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.

3.modeprobe alx

No command 'modeprobe' found, did you mean:
Command 'modprobe' from package 'module-init-tools' (main)
modeprobe: command not found

"tar -xvf compact-wireless-2012-07-03-p.tar.bz2" is a typo: the 'compact' should read 'compat'
