Yesterday I was having problems with Lubuntu 14.04 updates machine I had to follow this check-marked answer Not enough free disk space when upgrading

The answer worked well but Today when I turned on my computer I could not connect to any network (either wifi or ethernet) they are just not showing up. Furthermore After running: sudo lshw -C network -numeric I get

*-network UNCLAIMED

As you can see both networks appear unclaimed, which from what I've read makes me suspect that is a drivers problem. Is there anyway to get this working back again without having to do a clean re-install. I just do not want set up all my dev environment from scratch.

EDIT

After dpkg -l | grep linux-image

uname -r

  • Do they reappear if you simply load the drivers? sudo modprobe ath9k && sudo modprobe r8169. Any errors? – chili555 Feb 11 '15 at 20:10
  • I get FATAL: "Module ath9k not found" Same for the other. – La Murga Feb 11 '15 at 20:40
  • Can you reboot into an earlier kernel at the GRUB menu? Perhaps we can reinstall your current linux-image. I hope you kept an older version as posted in the answer you linked. – chili555 Feb 11 '15 at 20:45
  • Yes I did, I am going to post the result of dpkg -l | grep linux-image and my current image on the question. I am not quite sure how to work with the GRUB though. – La Murga Feb 11 '15 at 20:53
  • help.ubuntu.com/community/Grub2 Please see here about getting to the grub menu. We also need to know the version for which the drivers seem to have disappeared: uname -r Thanks. – chili555 Feb 11 '15 at 21:41

I suggest you reboot into an earlier linux-image by selecting it at the GRUB menu as I linked above. Afterwards, reinstall the faulty version:

sudo apt-get install --reinstall linux-image-3.13.0-45-generic

When finished, reboot and test.

  • Yes so I booted from the .40 version and I got my internet back on!. Thank you so much! – La Murga Feb 11 '15 at 22:18

    Awesome! Glad it's working. – chili555 Feb 11 '15 at 22:22

    chili555 at it again... I think I'll just remove networking from my feed! ;-) – Fabby Feb 15 '15 at 15:06
