protection mechanism will ensure that your Wireless-B devices will connect to Access
Point when many Wireless-G devices are present. However, performance of your
Wireless-G devices may decrease.
Basic Rates: The SNMP screen allows you to customize the Simple Network
Management. The default value is set to Default. Depending on the wireless mode
you have selected, a default set of supported data rates will be selected. The default
setting will ensure maximum compatibility with all devices. You may also choose to
enable all data rates by selecting ALL. For compatibility with former Wireless-B
devices, select 1-2Mbps.
Beacon Interval: This value indicates the frequency interval of the beacon.The default
value is 100. Enter a value between 20 and 1000 milliseconds. The Beacon Interval
value indicates the frequency interval of the beacon. A beacon is a packet broadcast
by the Access Point to synchronize the wireless network.
RTS Threshold:
This value should remain at its default setting of 2346.Should you
encounter inconsistent data flow, only minor reductions are recommended.
Fragmentation Threshold:
This value specifies the maximum size for a packet
before data is fragmented into multiple packets. It should remain at its default setting
of 2346. A smaller setting means smaller packets, which will create more packets for
each transmission. Only minor reductions of this value are recommended.
DTIM Interval: .The default value is 3. This value, between 1 and 255 milliseconds,
indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is
a countdown field informing clients of the next window for listening to broadcast and
multicast messages. When the Access Point has buffered broadcast or multicast
messages for associated clients, it sends the next DTIM with a DTIM Interval value.
Access Point Clients may hear the beacons and informed to receive the broadcast and
multicast messages.
