"I had an similar Problem with
an another NIC on a embedded Device.
.. it can be possible, the Power Management
/Energy Saver Mode of your Intel NIC works not correctly.
Disable for the i211 GB Nic:
* the Energy Efficient Ethernet Saver Mode
* and WOL (WakeOnLan) for this Interface.
Test it manually with ethtool ...
Use:
Disable Energy-Efficient Ethernet Mode:
ethtool --set-eee <your nic device> eee off
Disable WakeOnLan:
ethtool --s <your nic device> wol d
If it works ,
put the modifications to load @ boot
in
/etc/rc.local
