Public bug reported:
Since upgrading (from 11.04 to 12.04) as a fresh install, I am
experiencing the following issue.
If I switch the hardware switch of my wifi off, I can never turn it back
on. I constantly get the message 'RF-Kill: Disabled by hardware switch'
or similar.
After a lot of google searching, the following script works to fix the
issue:
rmmod -f iwlwifi
rfkill unblock all
modprobe iwlwifi
Although, this isn't really a good solution every time I want to turn
the WiFi off, or do it accidentally since the switch is in an awkward
place.
