I'll try to help you as much as possible. I don't have the system with me at the moment, my girlfriend stole it.
I searched for an access point. It then recognized my network connection at home. I selected that one, and changed the settings such as password and security type (WPA/WEP) according to the settings on your router. Of course, either you or whoever is in charge of your network would need to know this information.
I hope this helps, let me know.
PS. I didn't need to know the SSID of my network connection. The only information I entered was regarding the
network password and security type.
