Just now I have installed 9.04 in my Lenovo z570. I am new to Ubuntu. By searching on various community, I come to know that I need to install wifi drivers to make wifi run because the output of lshw -c network shows that wireless drivers are unclaimed and output of iwconfig shows No wireless extensions. My laptop specifications are as below.

  • Wireless adapter : Atheros AR9285
  • Linux kernel version of OS : Ubuntu 9.04

Please guide me from where to download this drivers and how to install it.
