>Is it eth0 or eth1? Sure you're not getting ports confused? ethtool -p
I confirm you it is ethtool eth0 output, I'm quite busy today i didn't check in details the copy/paste.
As I said to Quinn Fissler, my internet connection maximum speed is 100mbps so it might prevent the nic to set itself to 1000mbps i'll get a 1000mbps switch and test the nic in a tiny lan this week end. Thanks for your answer.
