I previously installed Ubuntu 10.04 on my laptop. That version installed wireless driver automatically and it worked well. But now I have installed Ubuntu 11.10 and cann't enable it's wireless. My laptop has a physical "wireless device switch" that for enabling its wireless, it has to switched on.
When I run "System Settings" >> "Additional Drivers" it announces "No proprietary drivers are in use on this system"
My laptop is Lenovo Ideapad U330 and below is some information about my laptop network specs:

After applying iwlagn changes, although my laptop's "physical wireless switch" is on and I press Fn+F5 key combination, network manager cannot detect it and announces that wireless is disabled by hardware switch.
I use Ubuntu 11.10 as sole OS on my laptop.
