Ethernet not working on a Dell Inspiron 14z

Question

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

ifconfig output:

          inet addr:127.0.0.1  Mask:255.0.0.0

what about ifconfig -a. Do you see something like eth0 of eth1 or something similar. — green, Sep 05 '12 at 19:28
ifconfig -a shows the same info, no eth0 or eth1. I will log in to be able to chat. — Izabela, Sep 05 '12 at 20:07
Run lspci | grep Ethernet. If you don't see anything, run lspci and look for anything that seems like ethernet card. Or better post the output. — green, Sep 05 '12 at 20:30

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' – Izabela Dec 26 '12 at 15:00

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. – Javier Rivera Sep 06 '12 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. – green Sep 10 '12 at 11:21
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... – Izabela Sep 11 '12 at 02:06
I'll update the answer. :) – green Sep 11 '12 at 08:15
