Enabling Encryption
Because wireless networks transmit data using radio frequency transmission, other computers with wireless network adapters
that are within range of your wireless broadband router can connect to your network. You can deter unauthorized access to
your wireless network by enabling encryption. When you enable encryption, you must specify a network encryption key, or
simply, network key. The network key can be a combination of numbers, letters, or numbers and letters. The network key must
match the network key that you specified at your wireless broadband router.
