2.2 Wireless LAN Security
Wireless LAN security is vital to your network to protect wireless communication between wireless
stations and the wired network.
The figure below shows the possible wireless security levels on your ZyXEL G-162. EAP (Extensible
Authentication Protocol) is used for authentication and utilizes dynamic WEP key exchange. It requires
interaction with a RADIUS (Remote Authentication Dial-In User Service) server either on the WAN or
your LAN to provide authentication service for wireless stations.
