For months we had massive problems with our WLAN in the house. The wireless router is with us on the top floor and the ground floor, I had a repeater. Unfortunately, the signals from the attic came downstairs because our concrete ceilings not feel right and there have always been communicating holes or complete terminations.
Since I have installed the AVM FRITZ! Powerline, everything works fine !!! Finally wireless interference throughout the house.
The device functioned relatively easy according to instructions. The configuration options are fine and you realize that is mature software and technology. For weeks no problems in daily use.
