DESCRIPTION

 

 

 

 

 

 

Enable Wireless

The wireless LAN is turned off by default, before you enable the wireless LAN you

 

 

LAN

should configure some security by setting MAC filters and/or 802.1x security; otherwise

 

 

 

your wireless LAN will be vulnerable upon enabling it. Select the check box to enable

 

 

 

the wireless LAN.

 

 

ESSID

(Extended Service Set IDentification) The ESSID identifies the Service Set the station

 

 

 

is to connect to. Wireless clients associating to the Access Point must have the same

 

 

 

ESSID. Enter a descriptive name (up to 32 characters) for the wireless LAN.

 

 

 

 

 

 

Hide ESSID

Select to hide the ESSID in the outgoing beacon frame so a station cannot obtain the

 

 

 

ESSID through passive scanning.

 

 

 

 

 

 

Channel ID

This allows you to set the operating frequency/channel depending on your particular

 

 

 

region. Select a channel from the drop-down list box.

 

 

 

 

 

 

RTS/CTS

(Request To Send) The threshold (number of bytes) for enabling RTS/CTS handshake.

 

 

Threshold

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

The threshold (number of bytes) for the fragmentation boundary for directed messages.

 

 

Threshold

It is the maximum data fragment size that can be sent. Enter a value between 256 and

 

 

 

2432.

 

 

WEP Encryption

WEP (Wired Equivalent Privacy) provides data encryption to prevent unauthorized

 

 

 

wireless stations from accessing data transmitted over the wireless network.

 

 

 

Select Disable to allow wireless clients to communicate with the access points without

 

 

 

any data encryption.

 

 

 

Select 64-bit WEP or 128-bit WEP to enable data encryption.

 

 

 

Although WEP is functional at 5.5 and 11 Mbps, there is significant performance

 

 

 

degradation when using WEP at these rates.

 

 

 

 

 

 

Key 1 to Key 4

If you chose 64-bit WEP in the WEP Encryption field, then enter any 5 characters

 

 

 

(ASCII string) or 10 hexadecimal characters ("0-9", "A-F") preceded by 0x for each key.

 

 

 

If you chose 128-bit WEP in the WEP Encryption field, then enter 13 characters

 

 

 

(ASCII string) or 26 hexadecimal characters ("0-9", "A-F") preceded by 0x for each key.

 

 

 

There are four data encryption keys to secure your data from eavesdropping by

 

 

 

unauthorized wireless users. The values for the keys must be set up exactly the same

 

 

 

on the access points as they are on the wireless client computers.
