Finally, my ethernet card works. When I have setting my network card (manually, one month ago) I have set gateway at the same IP of machine that contain it. --------------- To solve I have removed card. At boot kudzu have found a new hardware and ask me to set static IP. On mask kudzu propose me to set 192.168.0.254 for gateway. After my confirmation, my card result correctly installed. Works ping and resolve your IP. Thanks fedora-list !! bye by fellons
