I'm trying to set up. I'm trying to set up my Mom's new Gateway laptop to her new Netgear router

Question

I'm trying to set up my Mom's new Gateway laptop to her new Netgear router through a ewire modem, so she can use her computer anywear in her house. We ordered the net gear pc card and it does not fit properly. After calling them back (Kanokla, the company that sold the Netgear products to us) they told us that we probably didn't need the card, it should be built in. Please help!
