Enabling wireless hardware switch

Question

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.

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.
