  1. A modem shouldn't have a wifi security key. Only a router or gateway device should. What model number/brand is your device? If it is a router or an all in one combo then typically you should find the wifi security key on the bottom or the side. Labling varies by manufacturer. Motorola at one time was using the odd term WPA-PSK on their devices. Others say things like WiFi security key, password, etc...
  2. Open the web browser that you use and type in the IP address for your router,and press the Enter key. < Router ip addresses can be found here

    A window will open and then type in your routers default username and password,and press the Enter key again < Router usernames and passwords found here

    Navigate to the Wireless Security\Network Security Settings Tab and open it to locate or change your Security Passphrase.
    Use WPA or WPA2 because it provides better security.

    Write this Security Passphrase down and put it in a safe place .

    Save settings and close your browser.
  3. As pre-mentioned, a modem has no ip-address assignments or wireless connectivity, that is counter intuitive for security purposes.

    Assuming this is a router, use a direct connection via a cat 5 patch cord.

    I often use the dos command prompt.

    Start/Run/cmd or command

    this opens a dos shell, type in ipconfig and enter.

    the default gateway is what you need to access the router settings. (ie.

    type that ipaddress into any browser address bar or url bar.

    more than likely you will be met with a username/password prompt.

    by default most are admin for username and admin for password or blank.

    from there you should find a tab for wireless and security, it is here the WPA2 encryption is set and the code is given.
