Beacon Interval Enter a value between 1 and 65,535
milliseconds. The Beacon Interval value indicates the
frequency interval of the beacon. A beacon is a packet
broadcast by the Valet to synchronize the wireless
network. The default value is 100.
DTIM Interval This value, between 1 and 255, 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 Valet has buffered
broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Its clients
hear the beacons and awaken to receive the broadcast
and multicast messages. The default value is 1.
Fragmentation Threshold This value specifies the
maximum size for a packet before data is fragmented
into multiple packets. If you experience a high packet
error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low
may result in poor network performance. Only minor
reduction of the default value is recommended. In most
cases, it should remain at its default value of 2346.
RTS Threshold Should you encounter inconsistent
data flow, only minor reduction of the default value, 2347,
is recommended. If a network packet is smaller than
the preset RTS threshold size, the RTS/CTS mechanism
will not be enabled. The Valet sends Request to Send
(RTS) frames to a particular receiving station and
negotiates the sending of a data frame. Af ter receiving
an RTS, the wireless station responds with a Clear to
Send (CTS) frame to acknowledge the right to begin
transmission. The RTS Threshold value should remain at
its default value of 2347.
