Support / FAQ

Can Wi-Fi be used simultaneously with the integrated LAN port?

Yes, Wi-Fi can be used simultaneously with the LAN port.

Which Wi-Fi-capable devices can I connect to dLAN® WiFi adapters?

You can connect any current mobile device with a Wi-Fi module to dLAN® WiFi adapters - giving you a fast wireless connection to the Internet and your home network. This includes smartphones such as the Samsung Galaxy or Apple iPhone, tablet PCs such as the Apple iPad and notebooks. You can also network appropriately equipped consumer electronics in no time - such as a Smart TV or Internet radio.

What are the prerequisites for using dLAN®? Where are the limits?

dLAN® works throughout the entire mains supply network of the house or apartment, regardless of whether the building is old or new. Of course, the network has to be on the same wiring, and the wire length must not exceed 300 meters. However, different phases are not a problem. Power meters attenuate the signal strongly, but do not necessarily block it.

Can I use devolo products even if I have different electrical circuits in my house?

Yes, devolo products also work if you have multiple circuits (phases) in the house. You do not have to modify the mains supply, such as by installing a phase coupler.

Can I also use devolo products in power strips?

In a few cases, power strips - particularly those with integrated switch and surge protection - can impair performance. To attain optimal connections, we recommend using devolo products with integrated (pass-thru) electrical socket and plugging the power strip into the devolo adapter.

Are dLAN adapters of different speed classes (200, 500, 650, 1200) compatible?

Yes, dLAN products of different speed classes are fully compatible with each other.

The only exception here is old devices with a speed of 14 and 85 Mbps. Unfortunately, these are not compatible with current products.

For technical reasons, devices from the devolo Magic series are not compatible with dLAN devices.


In a mixed network, each adapter connects to every other adapter at the highest possible speed. It does so independently of the other adapters in the network. In a network consisting of a 500 Mbps adapter and two 1200 Mbps adapters, for example, the 500 Mbps adapter will connect to the 1200 Mbps adapters at a speed of 500 Mbps. At the same time, the 1200 Mbps adapters connect to each other at the full 1200 Mbps.
