LABEL DESCRIPTION
Channel ID The radio frequency used by IEEE 802.11b wireless devices is called a channel.
Select a channel from the drop-down list box.
RTS/CTS
Threshold The RTS (Request To Send) threshold (number of bytes) for enabling RTS/CTS handshake.
Data with its frame size larger than this value will perform the RTS/CTS handshake. Setting
this attribute to be larger than the maximum MSDU (MAC service data unit) size turns off the
RTS/CTS handshake. Setting this attribute to zero turns on the RTS/CTS handshake.
Enter a value between 0 and 2432.
Fragmentation
Threshold The threshold (number of bytes) for the fragmentation boundary for directed messages. It is
the maximum data fragment size that can be sent.
Enter a value between 256 and 2432.
WEP Encryption WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless
network.
Select Disable to allow all wireless computers to communicate with the access points without
any data encryption.
Select 64-bit WEP , 128-bit WEP or 256-bit WEP to use data encryption.
Key 1 to Key 4 The WEP keys are used to encrypt data. Both the Prestige and the wireless stations must use
the same WEP key for data transmission.
If you chose 64-bit WEP , then enter any 5 ASCII characters or 10 hexadecimal characters ("0-
9", "A-F").
If you chose
128-bit WEP , then enter 13 ASCII characters or 26 hexadecimal characters ("0-
9", "A-F").
If you chose 256-bit WEP , then enter 29 ASCII characters or 58 hexadecimal characters ("0-
9", "A-F").
The values for the WEP keys must be set up exactly the same on all wireless devices in the
same wireless LAN.
You must configure all four keys, but only one key can be activated at any one time. The
default key is key 1.

6.5 Configuring MAC Filter
The MAC filter screen allows you to configure the Prestige to give exclusive access to up to 32
devices (Allow Association) or exclude up to 32 devices from accessing the Prestige (Deny
Association). Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address is assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02. You need to know the MAC address of the devices to configure this screen.
To change your Prestige’s MAC filter settings, click Wireless LAN , MAC Filter to open the MAC
Filter screen. The screen appears as shown.
