A secure broadband connection will be locked by a password that generates a security key on the network router. This security key is used by wireless computers, laptops and other devices to gain entry to the network and use the broadband internet connection. If you feel that your current security password has been compromised, you can log into your router to change the password and generate a new security key for your wireless devices.
Open an internet browser on a computer that is connected to the wireless router.
Type your router's IP address into the address bar of the browser. Depending on what brand of router you own, there may be a different default IP address. If you don't know the default IP address for your router, you can usually find it included in the documentation that came with your router.
Log in to your wireless router using the administrator username and password. If you did not change administrator account settings when you installed the router, this will be the default account. This information should also be included in the documentation that came with your router.
Navigate to the "Wireless" section of your router's dashboard and look for the "Wireless Security" settings.
Review the security settings on your router. If you are using a password, this will usually be a WEP setting.
Type a new password into the "Passphrase" text box to generate new security keys.
Write down "Key 1" and keep this information in a secure place. This will be the new security key that you will use to connect wireless computers and devices to your router.
Save your new security settings on your router to complete the password change.
You will need to change the security key on your wireless computers and devices before they can connect to your broadband internet.
