Wifi is one area which Ubuntu can not still address. The result of Atheros or Broadcom not submitting any generic code for their respective hardwares, takes a toll on Linux, as their wifi drivers are not supported out of the box.

Wifi

Here is a quick tip to get a fully functional Wifi on Linux for the wifi Atheros Network Adapter.

You need your driver CD/DVD for this.

1. Copy the ar****.inf file and the ar****.sys file to your home directory.
2. Open a terminal. Enter :

   sudo ndiswrapper -i ar****.inf

   Where ar****.sys is the file you copied. This installs the required driver. Make sure the ar****.sys file is also present in the same directory. Alternatively you can copy the files to any location and navigate to the location from the terminal before doing the above.

3. Now enter:

     sudo depmod -a
     sudo modprobe ndiswrapper

   This loads the driver you just installed, and logs any error(if any) to /var/log/messages.

4. Next, key in :

   sudo ndiswrapper -m

   This sets up the driver to load with the other network drivers at bootup.

That is all. Your wifi should be working like a breeze.
