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

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
Threshold
Threshold
(Request To Send) The 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.
Data with its frame size larger than this value will perform the RTS/CTS handshake.

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

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.
