Guest Wlan - ZyXEL Communications NBG6604 User Manual

The types of encryption you can choose depend on the type of user authentication. (See
information about this.)
Table 20 Types of Encryption for Each Type of Authentication
NO AUTHENTICATION
Weakest No Security
WPA-PSK
Strongest WPA2-PSK
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, 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 WPA, and device B supports WPA and WPA2. Therefore, you should set
up WPA or WPA-PSK in the wireless network.
Note: It is recommended that wireless networks 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.
Note: 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.
When you select WPA2 or WPA2-PSK in your NBG6604, you can also select an option (WPA/WPA-PSK
Compatible) to support WPA/WPA-PSK as well. In this case, if some wireless clients support WPA and
some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network
login) and select the WPA/WPA-PSK Compatible option in the NBG6604.
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.

Guest WLAN

Guest WLAN allows you to set up a wireless network where users can access to Internet via the NBG6604
(Z), but not other networks connected to the Z. In the following figure, a guest user can access the
Internet from the guest wireless network A via Z but not the home or company network N.
Note: The home or company network N and Guest WLAN network are independent networks.
Note: Only Router mode supports guest WLAN.
