¾ 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.
¾ 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 modem router 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. This mechanism can provide you a
quiet communication channel by notifying other stations not to send packet for a period of
time. In most cases, keep its default value of 2347.
¾ 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. The countdown unit is measured
by the amounts of beacon frames received. When the modem router 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.
¾ Beacon Interval: Enter a value between 20-1000 milliseconds. The Beacon Interval value
indicates the frequency interval of the beacon. A beacon is a packet broadcast by the modem
router to synchronize the wireless network. The default value is 100.
¾ Transmit Power: This option will allow you to configure the wireless transmit power. High
transmit power will extend the wireless signal range of the device and make the signal
transmit more legible. Low transmit power with the smaller wireless signal range that will
decrease the probability of interrupt by other Wi-Fi device.
¾ WMM (Wi-Fi Multimedia): This function can guarantee the packets with high-priority
messages being transmitted preferentially. It is strongly recommended.
