Actually, if the OP bought the router and it is new, it will have a default username and password (provided by the vendor) and no security keys/passphrases at all.
The answer to the original question, ask whoever owns the network you are trying to connect to for the information.
Get a grip, Brett. OP is asking for a router pw. Maybe if he read the manual he would have found it. My ISP modem has an access code sticker on the bottom of the modem, my router(s) have fairly common access code like 192.168.1.1 or whatever and pw's like admin. Geez! My modem and routers are wired BTW. If you have wireless you should change the codes ASAP to prevent eavesdroppers and hackers.
His question is valid and allowed.
