- Value : You can enter a shared key as Text . Use a longer text sequence with
alphanumeric characters and special characters to enhance the shared key strength. A
text shared key is case sensitive. Alternatively, the shared key can be entered as
Hex
value (hexadecimal number, 0-9, a-f). Press the Generate button to generate a random
shared key that matches the current settings.
• 802.1x (Radius) : Enable this option to use the RADIUS authentication without the
stronger WPA encryption. You also need to specify the Radius settings and you may
adapt the Key settings (see below).
• MAC access filters (on / off, default: off): You can limit WLAN access for WLAN clients
with specified MAC addresses. Note, that without encryption this should not be used for
security reasons. Press the
Configure button to enter a list of MAC addresses that are
allowed to connect.
• BSS isolation (on / off, default: off): In a standard WLAN setup, each WLAN client can
contact other WLAN clients. For special purposes (e.g. “Internet café setup”), you may
switch on this options to protect WLAN clients from eavesdropping on other WLAN clients.
Key settings
• Cipher length (selection, 64 Bits / 128 Bits / 256 Bits, default: 64 Bits): Determines the
key length used for the WEP encryption. Larger bit sequences provide better security but
may be unsupported by very old WLAN clients.
• Distribution interval (seconds, 1..65535, default: 20): Determines how often the WEP
encryption is re-negotiated.
Radius settings
The parameters in this section can only be configured if the
802.1x (Radius) option has been
selected.
• IP address : Enter the IP address of the RADIUS server.
• Port : Enter the port number used to connect to the RADIUS server. Press the Default
button to change to the standard port.
• Secret : Enter the character string that is used by the RFP to secure the communication
with the RADIUS server.
QoS settings
• WME with : (on / off, VLAN or DiffServ, default: off/VLAN): You can enable the Wireless
Media Extensions to prioritize WLAN traffic. The WLAN traffic priority is determined by
VLAN number or by examining the DiffServ data field of IP packets.
Multiple SSID (SSID2 – SSID4)
You can enable up to three additional virtual WLAN networks that are managed by their
SSID. This can be used for example to provide WLAN access for guests that is separated
from the company WLAN by means of VLAN tags and encryption settings. To activate this
feature proceed as follows:
1 Switch on the VLAN tag checkbox and enter the desired number under General settings
(see above).
2 Activate the check box next to the desired SSID 2 , SSID 3 , or SSID 4 heading. This will
unfold a new settings area that provides separate configuration items for the selected
SSID.
