Disable Wireless

Hello everyone .

I'd like to know if it is possible to disable a wireless card or block all wireless connections .
If so, does anybody know how to do that ?

Any info apreciated .

Thanks in advance,
HelderMPinhal

I am pretty sure I read about doing this in a post here recently as I was searching for something else.

Think you have to use a shell command, I will see if I can re find the thread.

-- Why do you wish to block all wireless cards and connections???
