Install Madwifi for Atheros :


Open the 'terminal' by navigating through Applications-->Accessories--> Terminal

Now type the following commands in terminal

2.

Code:

sudo apt-get update && sudo apt-get upgrade

3.

sudo apt-get install build-essential libssl-dev

4.

Code:

sudo apt-get install linux-headers-`uname -r`

5.

Restart your machine.
It should work

Well i use Wicd to connect to the wireless modem
To install Wicd type the following commands in terminal

Code:

sudo apt-get update

Code:

sudo apt-get install wicd

Kernal updates of your system will kill your driver. Well no need to worry about that.Just recompile your driver.
For that you open a terminal and type the command

Code:

sudo -i

and just repeat the steps from No 8. Your madwifi will come back to life again.
