Desktop internet connectivity help!

[maranthony92]

Okay I'm building a new desktop computer in my room but I need a way to connect it. My dads desktop computer in the house has a router. Can i buy a USB wireless adapter and connect it via wifi like mobile laptops do? And if I can , can someone tell me the steps to do it? Which one to buy ? Do I have to install any software ??
Thank you

You can get a wifi USB adapter or a wifi PCI card, it's bee speculated back and forth which is better but I'd go with card. Like this... http://www.newegg.com/Product/Product.aspx?Item=N82E16833320074
Though I would have wifi as a last resort for a desktop PC. Is there no way to wire from the router?
