Fragment Threshold Fragmentation mechanism is used for improving the
efficiency when high traffic flows along in the wireless
network. If your 802.11g Wireless LAN PC Card often
transmit large files in wireless network, you can enter new
Fragment Threshold value to split the packet. The value
can be set from 256 to 2346. The default value is 2346.
RTS Threshold RTS Threshold is a mechanism implemented to prevent the
“Hidden Node” problem. “Hidden Node” is a situation in
which two stations are within range of the same Access
Point, but are not within range of each other. Therefore, they
are hidden nodes for each other. When a station starts data
transmission with the Access Point, it might not notice that
the other station is already using the wireless medium. When
these two stations send data at the same time, they might
collide when arriving simultaneously at the Access Point.
The collision will most certainly result in a loss of messages
for both stations.
Thus, the RTS Threshold mechanism provides a solution to
p
revent data collisions. When you enable RTS Threshold on
a suspect “hidden station”, this station and its Access Point
will use a Request to Send (RTS). The station will send an
RTS to the Access Point, informing that it is going to
transmit the data. Upon receipt, the Access Point will
respond with a CTS message to all station within its range to
notify all other stations to defer transmission. It will also
confirm the requestor station that the Access Point has
reserved it for the time-frame of the requested transmission.
If the “Hidden Node” problem is an issue, please specify the
packet size. The RTS mechanism will be activated if the data
size exceeds the value you set.. The default value is 2347.
Warning: Enabling RTS Threshold will cause redundant
network overhead that could negatively affect the
throughput performance instead of providing a remedy.
This value should remain at its default setting of 2347. Should you
encounter inconsistent data flow, only minor modifications of this
value are recommended.
Beacon Interval Beacon Interval is the amount of time between beacon
transmissions. Before a station enters power save mode, the
station needs the beacon interval to know when to wake up
to receive the beacon (and learn whether there are buffered
frames at the access point).
Data Rate By default, the unit adaptively selects the highest
p
ossible

15
rate for transmission. Select the basic rates to be used among
the following options: Auto, 1, 2, 5.5, 11or 54 Mbps. For
most networks the default setting is Auto which is the best
choice. When Auto is enabled the transmission rate will
select the optimal rate. If obstacles or interference are
p
resent, the system will automatically fall back to a lower
rate.
Preamble Type A preamble is a signal used in wireless environment to
synchronize the transmitting timing including
Synchronization and Start frame delimiter. In a “noisy”
network environment, the Preamble Type should be set to
Long Preamble. The Short Preamble is intended for
applications where minimum overhead and maximum
p
erformance is desired. If in a “noisy” network environment,
the performance will be decreased.
Hide SSID Select enabled to allow all the wireless stations to hide the
SSID of this router.
Tx Burst Select the check box to enable the Tx Burst function.
802.11g Protection The 802.11g standard includes a protection mechanism to ensure
mixed 802.11b and 802.11g operations. If there is no such kind of
mechanism exists, the two kinds of standards may mutually
interfere and decrease network’s performance.
AckTimeOut Maximum time, in microseconds, that the failover daemon
will wait for an ACK or NOACK message to be received
from the peer failover daemon. For each message the
failover daemon sends, the peer failover daemon sends an
ACK or NOACK message to indicate that the peer is still
functioning.
Default: 50 microseconds
Apply Change Press to save the new settings on the screen.
Reset Press to discard the data you have entered since last time
you press Apply Change.
Security
Here you can configure the security of your wireless network. Selecting different method
will enable you to have different level of security. Please note that by using any
encryption, by which data packet is encrypted before transmission to prevent data packets
from being eavesdropped by unrelated people, there may be a significant degradation of
the data throughput on the wireless link.

Authentication Type: Open System or Shared Key/Shared Key/Open System
If Open System or Shared Key/Shared Key/Open System is selected, users will have to
Set WEP keys with an encryption either WEP64 or WEP128. Only the Open System can
set the encryption to None (Without any WEP Key protection mechanism)
•HEX: If you are using hexadecimal numbers (0-9, or A-F).
•ASCII: If you are using ASCII characters (case-sensitive).
•Ten hexadecimal digits or five ASCII characters are needed if 64-bit WEP is used
•26 hexadecimal digits or 13 ASCII characters are needed if 128-bit WEP is used
Authentication Type: WPA-PSK/WPA2-PSK
If WPA-PSK/WPA2-PSK is selected, users will have to select the Encryption from the
pull-down list, TKIP, AES or TKIP_AES and then enter a passphrase.
16

Authentication Type: Open System with 802.1x/WPA-RADIUS/WPA2-RADIUS
