Bug Description
NetworkManager always reports "Wireless is disabled", and the acer_wmi rfkill device in sysfs always reports state=0. Trying to write 1 to the rfkill device state doesn't produce errors, but it doesn't produce any results either, i.e. the state stays set at 0 and the wireless radio stays off. Removing the acer_wmi module removes the rfkill device, turning on the wireless radio.
I also tested this with upstream kernel using the 2.6.34-

Hi Tommaso,
If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/ /wiki.ubuntu. com/KernelMainl ineBuilds . Once you've tested the upstream kernel, please remove the 'needs- upstream- testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs- upstream- testing' text. Please let us know your results.
Thanks in advance.
