@MGebhart: I did already apply all things you mention, and already got it fixed. Thanks anyway! I also made some 'knees' with some ferns attached. An update will come soon as soon as I have figured out how to gain access to the internet again on my main pc. It is acting weirdly (pinging ip works, there is information going up and down, but IE, Opera, Outlook etc. cannot get access, and I have erratic scroll behavior in explorer, text editors and such.) I suspect a virus, and probably have to install all from nix.
