after the last update the driver is lost. I have tried hard (several nights) to get it running. Now with the last update it's gone. Any thoughts why this is not supported natively? What is the best way to get it back?

please press Ctrl-Alt-t, in the terminal, run: lspci -vv | grep Atheros, edit your question and post output of that command. Also: Do you have internet access through wifi? – phipsalabim Feb 19 '13 at 19:48

Open terminal and run:

sudo apt-get install linux-backports-modules-cw-3.4-precise-generic


sudo modprobe alx

I hope you have internet access through wifi.

I had the same issue but when I installed 12.04.2 from disk, the Atheros 8161 ethernet card was not working due to the alx driver missing.

I did the following to get it to work:

  1. apt-get update
  2. apt-get upgrade

    The following packages have been kept back:

    linux-image-3.5.0-27-generic linux-headers-3.5.0-27-generic

  3. sudo aptitude

If you have kept back package you should see Upgradable Packages on top of the list.
