Once you enable user authentication, you need to specify an external RADIUS server or create 
local user accounts on the ZyXEL device for authentication

Dynamic WEP Key 

Exchange

This field is activated only when you select Authentication Required in the 

Wireless Port Control field. Also set the Authentication Databases field to 

RADIUS Only. Local user database may not be used.  
Select Disable to allow wireless stations to communicate with the access 

points without using Dynamic WEP Key Exchange. 
Select 64-bit WEP or 128-bit WEP to enable data encryption. 
Up to 32 stations can access the ZyXEL device when you configure Dynamic 

WEP Key Exchange.

PSK

Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including 

spaces and symbols) when you select WPA-PSK in the Key Management 

Protocol field. 

WPA Mixed Mode

Select Enable to activate WPA mixed mode. Otherwise, select Disable and 

configure Data Privacy for Broadcast/Multicast packets field.

WPA Group Key 

Update Timer

The WPA Broadcast/Multicast Key Update Timer is the rate at which the AP 

(if using WPA-PSK key management) or RADIUS server (if using WPA key 

management) sends a new group key out to all clients. The re-keying process 

is the WPA equivalent of automatically changing the WEP key for an AP and all 

stations in a WLAN on a periodic basis. Setting of the WPA Broadcast/

Multicast Key Update Timer is also supported in WPA-PSK mode. The ZyXEL 

device default is 1800 seconds (30 minutes).

Authentication 

Databases

The authentication database contains wireless station login information.  The 

RADIUS is an external server.
When you configure Key Management Protocol to WPA, the Authentication 

Databases must be RADIUS Only. 
Select RADIUS Only to have the ZyXEL device just check the user database 

on the specified RADIUS server for a wireless station's username and 

password. 

When you have completed this menu, press [ENTER] at the prompt “Press ENTER to confirm or ESC 

to cancel” to save your configuration or press [ESC] to cancel and go back to the previous screen.
