Hello,

I upgraded to 12.04 yesterday at which point my wireless stopped working entirely. When I left-click on the networking widget, the menu does not even offer the "Enable Wireless Networking" option anymore.

I have made sure that the hardware is turned on.

I have appended: "blacklist acer_wmi" to /etc/modprobe.d/blacklist.conf

Nothing worked. I need help.

Code:
$ uname -a
Linux armence 3.2.0-34-generic #53-Ubuntu SMP Thu Nov 15 10:49:02 UTC 2012 i686 i686 i386 GNU/Linux
Code:
$ lspci -nn | grep Network
02:00.0 Network controller [0280]: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01)
Code:
$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.
Code:
$ rfkill list all
Not a typo. Nothing was displayed.

Code:
$ lsmod
