I have an old house with a grid again fifteen years. I had already used PLC adapters older generation and was very disappointed flows. At 10 meters the signal was already unusable. Threw very skeptical. Here, it is perfect in any home, on any outlet, the signal is effective. Even the 2nd floor and garage located one block away from the house. I associated it with a dLAN 500 WiFi + duo dLAN 500 of the same brand. There were no problems, easy and fast setup.
Also this dLAN 500 WiFi can be turned off easily and even programmed via its web interface to activate the wifi at certain times. Very handy in a room when that one does not wish to be bathed by wifi waves all night. I am very satisfied with this brand.
