7.2.2 User Authentication

You can use WPA or WPA2 to have a RADIUS server authenticate users before they can use
the wireless network. You store each user's user name and password on the RADIUS server.
However, every wireless client in the wireless network has to support IEEE 802.1x to do this.
Unauthorized devices can still see the information that is sent in the wireless network, even if
they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless
users to get a valid user name and password. Then, they can use that user name and password
to use the wireless network.

7.2.3 Encryption

Wireless networks can use encryption to protect the information that is sent in the wireless
network. Encryption is like a secret code. If you do not know the secret code, you cannot
understand the message.
Many types of encryption use a key to protect the information in the wireless network. The
longer the key, the stronger the encryption. Every wireless client in the wireless network must
have the same key.

7.3 Wireless LAN Screen

If you are configuring the ZyXEL Device from a computer connected to the
wireless LAN and you change the ZyXEL Device's SSID, channel or security
settings, you will lose your wireless connection when you press Apply to
confirm. You must then change the wireless settings of your computer to
match the ZyXEL Device's new settings.
