wolf@wolf:~$ sudo ifup wlan0
Ignoring unknown interface wlan0=wlan0.

any idea would be greatly appreciated
UPDATE : results of lspci -nn | grep 0280

wolf@wolf:~$ lspci -nn | grep 0280

02:00.0 Network controller [0280]: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter [168c:0036] (rev 01)

Your relatively new device 168c:0036 isn't covered in your relatively old 3.2.0-xx kernel. You can correct this by installing the wireless modules backported from kernel version 3.8. First, identify your kernel details:

uname -r

Your kernel will either be 3.2.0-xx-generic or -generic-pae. Obtain a temporary internet connection and open a terminal and do:

sudo apt-get update
sudo apt-get install linux-backports-modules-cw-3.8-precise-generic

Or:

sudo apt-get update
sudo apt-get install linux-backports-modules-cw-3.8-precise-generic-pae

As needed. Reboot and your wireless should be working.
