Hi, i just installed recalbox on an pc (hp pavillion dv 6 6118sl), but i can't connect my pc to wifi.
When i run ifconfig there isn't wlan0 and when i "run rfkill list all" hp-wifi is hard-blcoked.. what can i do?

#rfkill list all
0: hp-wifi: Wireless LAN
        Soft blocked: no
        Hard blocked: yes
