The Fritz Powerline 540E fulfilled its function in the rough, but that depends in which one socket, install the powerline adapters in the home. There is the further the more problems. Briefly, the LAN connection over the power lines is unstable. The LAN network constantly breaks together to total loss of communication. To reconnect you have to pull the Powerline adapter from the electrical outlet and then plug it back. Is in this way again to connect to the contrary, a powerline adapter connected to the router, built. The cause of these failures are multiple sources of interference in the house. Two of the sources of interference are now known to me. Once there is a halogen lamp, whose transformer (220V> 12V) is probably the source of interference. Turning the lamp interrupted not entirely connect to the router but the internet signal was not available. When you turn off the lamp, everything was fine, the internet signal was back fully. The second source of interference, the LED ceiling lights that are located in the same room with the Powerline adapters. The on / off of these lamps had the same effect on the Powerline LAN network, as described above. The Powerline LAN network, via the power lines only work who no transformers or electronic power supplies are connected to the lines. Possible create the sockets with special filters also remedy this experiment should be done to find out.
