1.) This is a German speaking NewsGroup.
You might probably be better off when asking in one of the
*international* (English-speaking) NGs in the
microsoft.public.windows.vista.-hierarchy.
2.) When asking questions, pls do this in a way providing enough
information on what you are asking for.
Asking in the "subject" only, generally is not sufficient.
Your posting is a fine example for leaving everyone in the dark.
AFAICS no one in the the MS newsgroups has taken any classes in
clairvoyance. And therefore no one will be able to see which kind of
problems your router might produce.
