debian wheezy does not support Atheros AR956x Wireless card‏

[fanghua ye]

By the way, I remember the laptop was equiped with Win 7. 
Wheezy was successfully installed in Virtualbox with official netinstaller.
Now Win 7 is completely removed and it is surposed to install a pure Linux 
system. 
I do not know why the installer is not able to detect any network hardwares.
Do these two installation have any differences?
cheers
