The types of encryption you can choose depend on the type of user authentication. (See
Section 8.2.3 on page 149 for information about this.)
For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If
users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-
PSK, or WPA2-PSK.
Usually, you should set up the strongest encryption that every wireless client in the wireless
network supports. For example, suppose the AP does not have a local user database, and you
do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless
network has two wireless clients. Device A only supports WEP, and device B supports WEP
and WPA. Therefore, you should set up Static WEP in the wireless network.
"
It is recommended that wireless clients use WPA-PSK, WPA, or stronger
encryption. IEEE 802.1x and WEP encryption are better than none at all, but it
is still possible for unauthorized devices to figure out the original information
pretty quickly.
"
It is not possible to use WPA-PSK, WPA or stronger encryption with a local
user database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.
If some wireless clients support WPA and some support WPA2, you should set up WPA2-
PSK-Mix or WPA2-Mix (depending on the type of wireless network login) in the ZyXEL
Device.
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.
