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.
