
  • WiFi Access Point
  • Connections
  • Design
  • Range
  • Power Line

Data Rate / Version

In general it can be said: the newer the version, the higher the data transfer rate. For better results and faster internet access, you should look for a high rate.

Which rate you choose depends on your usage behavior. If you only want to enable Internet surfing with the adapters, 500 mbit / s is sufficient.

However, if you buy an adapter to stream films and series or to play games online with your friends, then you should consider a device with 1,200 mbit / s.


When expanding your local network, make sure that you are using the same manufacturer.

In theory, you can also use adapters from different brands or with different data transfer rates together.

Most of the time, however, this leads to problems and disruption of the connection. We recommend that you use adapters from the same manufacturer and from the same product series in order to achieve the best result.

WiFi Access Point

If you don’t just want to connect floor-standing devices such as PCs or TVs to the local network, make sure that the device has a WiFi access point. You can also integrate smartphones, tablets and laptops into the network.


Make absolutely sure that the LAN connections are Gigabit LAN interfaces. Only in this way can the adapter really achieve its data transfer rate.

If you buy an adapter with several LAN connections, you save yourself additional adapters in this room.

So think about beforehand which devices you would like to connect to the network in this room.


The design of your adapter can have advantages. We generally recommend a device with an integrated socket.

This way, your new adapter doesn’t occupy a socket that you could possibly need. If you want to buy an adapter for an angled corner, we recommend a model with a slim and space-saving design.


You have to select the range depending on the use. Most manufacturers advertise a range of 300 m, which should be sufficient for almost all houses and apartments. So think about how far the network should go and buy your adapter accordingly.

Power Line

Check your power lines before buying a powerline adapter.

This will tell you if you need to take any additional precautions. On the one hand, the adapters work best with modern power lines.

You should also check to see if your home has one or more electrical circuits. If you have several, then ask an electrician to install a phase coupler so that the powerline adapters can exploit their potential.

Electricity meters between point A and B interfere with the transmission enormously. So if there is such a counter between your endpoints, an adapter makes little sense.
