I am running Ubuntu 11.10 on a Compaq Presario CQ57 and I need to enable my wireless hardware switch to use it. I have a wireless key (F12) which shows a light when the switch is active (it is now red). How would I go about enabling in Ubuntu? I've tried pressing F12 normally and with Fn, none work.

I have found out that pressing F12 does switch the switch, but wireless is disabled anyway. Am I missing a driver? Apr 6, 2012 at 21:56

There is a step missing in that instruction.Run
sudo apt-get update
after adding ppa– Web-EApr 7, 2012 at 6:22 -
Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference.– fossfreedom ♦Apr 7, 2012 at 8:12

Okay, I have fully solved the hardware switch problem. But it is still displaying that it is disabled. Apr 7, 2012 at 13:54

Try to unload the wmi module.
For example, this worked for me on HP Mini 100e:
sudo rmmod hp-wmi
sudo rmmod wmi
after which I could immediately connect to wi-fi.
(Find your corresponding module using lsmod)
If this works for you, you might want to blacklist the wmi module from /etc/modprobe.d/ -- see link for instructions.
