Chapter 22 LAN Setup

Your ZyXEL device checks the MAC address of the wireless station device against a list of 
allowed or denied MAC addresses. However, intruders could fake allowed MAC addresses so 
MAC-based authentication is less secure than EAP authentication. 

Follow the steps below to create the MAC address table on your ZyXEL device.

1 From the main menu, enter 3 to open Menu 3 – LAN Setup.

Key 1 to Key 4

The WEP keys are used to encrypt data. Both the ZyXEL device and the wire-
less stations must use the same WEP key for data transmission.
If you chose 64-bit WEP in the WEP Encryption field, then enter any 5 ASCII 
characters or 10 hexadecimal characters ("0-9", "A-F"). 
If you chose 128-bit WEP in the WEP Encryption field, then enter 13 ASCII 
characters or 26 hexadecimal characters ("0-9", "A-F").

Note: Enter “0x” before the key to denote a hexadecimal key. 

Don’t enter “0x” before the key to denote an ASCII key

Authen. Method

Press [SPACE BAR] to select Auto, Open System Only or Shared Key Only 

and press [ENTER]. 
This field is N/A if WEP is not activated. 
If WEP encryption is activated, the default setting is Auto.

See the following section for details on this field.

Edit Roaming 

Configuration

Press [SPACE BAR] to select Yes to enable roaming on the ZyXEL device if 

you have two or more ZyXEL devices on the same subnet.

Note: All APs on the same subnet and the wireless stations must 

have the same ESSID to allow roaming.

Breathing LED

Select Yes to enable the Breathing LED, also known as the ZyAIR LED.
The blue ZyAIR LED is on when the ZyXEL device is on and blinks (or breaths) 

when data is being transmitted to/from its wireless stations. Clear the check box 

to turn this LED off even when the ZyXEL device is on and data is being 

transmitted/received.

Preamble 

Press [SPACE BAR] to select a preamble type. Choices are Long, Short and 

Dynamic. The default setting is Long.
See the section on preamble for more information.

802.11 Mode

Press [SPACE BAR] to select B Only to allow only IEEE 802.11b compliant 

WLAN devices to associate with the ZyXEL device.
Select G Only to allow only IEEE 802.11g compliant WLAN devices to 

associate with the ZyXEL device.
Select Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN 

devices to associate with the ZyXEL device. The transmission rate of your 

ZyXEL device might be reduced.

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.
