network UNCLAIMED (Intel I219-V) Ubuntu 18.04.1 LTS

Question

After Ubuntu updated to 18.04.1 my wired network does not work anymore.

ifconfig -a

I downloaded a driver from intel but could not install it

allan@allan-MS-7998:~/Dokumenter/ethernetdriver/e1000e-3.4.0.2/src$ sudo make install

/bin/sh: 1: [: -ge: unexpected operator
Makefile:199: *** *** Aborting the build. *** This driver is not supported on kernel versions older than 2.4.0.  Stop.

Can anybody help me to activate my wired network again please?

sudo modprobe e1000e && dmesg | grep e100

Here are some more info:

I was able to install the new driver. But as chili555 said, there must be an underlying problem that should be solved:

dmesg | grep e100

What does the last line mean? I have searched the net without finding anything I could use.

If the driver already present in the kernel, e1000e, is not working as expected, something else is wrong. Installing a different driver will likely not help as the underlying issue is still not fixed. Please edit your question to add the result of the terminal command: sudo modprobe e1000e && dmesg | grep e100 — chili555, Aug 19 '18 at 18:11
I read this post, https://askubuntu.com/questions/945917/intel-ethernet-not-working-network-unclaimed/945954 but although it looks like the same issue, it's another version of kernel and OS. My Kernel is 4.15.0-32-generic x86_64 — Allan Bertelsen, Aug 20 '18 at 06:32
I just updated the BIOS, but it did not change anything. Now BIOS in inxi is: UEFI [Legacy]: American Megatrends v: 1.E0 date: 06/15/2018 — Allan Bertelsen, Aug 20 '18 at 09:36
I booted on a live usb with Ubuntu 14.04.4 LTS. It had the same issue. Is it possible that the hardware is broken? — Allan Bertelsen, Aug 20 '18 at 12:23
It is possible but I think there are things we can check first. Is this a dual boot with Windows? Is the result the same if you cold boot to Ubuntu rather than reboot? Does the device work in Windows, if this is a dual boot? Are there settings in the BIOS that deal with interrupts? Is this an integrated card or removable? is it seated properly in the slot? — chili555, Aug 20 '18 at 14:10
Thanks chili555, It is not a dual boot configuration and it is integrated in the motherboard. I did not want to use more time on this issue, I found Ethernet-card to replace the build in card and disabled the old one in BIOS. Normally a live cd/usb would connect without any problems. Having a spare card laying around saves me further agonies. — Allan Bertelsen, Aug 21 '18 at 06:31

This is the solution that worked for me. Ethernet controller I219-V is integrated into the Z170A SLI PLUS motherboard. Updating the BIOS and booting to an operating system that previously worked - without any luck - convinced me that more work on this issue would be a waste of time. The solution was to disable I219-V in BIOS and install a new network adapter. For those who might have a similar problem that they would still try to solve, I apologize. But a new card is so cheap that it does not pay to go on.
