Encryption and Security
Many kinds of encryption are available. WEP
works with almost everything. WPA2-PSK is
much more secure. Choose the strongest method
of encryption that works with all of your wireless
devices.
Enter a network key ("password") twice. Write
down your password and put it in a safe place.
You will not be able to connect wireless devices to
your network without this password.
