Trouble connecting to my Wi-Fi?

I just purchased a refurbished pc (hp compaq dc7800) and for some reason I can't connect to my wireless network with it. With the previous desktop I had I was able to connect to the Internet with it, every other device (laptops, iPhones, etc) are able to connect to it but not this pc. I have tried going into "set up a network" and nothing pops up, it won't even recognize wireless at all and just asks if I want to connect with an Ethernet cable. So I'm at a loss here, and not sure what to do, any suggestions?

Sounds like the drivers for the Wi-Fi card are missing. Are you sure this computer even has a Wi-Fi network card?

I tried to reinstall it like 5 times and still th same, Tried restarting phone, tried all the obvious.
