How do I Change the Wireless Security Settings on Windows Vista?
When you first set up a wireless network on a computer that is running the Windows Vista operating system, then you must enter a security key, which is the password for your router. You can also set up any other security settings for your wireless network, including firewall settings. All of the security settings for your wireless network can also manually be changed at any time using the Network and Sharing Center features.
