First time Ubuntu user and already having an issue! My ethernet is no longer working (showing *-network UNCLAIMED). Wonder if anybody can help. Outputs are as below.

sudo lshw - C net:

    *-network UNCLAIMED
    description: Ethernet controller

lspci -knn | grep Eth -A3; uname -a:

dmesg | grep e100:

sudo modprobe e1000e:

no output

To be honest, I'm not sure what else I could pull that would help. The device is also stand-alone which i'm sure doesn't help.

Thanks!

    Please edit your question and add output of lspci -knn | grep Eth -A3; uname -a terminal command. Does "no longer working" means it used to work before? – Pilot6 Aug 13 '17 at 18:59
  • @Pilot6 Updated with additional ouput. It was working the first time I unstalled Ubuntu 16.04 on this. Then after I shut it down and restart it after all my updates, it stopped connecting to the internet. After that, I reinstalled ubuntu hoping it would solve the issue but no good. – gerbilz Aug 13 '17 at 19:43

    Please edit your question to add the result of the terminal command: dmesg | grep e100 – chili555 Aug 13 '17 at 19:46
  • And also sudo modprobe e1000e – Pilot6 Aug 13 '17 at 20:16
  • This is a kernel bug. I suggest testing the 4.10 kernel. If you are using Ubuntu 16.04, run sudo apt install linux-generic-hwe-16.04 and reboot. – Pilot6 Aug 13 '17 at 21:05

To just help you onto the next step in trying a newer kernel.

You can download the needed packages from multiple places and in multiple ways. One way you could get them is to download them from packages.ubuntu.com You will need this 3 packages for kernel 4.10.0-30-generic:

  • You forgot linux-image-extra. – Pilot6 Aug 13 '17 at 22:11
  • I left it out on purpose, however it will not hurt, but could be marked as optional with a reference to askubuntu.com/questions/153023/… – Anders F. U. Kiær Aug 13 '17 at 22:13

    Network drivers are there. It is useless without the extra. The accepted answer is obsolete. – Pilot6 Aug 13 '17 at 22:14
  • Ok, then we let is stand like that, i have not looked into which exact modules that is excluded from the generic package :) – Anders F. U. Kiær Aug 13 '17 at 22:17
  • Downloaded all 4. Am going to try my best to execute them. thanks all – gerbilz Aug 13 '17 at 22:25
