If it is a secured network then who set it up? Does it use WEP, WPA/PSK WPA2
You need to know which encryption protocol is in use and whether the wireless NIC in your PC supports that level of encryption. Older systems may only support WEP and if any higher encryption is used there is nothing you can do to connect,
A network password does certainly exist.
