What Is a Network Key?

A network key is an encrypted series of characters that enhances security in a wireless network. A network key is essential to prevent anyone from having unauthorized access to a network.

To secure a wireless network:

  1. Set up a new wireless network using the Network and Sharing Center feature on the computer.
  2. Give the network a name, and choose a passphrase.
  3. Use the recommended security level and encryption type.
  4. Enable firewalls for even better surveillance against intruders.

Another way to access the router's configuration is to use the default gateway IP address. The settings accessed there allow customization of features to enhance security.
