wireless

I have a problem where Ubuntu (12.04) says there is a wireless network card, but it is disabled by a hardware switch. How do I turn it on?

I checked the BIOS, and the wireless card is enabled there.

Fn + F2 was also no success.

The results of rfkill list:

0: brcmwl-0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes
1: dell-wifi: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes

sudo rfkill unblock wifi did nothing to the Wireless Status.
