I just bought a reconditioned Dell Vostro 1500 for Grad School, and I cannot connect to my WPA protected Wireless Router (Linksys WRT54GP2).

Dell Wireless Utility is asking for my Network Key, I put in the password for the router, but it does not connect. How do I find my Network Key from the Router Utility?
