eavesdropping by unauthorized wireless users, suggest to decrease the transmission power with a needed by your
wireless environment. By drop down menu, you can select the appropriate level, Full (Default), Half, Quarter,
Eighth, or Min. The default is Full (Default).
Antenna Select: This option provides antenna setting for which one you would like to set as TX/RX antenna. Using
Diversity setting is proposed.
ACK Timeout: The Acknowledgement Timeout means from remote to local data transmission, one parameter to
control both acknowledging action to guaranty those packets have already be received. Usually, for short distance,
keep default setting is proposed. If there is long distance application, have minor increased with this parameter will be
proposed.
Beacon Interval: The Beacon Interval value indicates the frequency interval of the beacon. Enter a value between 20
and 1000. A beacon is a packet broadcast by the AP to synchronize the wireless network. The default value is 100.
DTIM Interval: This value 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 AP
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.
Beacon interval: The data transmitted on your wireless network that keeps the network synchronized.
DTIM: A message included in data packets that can increase wireless efficiency.
Fragmentation: Breaking a packet into smaller units when transmitting over a network medium that cannot support
the original size of the packet.
RTS Threshold: Using this setting can regulate your wireless network if you experience any inconsistent data flow
situation, only by minor adjustment of the default value, the default value 2346 is recommended. The RTS/CTS
mechanism will not be enabled if your wireless network packet less than RTS threshold value. The AP 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 keep at its default value of 2346.
