22.4.1 Configuring MAC Address Filter
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

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.
