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 !

1Connect to the internet by some other way and install the 4.8+ kernel
sudo apt update sudo apt install linux-generic-hwe-16.04 You also need firmware for this device. Update your system by
sudo apt update && sudo apt upgrade and the firmware will be installed.
Reboot and the wireless device should work.
To get it working out of the box, you need to install Ubuntu 16.04.2+ that has support of this device.
(I used a USB Ethernet connector for internet access. )
The updates would take a while to get done.
