How do I install a driver for an Atheros AR9285?

How to install the driver for Atheros AR9285 in Ubuntu 11.10.

Still no package for 11.10 according to this

https://help.ubuntu.com/community/WifiDocs/Device/Atheros/AR9285

Here is the output of the commands

3: hci0: Bluetooth

    Hard blocked: no
4: acer-wireless: Wireless LAN
    Soft blocked: yes
    Hard blocked: no

Is there a way to make it work?

I fixed it. Edit the following file

/etc/modprobe.d/blacklist.conf

and add this

blacklist acer_wmi

Then reboot and your wifi should work ;)

I have just solved the wireless problem on Lenovo B560. However, I'm a beginner into Linux, and didn't immediately figure that blacklist acer_wmi can only be added by running the command:

gksu gedit /etc/modprobe.d/blacklist.conf
