[Solved] Wired Connection(eth0) not detected in Ubuntu 12.04

Networking

Some of the latest Laptops especially Dell Inspiron 5420 and Lenovo G580 series comes with Atheros Network driver which has some problem with Ubuntu 12.04. The problem is that it will not detect the wired network connection(eth0) even though wireless connection is working fine. We can solve this issue by installing the proper network driver.

First you have to download the latest driver from here http://linuxwireless.org/download/compat-wireless-2.6/

Open Terminal (Alt+Ctrl+T) and extract the downloaded file using following command.

tar -xvf compat-wireless-2012-07-03-p.tar.bz2

Copy and paste the following commands one by one to change the working directory and install the driver

cd compat-wireless-2012-07-03-p
scripts/driver-select alx
make
sudo make install
sudo modprobe alx

Done... Now you should be able to connect to the Internet using wired network.

Thanks for all comments, now my wired eth0 is working. Just let me upgrade comments above:
I have downloaded "-pc" driver not "-p" driver (the last one is not working) and later follow these steps:
tar -xvf compat-wireless-2012-07-03-pc.tar.bz2
cd compat-wireless-2012-07-03-p
scripts/driver-select alx
sudo make
sudo make install
sudo modprobe alx

Hello! I'm a beginning user of linux (ubuntu 12.04. LTS). I have the same problem with my wired connetion. I have just try to follow your tips, but I don't know how to install the driver from the site you indicated. I have saved the file on my lap and I don't know what I have to do with this file in gedit.
I will be very grateful for explaining this issue...

In reference to my previous comment I can acknowledge that the procedure works on my Lenovo G580 and Ubuntu 12.04 install from a USB-drive. I had no wireless (Broadcom) and no ethernet (Atheros), but now after two reinstalls (last one fully SUDO'd) and subsequent reboots it also works 4 me ;-) Yeai!

Hi, I downloaded the latest tar (compat-wireless-2012-09-27.pc.tar.bz2) and followed instructions above. All's well, except for one thing: when I reboot the Ethernet isn't recognized again. Am I doing something wrong? Installing in a wrong place (/home/user/Downloads/compat-wireless-2012-09-27/)? Ideas are welcome!
Thanx up front.

Thanks a lot, nitheesh, this solved the problem on a Lenovo G580. A minor correction:
Last 3 terminal commands need sudo, otherwise there will be "permission denied" errors.
