Note A thin, stick stuck in the Fritz box.
Programing has worked for me under Unitymedia 4 weeks.
Then I was able to install it
Devolo 40,000
T-Link 36 000
and now
AVM 86 000
of 100 0000 assured of Unitymedia, ie faster than Devolo 500 via the electricity network.
Why not get any easier?
Therefore, 4 points.
