Changed To Outdated Connection Tools

I was using my computer, and it was fine. Then my Mom used it, and when I got it back, the Internet didn't work. The network connections page looked completely different. It looked like it converted to ancient networking software. There's this American Family Insurance (my mother used to work there) connection that I didn't even know was there. They want me to use dialup for a broadband connection. All the stuff is just dial up and so old I don't remember seeing that stuff anytime recently. How do I change my network connections page so it can use wifi (what this comp has)?
