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.

My PC is currently connected to the modem via an ethernet link. Instead, I established a two-way connection in the following way: 1) Router - modem via ethernet cable. 2) PC - Router via an ethernet cable. However when I do this, my PC is not able to connect to the internet. I am wondering if anyone can help me out with this.

Hello, I tried to take compat-wireless-2012-05-09.tar.bz2 but in the last lines it replied
make : Error 2
alx: Fatal Error

We installed Ubuntu 12.04 and the Laptop is a Lenovo G 580

I also tried the method Sandjeev recommended, but works neither.

Thanks for you help!

I followed the steps and everything was working fine, but after I type in sudo make install, it says some stuff, then the last thing I see is /boot/ ... and then nothing. When I try to close terminal is says it's still performing an action and that would terminate it. Should I leave this here? It's been like 20 minutes, how long could this take or did I do something wrong?

Hello
At first i had a similar problem, with ifconfig i could only see lo but not eth0.
After installing the dirver i could finally see eth0 but still no internet connection
and here is a funny thing, i can connect only wireless BUT only using a browser.
I have no connection when i try to use a terminal (i.e ping or apt-get).

any ideas? :(

thx
