Chapter 7 Wireless LAN Setup

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.

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. This field is not configurable when you select 

Enable 802.11g+.

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. This field is not configurable when you select 

Enable 802.11g+.

Passphrase

Enter a "passphrase" (password phrase) of up to 63 case-sensitive printable 

characters and click Generate to have the Prestige create four different WEP keys. 

Generate

After you enter the passphrase, click Generate to have the Prestige generate four 

different WEP keys automatically.

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 want to manually set the WEP keys, enter the key in the field provided.
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 used at any one time. The 

default key is key 1.
