Field Description

 

DTIM Interval

 

The Delivery Traffic Indication Message (DTIM) indicates the interval between

 

Broadcasts/Multicast transmissions. DTIM field is a countdown field informing

 

clients of the next window for listening to broadcast and multicast messages. When

 

the device 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.

 

(Default: 1, Range: 1-255)

 

 

 

Fragmentation Threshold

 

The fragmentation threshold 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

 

The RTS Threshold determines at what packet size beyond which the ready to

 

send/clear to send (RTS/CTS) mechanism is invoked. Should you encounter

 

inconsistent data flow, only minor reduction of the default value, 2346, is

 

recommended. If a network packet is smaller than the preset RTS Threshold size,

 

the RTS/CTS mechanism will not be enabled. The device sends Request to Send

 

(RTS) frames to a particular receiving station and negotiates the sending of a data

 

frame. After 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.
