This wasn't obvious for me! Thanks for the answer!

When I set the media by hand it showed 'active', but no data could be transmitted 
(yellow link diode on switch, not blinking). I then pulled the switch with my home 
lan from the wall and plugged my re0 instead - It worked! 

So this seems to be the %$R#(@%*$ switch issue. The funny thing is, that with media 
set manually (or sometimes with autoselect) everything works fine with this switch 
(i have used it all day yesterday till evening without problem). Now, when i wait 
some time with media manually set, it starts transmitting data and everything works fine. 
Why does it happen? Why is it so unpredictible? Can it be fixed in software, 
or should i throw the switch out the window and by a new one?

Thanks and best regards,
