[WPCentral Question]

I downloaded windows 10 on my hp pavilion dv7 notebook pc and lost wi-fi

I did a fix where I entered 2 lines of code which allowed me to see available networks but when I attempted to connect, I got limited internet? and in Action Center in Windows 10 it says 'not connected to internet.

This sucks!!!!
