When I plug in a network cable, it is not recognized. The WI-FI is working properly, though.

ifconfig output:

  • try dhclient eth0 and see if it works.

  • what about ifconfig -a. Do you see something like eth0 of eth1 or something similar.

In my case (Ubuntu 12.10 with Inspiron 14z), just installing the linux-backports-modules-cw-3.6-quantal-generic package solved the problem. Here's the magic command:

sudo apt-get install linux-backports-modules-cw-3.6-quantal-generic

p.s.: This seems to be a duplicate of: 12.04 does not detect eth0(Atheros AR8162 )

  • I tried to install the package above but got the following message: E: Unable to locate package linux-backports-modules-cw-3.6-quantal-generic E: Couldn't find any package by regex 'linux-backports-modules-cw-3.6-quantal-generic'

Download the drivers from this website: http://linuxwireless.org/download/compat-wireless-2.6/.

If you're not sure which one to select, download this one: http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-2012-09-05-pc.tar.bz2.

First run sudo su and enter your password when prompted.

Then, follow these steps:

tar xjf compat-wireless-2012-09-05-pc.tar.bz2
cd compat-wireless-2012-09-05-pc
./scripts/driver-select alx
make
make install
modprobe alx

Reboot.

It might seem misleading to download the drivers because of the name, but give it a shot.

  • I will love to change the negative into an upvote if it works to the OP or if you give some reference or explanation about how does it work and why. Sep 6, 2012 at 18:18
  • It worked!!! Just a note to someone following this thread: I had a permission problem, so remember to 'sudo'. Thank you @green7.

  • Please accept the answer if you find it as correct. And also please tell where did you use sudo so that I can correct it.

  • The first time it did not work, if I remember well, it had a permission problem in ./scripts/driver-select alx. So I used "sudo su" and did the entire process again...
