I went home unsuccesful and then returned today, two days after I fought with this, because I had some ideas I wanted to try. So I booted the system and -whoa- worked perfectly without a change. I don't know what kind of router we have but it obviously keeps ARP values cached too long. I'm a bit happy though, as the problem turned out to be exactly what I had expected the whole time. But one question remains: I changed Ethernet cards in a workstation earlier the same say, and at that time I could access the net right away. Why did it go so fast that time? Why did I have to wait many hours when working on the laptop? What was the difference? I don't expect you to know these answers :) as I don't know anything about our router. But it's interesting to notice that this timeout obviously is *very* random. Unless there is some sort of "inverse" ARP which lets the workstation broadcast that "I am xx.xx.xx.xx with MAC xx:xx:xx:xx...". > You can't force the router to forget.
