Isn't necessary do the steps below, only install linux-backports-modules which contains the newest wifi drivers too, (and this method) use dkms, so if you do a kernel upgrade you don't have to reinstall anything!!!
Whith steps below after a kernel upgrade you have to reinstall the downloaded package!
My friend bought one of this laptop. He gave me to install Ubuntu.
I could install Ubuntu 8.10 Intrepid (32 bit) without any problem, the only thing that is not worked, was the wifi.
I found, that the laptop has Atheros AR928X chip.
I searched via google about this chip and finally now the wifi is working too!!!
The solution that worked for me I found here
So downloaded from here this
I followed the instructions from there, but at sudo make unload gave me error, that it couldn't remove one module, the mac80211.
First I had to remove the ath9k module manually (because the mac80211 module was used by this module):
After this step with sudo make unload it could remove the necessary modules.
The next and final step was sudo make load
But I saw that the ath9k module wasn't loaded, so I had to load it manually:
Now the wifi is working!!! And the wifi button light also
sudo modprobe ath9k
So I suggest you to try it!
here is some information from the working wifi:
