I was excited by this package when I set up. The installation of this network was relatively simple because I have carefully followed the instructions in the manual. The software "Devolo dLAN Cockpit" is simple and effective, configuration and complete control of the network from your computer is easy. The PLC system is not always very good as some but worked well for me in accordance with the manufacturer's recommendations, ie have outlets only dedicated adapters for maximum efficiency. The interest here is that each transmitter has wifi but unfortunately this system has become defective after some time. I have now reactivated the wifi on my livebox adapters because it disrupted my entire home network. The Fast Ethernet port is still operational and provides great data traffic speed and I have no blockages in the movies in high definition. In summary, today, I deleted one of the adapters that are no longer useless because it was dedicated to the wifi and I turned off the wifi system.
