Fragmentation A threshold, specified in bytes, that determines whether packets
Threshold will be fragmented and at what size. On an 802.11 WLAN,
packets that exceed the fragmentation threshold are fragmented,
i.e., split into, smaller units suitable for the circuit size. Packets
smaller than the specified fragmentation threshold value are not
fragmented. Enter a value between 256 and 2346. If you
experience a high packet error rate, try to slightly increase your
Fragmentation Threshold. The value should remain at its default
setting of 2346. Setting the Fragmentation Threshold too low
may result in poor performance.
RTS Threshold Request to Send, when set in bytes, specifies the packet size
beyond which the WLAN Card invokes its RTS/CTS mechanism.
Packets that exceed the specified RTS threshold trigger the
RTS/CTS mechanism. The NIC transmits smaller packet without
using RTS/CTS. The default setting of 2347 (maximum length)
disables RTS Threshold.
DTIM Interval Delivery Traffic Indication Message (DTIM) is also known as
Beacon Rate. The entry range is a value between 1 and 65535.
A DTIM is a countdown variable that informs clients of the next
window for listening to broadcast and multicast messages.
When the AP has buffered broadcast or multicast messages for
associated clients, it sends the next DTIM with a DTIM Interval
value. AP Clients hear the beacons and awaken to receive the
broadcast and multicast messages. The default is 1.
Beacon Interval The amount of time between beacon transmissions in
milliseconds. The default is 100 ms and the acceptable range is
1 – 65535. The beacon transmissions identify the presence of an
access point. By default, network devices passively scan all RF
channels listening for beacons coming from access points.
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).
Maximum The maximum number of clients allowed to connect to the router.

54g Mode Set the mode to 54g Auto for the widest compatibility. Select the
mode to 54g Performance for the fastest performance among 54g
certified equipment. Set the mode to 54g LRS if you are
experiencing difficulty with legacy 802.11b equipment.
Select Auto mode for greatest compatibility. Select
Performance mode for the fastest performance among 54g
certified equipment. Select LRS mode if you are experiencing
difficulty with legacy 802.11b equipment. If this does not work,
you may also try 802.11b only mode.
54g Protection In Auto mode, the router will use RTS/CTS to improve 802.11g
performance in mixed 802.11g/802.11b networks.
Turning protection Off will maximize 802.11g throughput under
most conditions.
Preamble Type Short preamble is intended for applications where maximum
throughput is desired but it does not work with legacy equipment.
Long preamble works with the current 1 and 2 Mbit/s DSSS
specification as described in IEEE Std 802.11-1999
Transmit Power Set the power output (by percentage) as desired.
