I have the problem that the ethernet device on the Intel NUC is not found.
ifconfig -a only shows lo and wlan0 but not eth0.
sudo lshw -C net gives the following output:
*-network UNCLAIMED description: Ethernet controller product: Ethernet Connection (3) I218-V vendor: Intel Corporation physical id: 19 bus info: pci@0000:00:19.0 version: 03 width: 32 bits clock: 33MHz capabilities: cap_list configuration: latency=0 memory:f7100000-f711ffff memory:f713b000-f713bfff ioport: f080(size=32)
sudo lshw -C net and
dmesg | grep -e eth -e e1000, I get this output:

Product information (
lspci -nnk) is the following:
00:19.0 Ethernet controller : Intel Corporation Ethernet Connection (3) I218-V [8086:15a3] (rev 03) Subsystem: Intel Corporation Device [8086:2057]
Kernel version is 3.19.0-22. I am booting in UEFI mode. The BIOS version is the latest version.
As suggested, I updated the BIOS to the newest version, Left the device without power for a while and changed the hardware configuration. So far without luck!
I just installed Windows, and the device also isn't working there. This probably means that it's either a BIOS problem, as suggested, or the hardware is actually damaged.
Any further thoughts on this?
For others with similar problems:
In the beginning I thought this was a driver issue. I wanted to install the newest version of the e1000e driver. This requires version 8.x.x of the e1000 driver. When I tried to install this driver, I got the following error message (even though I run kernel version 3.19):
*** Aborting the build. *** This driver is not supported on kernel versions older than 2.4.0. Stop.
However, it turns out that the old driver on the system was working fine. The real problem has to lay somewhere else.
