Fresh install XUbuntu 12.04. After boot network interface is down. After unplugging and plugging back network cable, network is up and running again. Later (randomly) it may go off again. Again, unplugging and plugging back network cable helps.

Ethernet card is onboard Intel.
Mainboard: FUJITSU D3076-S1

Same problem happens with onboard ethernet with Intel mainboard DH61BE.

I have to buy and insert TP-LINK TG-3468 ethernet card (Realtek chipset). They work without problem.
