If you have a wireless network then connecting by wireless requires a password where connecting by cable does not. Do you know your network password and have you tried entering it into the computer?
Connect with the ethernet (what you call broadband) cable and go thru the router setup for the wireless side (should be in your setup guide or pdf that came on the installation disc, or download it from the router's manufacturer's website).
