P9x79 WS-E Network not working

Hi there,

I have mountain Lion Installed and booting, everything works fine ( sound, video) BUT I'm unable to have one of the onboard Ethernet connexion up and running.

Tried the AppleIntelIE1000e.kext without success.

The spec said LAN: 2 x Intel i210 Gibabit LAN controller..

Thanks
Thierry
