17.1 Legacy Series / Re: WAN link gone sometimes (igb driver, I211 nics), only ifconfig down/up fixes it

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





Sincely
