Hi,

I seem to have a problem, with my internet connection when I am logged in Linux. Shortly...I have no problem with the internet connection when I am in Windows. When I boot in Linux (Knoppix installed on the hard)...I can browse only with the konqueror. Firefox won't open any page until konqueror did it. Also I can't connect to update any packages (apt-get update), and also can't use any other programs who use the internet (chat, irc, mail...etc)
I changed the ethernet card, the problem persist. I am connected to the internt through a router (communication between router and computer is ok ...on linux and windows as well)...Have anyoane an idea why this happens?

Kindest regards.
