Turn on the hardware switch for your wifi adapter. –  RobinJ Jun 24 '12 at 13:49
    
What model is your laptop, as robinj says, hard block refers to a real life hardware switch. If you can tell me the model I can look it up. –  Shutupsquare Jun 24 '12 at 14:46
    
MSI CR630 - this is it –  Cristian Jun 24 '12 at 22:21

Try:

rfkill unblock all

..or what RobinJ mentioned, try the hardware switch on your laptop:

hardware wifi wireless switch

robinJ thanks but i believe that if i were able to give you that much info from the terminal than i am able to find which are the keys for turning on my wlan. Unfortunately already tried it and it doesn't work. It doesn't look like the one in the picture provided by medigeek but i have FN+F10. (It didn't work but FN+-> works in controlling the audio level) –  Cristian Jun 24 '12 at 14:40
    
And i tried with rfkill unblock all ----> no succes –  Cristian Jun 24 '12 at 14:41

I found this and it worked for me.

This is how to get the wireless hardswitch to turn on using the terminal:

sudo apt-get remove bcmwl-kernel-source
sudo apt-get install firmware-b43-installer
sudo apt-get install b43-fwcutter

Then enter this command to turn it on:

cat /etc/modprobe.d/* | egrep '8180|acx|at76|ath|b43|bcm|CX|eth|ipw|irmware|isl| lbtf|orinoco|ndiswrapper|NPE|p54|prism|rtl|rt2|rt3 |rt6|rt7|witch|wl'

Reboot and see if it stays on.
