Hide ESSID

Select Yes to hide the ESSID in so a station cannot obtain the ESSID through AP 

scanning. 
Select No to make the ESSID visible so a station can obtain the ESSID through AP 

scanning. 

Channel ID 

The radio frequency used by IEEE 802.11a, b or g 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) is for enabling RTS/CTS. 

Data with its frame size larger than this value will perform the RTS/CTS handshake. 

Setting this value to be larger than the maximum MSDU (MAC service data unit) 

size turns off RTS/CTS. Setting this value to zero turns on RTS/CTS. 
Select the check box to change the default value and enter a new value between 0 

and 2432.

Fragmentation 

Threshold 

This is the threshold (number of bytes) for the fragmentation boundary for directed 

messages. It is the maximum data fragment size that can be sent. 
Select the check box to change the default value and enter a value between 256 

and 2432.

You won’t see the following WEP-related fields if you have WPA or WPA-PSK enabled.

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. 
At the time of writing, you cannot use passphrase to generate 256-bit WEP keys. 

Generate

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

different WEP keys automatically. The keys display in the fields below. 

WEP Encryption

WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the 

wireless network. 
Select Disable to allow all wireless stations 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.
