Forgive me for being so dumb, I went to the website for my model (Linksys BEFW11S4) and found out that there is a web-program that allows you to set all of the passwords and keys for the AP/Router (I should have done this in the first place instead of jumping for help and pesting people). The website was an IP address (
http://192.168.1.1), only accessable through a PC connected to the router. It was pretty nifty, I didn't even know it exsisted. It contained all kinds of configuration options, IP data, logs, etc. I did find the box though, I went *sneaking*, and it contained no manual nor CD. Hmm... It did have a bunch of cardboard and plastic in it though...
Thanks for the help!
