After I was cut off from the Internet, I desperately needed a new power supply for my Speedport. At the Telekom I did not get the help that I would have needed. I was offered only a new Speedport with PSU. So I researched on the Internet at a friend arrived and so on this article.
The power supply was gelifert overnight. It is exactly the right product. So I can surf the Internet without interference again.
Thank you to the dealer for the fast delivery and uncomplicated handling.
