I spent quite some time on the phone with Telekom and finially I had someone on the other end and sounded like he knows what he is talking about. Pretty easy, no new speedport just switch one button form ext. to int. - then the whole internet problem was gone. The next question is who switched the button??? I didnt do it and the Internet worked fine the one day and the next day I couldnt get online any more....... hmmm do I have a ghost in the house??? I will watch out and see if I have more inexplainable occurrences in my house.
