Prestige 650H/HW

The following table describes the fields in this screen.

Table 3 Wireless LAN: Wireless

LABEL DESCRIPTION

ESSID (Extended Service Set IDentity) The ESSID is a unique name to identify the Prestige in the

wireless LAN. Wireless clients associating to an Access Point (the Prestige) must have the same

ESSID. Enter a descriptive name (up to 32 printable 7-bit ASCII characters).

Hide ESSID Select Yes to hide the ESSID so a wireless client cannot obtain the ESSID through passive

scanning.

Select No to make the ESSID visible so a wireless client can obtain the ESSID through passive

scanning.

Channel ID The range of radio frequencies used by IEEE 802.11b wireless devices is called a channel. Set

the operating frequency/channel depending on your particular region.

Select a channel from the drop-down list box. Adjacent APs with overlapping coverage areas

should use different channels to reduce crosstalk. Crosstalk occurs when the radio signals from

access points overlap and interfere with one another degrading performance.

RTS/CTS

Threshold

Select this option to enable the RTS (Request To Send)/CTS (Clear To Send) threshold to

minimize collisions. Enter a value between 0 and 2432. The default is 2432.

Request To Send is the threshold (number of bytes) for enabling the 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.

Fragmentation

Threshold

Fragmentation Threshold is the maximum data fragment size that can be sent.

WEP

Encryption

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

wireless network.

Select Disable allows all wireless computers to communicate with the access points without any

data encryption.

Select 64-bit WEP or 128-bit WEP and then configure the keys in the fields provided to activate

data encryption.

Key 1 to Key 4 The WEP keys are used to encrypt data. Both the Prestige and the wireless clients must use the

same WEP key for data transmission.

If you chose 64-bit WEP, then enter any 5 characters (ASCII string) or 10 hexadecimal

characters ("0-9", "A-F").

If you chose 128-bit WEP, then enter 13 characters (ASCII string) or 26 hexadecimal characters

("0-9", "A-F").

Select only one key to be activated at any one time.
