The manual is a joke. You beschrÃ'nkt to uncommented pictures illustrate the installation. Except the guarantee notice there is no word text, no further evidence, no "Troubleshooting" tips. Perhaps there is indeed a solution fÃ'r the problem, but here I am in the rain fÃ'hle left.
Update 3/25/2015:
Although the sole installation of adapter did not work on our network, we succeeded in the GerÃ'te a spÃ'ter constructed network
to integrate in adapters of the type Devolo 1200+. They were equal to automatically recognized when plugged into the electrical outlet and operated easily without any other adjustments.
