Haha, lucky you! I tried getting on, and it turns out there are four WiFis if I step outside. Two of them have the same WPA problem, and the other two have passwords.
Thanks for the help on the WiFi! The router isn't really mine, so I don't want to mess with the settings or anything. I'm going to try to get into a neighbor's passwordless WiFi tonight, since mine apparently has to be changed in order to work. I'll let you know how it goes!
