Upgrading HP Compaq 6715s with a Motorola Surfboard SBG6580 wireless card

So after pulling apart the dead modem/router I wanted to use the only working part scavenged.

I opened my wife's laptop to access the wi-fi card. This is the easy part as it is just one screw for the panel and 2 screws that hold the wi-fi card in place.
