Uninstalled Wireless Driver?

Hello,

I mistakenly removed the wifi connectivity from wife's HP Envy. I believe I was attempting to use the control panel to change her driver or software itself but instead the software was removed.

I attempted to download the drivers from Microsoft and HP but have been unable to establish a wireless connection or even see the adapter as an option anywhere on the computer.

She is running Windows 8.

Please help! Thanks
