Thanks hiren and heffemeister, you got me on the right track. I can't remember my username/password right now, but I've got the screen I think that will let me change those settings, just gotta find where I wrote the username/password down.
what you could do for that is a MAC address filter.... i know the linksys routers have it but not sure bought yours.... if you do have it, it would be somewhere in your wireless configuration settings
