Is this powerline kit right for me?
This powerline socket provides you with an internet connection directly from the electrical socket, while ensuring the plug in use doesn’t go to waste with its pass-through socket. Through the use of Devolo’s range+ technology, all three wires in the electrical circuit are used to provide transfer speeds of up to 500Mbps between the plugs. The plug is equipped with two LAN ports, which you can use to plug your games console, media player or smart TV to your network, without the need of a long Ethernet cable or complicated wiring.

How could I use this powerline kit?
The Devolo dLAN 550 duo+ is plug and play, which makes installation simple and quick. Plug the socket into the mains, press the link button and within two minutes this new plug will be part of your existing system. The plug is also HomePlug certified, making it compatible with other manufacturer’s HomePlug certified devices. All you need to do is use the same password on all the powerline adapters to create a common network.

How does powerline work?
Powerline technology transfers data using the electrical wiring of the household. A single powerline plug is connected directly to a router and plugged into a mains socket. This plug then communicates to all others on the same electricity supply. This kit comes with a single powerline plug that connects to a router, and another plug that will connect to your networked device and allow it to communicate with your router over the mains. The powerline adapters will communicate with each other when connected directly to mains sockets on the same fuse board. Additional receivers, including receivers that give a wireless signal, are sold separately and can connect additional devices to your router. For the best results, choose a powerline receiver capable of sending up to 500Mbps.
