Ubuntu 12.10 HP Pavilion dm4 wireless not working

I have a HP Pavilion dm4 that initially came with Windows 7. I upgraded to Windows 8 and then replaced that with Ubuntu 12.10. The WiFi worked fine until I installed the software upgrades right after installing the os. There is a hardware switch for WiFi and Bluetooth and it is on.

rfkill list all results:

2: hp-bluetooth: Bluetooth

    Soft blocked: no

    Hard blocked: no

3: hp-wifi: Wireless LAN

    Soft blocked: no

    Hard blocked: no

4: hci0: Bluetooth

    Soft blocked: no

    Hard blocked: no

In the Network settings, I only see Wired and Network Proxy, no wireless. I am currently connected to a wired network to resolve this issue.

By typing the command :

lspci

You can check what kind of wireless card your HP pavillon have. I guess it's probably something like bcm43xx.

If so, the answer to get your wifi working is :

sudo apt-get install linux linux-headers-generic kernel-package

sudo apt-get purge b43-fwcutter firmware-b43-installer firmware-b43-lpphy-installer firmware-b43legacy-installer bcmwl*

sudo apt-get install b43-fwcutter firmware-b43-lpphy-installer bcmwl*

Reboot !
