I purchased a new HP Laptop (HP 2000 series). I have installed Kubuntu 12.10 ,but I am unable to use wifi. After pressing F12(wifi switch) ,I got the following info from sudo rfkill list all:

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
1: hp-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: no
2: hp-bluetooth: Bluetooth

The information showed by sudo lshw -class network command is:
