The Phansenkoppler unfortunately conceded no improvement in my AVM 500 Powerlan adapters. My best adapter runs on the same stage with about 200 MBit moment during my worst in a second phase with around 90MBit runs. The phase had no effect on network performance. Unfortunately, I have found neither at AVM still at Kemo information about the used frequency range. That would, however, to know whether the two ever work together important information.
