54g™ Rate Drop-down menu that specifies the following fixed
rates:
Auto: Default. Uses the 11 Mbps data rate when
possible but drops to lower rates when necessary.
1 Mbps, 2Mbps, 5Mbps, or 11Mbps fixed rates. The
appropriate setting is dependent on signal strength.
Multicast Rate Setting multicast packet transmit rate
Basic Rate Setting basic transmit rate
Fragmentation Threshold A threshold, specified in bytes, that determines
whether packets 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), also
known as Beacon Rate. The entry range is a value
between 1 and 65535. A DTIM is a countdown
informing 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.
Each beacon transmission identifies the presence of
an access point. By default, radio NICs passively
scan all RF channels and listen for beacons coming
from access points to find a suitable access point.
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).
The entered value is represented in ms. Default is
100. Acceptable entry range is 1 to 0xffff (65535)
