Hehehe. The first thing the "KDE expert" does is post a question.

I have used konqueror and kget for downloading stuff for years now. It always worked fine with my dialup connection. My shiny new ADSL modem arrived yesterday and kget doesn't download anything. If I use wget on the commandline for the very same URL, it works. Same with Firefox. Just kget doesn't like my new ADSL connection.
Weird. Weird. Weird.
