10/100M Auto-
negotiating Ethernet/
Fast Ethernet Interface
This auto-negotiating feature allows the ZyXEL Device to detect the speed of 
incoming transmissions and adjust appropriately without manual 
intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either 
half-duplex or full-duplex mode depending on your Ethernet network.
Ethernet port connections can be in half-duplex or full-duplex mode. Full-
duplex refers to a device's ability to send and receive simultaneously, while 
half-duplex indicates that traffic can flow in only one direction at a time. The 
Ethernet port must use the same speed or duplex mode setting as the peer 
Ethernet port in order to connect.
10/100M Auto-
crossover Ethernet/Fast 
Ethernet Interface
The LAN interface automatically adjusts to either a crossover or straight-
through Ethernet cable. 
Reset Button
The reset button is built into the rear panel. Use this button to restart the 
device or restore the factory default password. 
802.11g Wireless LAN 
Standard
The ZyXEL Device complies with the IEEE 802.11g wireless standard.
IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This 
means an IEEE 802.11b radio card can interface directly with an IEEE 
802.11g access point (and vice versa) at 11 Mbps or lower depending on 
range. 
Wi-Fi Protected Access
Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. Key 
differences between WPA and WEP are user authentication and improved 
data encryption.
WPA2
WPA 2 (IEEE 802.11i) is a wireless security standard that defines stronger 
encryption, authentication and key management than WPA.
SSL Passthrough
The ZyXEL Device allows SSL connections to go through the ZyXEL Device.  
SSL (Secure Sockets Layer) uses a public key to encrypt data that's 
transmitted over an SSL connection. Both Netscape Navigator and Internet 
Explorer support SSL, and many Web sites use the protocol to obtain 
confidential user information, such as credit card numbers. By convention, 
URLs that require an SSL connection start with "https" instead of "http". 
Wireless LAN MAC 
Address Filtering
Your ZyXEL Device checks the MAC address of the wireless station against 
a list of allowed or denied MAC addresses.
WEP Encryption
WEP (Wired Equivalent Privacy) encrypts data frames before transmitting 
over the wireless network to help keep network communications private.
IEEE 802.1x Network 
Security
The ZyXEL Device supports the IEEE 802.1x standard to enhance user 
authentication. Use an EAP-compatible RADIUS (RFC2138, 2139 - Remote 
Authentication Dial In User Service) server to authenticate a limitless 
number of users using EAP (Extensible Authentication Protocol). EAP is an 
authentication protocol that supports multiple types of authentication.
Full Network 
Management 
The embedded web configurator is an all-platform web-based utility that 
allows you to easily access the ZyXEL Device's management settings. 
Logging and Tracing
Built-in message logging and packet tracing.
Wireless Association 
List
With the wireless association list, you can see the list of the wireless stations 
that are currently using the ZyXEL Device to access your wired network. 
When the ZyXEL Device is in client mode, the wireless association list 
displays a list of wireless devices and networks in the area.
