This issue still occurs, even in Ubuntu 13.10.

Here is an example:

Workaround solution was to blacklist the acer_wmi module.

Title:
  acer_wmi in Jaunty on Aspire One exposes non-functional (always
  disabled) rfkill device

Status in “linux” package in Ubuntu:

Status in “linux” source package in Jaunty:

Status in “linux” package in Fedora:

Bug description:
  Upgrading to Jaunty, I found that network-manager would no longer let
  me make any wireless connections - it turned out that it thought that
  a killswitch was triggered (in /var/log/daemon.log). However, "iwlist
  wlan0 scan" could see networks. Toggling the killswitch apparently did
  turn the radio off and on, as evidenced by the response of "iwlist
  wlan0 scan", but network-manager remained convinced that radio was
  killed throughout.

  I discovered that the acer_wmi rfkill device in sysfs was reporting
  state="0" regardless what state the killswitch was actually in.
  Investigating the modules website at
  http://code.google.com/p/aceracpi/wiki/SupportedHardware revealed the
  comment that the WMI implementation on the Aspire One does not do
  anything. Based on that assertion, I did "rmmod acer_wmi", and
  network-manager sprang into life and happily connected my network.
