I have a laptop with the Intel Centrino N-1000 wireless card running Ubuntu 12.10.

The Ethernet card works fine, but the wireless card doesn't.

When I click the Networking icon I see that wireless is disabled by hardware switch.

I checked the switch on my laptop and it is ON!a

I tried:

-Restarting the Computer

-Copying the ucode firmware file to /lib/firmware

-sudo iwconfig wlan0 power off && sudo iwconfig wlan0 power on 

-Going to Settings>Software Sources>Additional Drivers but "No propertiary drivers are in use"

Still the same problem.
EDIT:
After typing sudo rfkill list I discovered the wireless card was soft-blocked and hard-blocked.

I typed sudo rfkill unblock wifi.

Now the card is still hard blocked.

```
user@linux-laptop:~$ sudo rfkill list 
0: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no
1: phy0: Wireless LAN
