[temple]

hello,
can someone help pls.. my wifi driver just stopped to work, i can not start it anymore:
error is:
ifconfig wlan0 up siocsifflags operation not possible due to rf-kill

my rfkill list:

0: hp-wifi: Wireless lan
Soft blocked: no
Hard blocked: yes

rfkill unblock all does not help.. Hard blocked is still yes can someone advice how to fix it? I am lost now.. thx

Hard blocked: yes

That means it is either blocked by a hardware switch or a Fn-key. You have to use an one of these to unblock the device.
