Option Description
Band The new amendment allows IEEE 802.11g units to fall back to
speeds of 11 Mbps, so IEEE 802.11b and IEEE 802.11g devices
can coexist in the same network. The two standards apply to the
2.4 GHz frequency band. IEEE 802.11g creates data-rate parity
at 2.4 GHz with the IEEE 802.11a standard, which has a 54 Mbps
rate at 5 GHz. (IEEE 802.11a has other differences compared to
IEEE 802.11b or g, such as offering more channels.)
Channel Drop-down menu that allows selection of a specific channel.
Auto Channel
Timer (min) Auto channel scan timer in minutes (0 to disable)
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, 5.5Mbps, 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)
