Wireless Security Overview
Wireless security is vital to your network to protect wireless communication between wireless 
clients, access points and the wired network.
Wireless security methods available on the ZyXEL Device are data encryption, wireless client 
authentication, restricting access by device MAC address and hiding the ZyXEL Device 
identity.
The following figure shows the relative effectiveness of these wireless security methods 
available on your ZyXEL Device.
Table 104   Wireless Security Levels
Security Level
Security Type
Least       Secure                                                                                  
Most Secure
Unique SSID (Default)
Unique SSID with Hide SSID Enabled
MAC Address Filtering
WEP Encryption
IEEE802.1x EAP with RADIUS Server Authentication
Wi-Fi Protected Access (WPA)
WPA2
Note: You must enable the same wireless security settings on the ZyXEL Device and 
on all wireless clients that you want to associate with it. 
IEEE 802.1x
In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to 
support extended authentication as well as providing additional accounting and control 
features. It is supported by Windows XP and a number of network devices. Some advantages 
of IEEE 802.1x are:
• User based identification that allows for roaming.
• Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for 
centralized user profile and accounting management on a network RADIUS server. 
• Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional 
authentication methods to be deployed with no changes to the access point or the wireless 
clients.
