i would google the make and model. if you have not changed it, it is probably the default and should be listed in some literature

Thanks DouglasBPowers

default password on linksys is admin. Which should be changed, btw. Even if you have security on, I can get in to your network if I know PW.

Thanks JerryButler Turns out I changed the password, but still couldn't get going. We were trying to get our Wii connected to wireless

The Wii can be a bit funky about wireless. It refuses to connect to my high end Cisco APs at work. Linksys is owned by Cisco.. hmmm

Hmmmm...that is interesting JerryButler
