This section provides AP’s advanced wireless settings. These settings should be adjusted carefully. Any improper 
settings will affect the AP’s wireless performance. 
 

Authentication Type:  

Open System: This is default setting, those wireless clients that NOT use a WEP key for authentication.  
Shared Key: This option means the wireless clients use a WEP key for authentication. Shared Key is only available 
if the WEP option is implemented. 

 
Transmission Rate: The data transmission rate should be set depending on the speed of your wireless network. You 
can select a proper transmission speeds to fit your wireless clients requirement, or you can select Auto (Default) to 
have the AP automatically adjust one the fastest and suitable data rate to fit network status at the time. Usually this 
function can be named Auto-Fallback feature. Auto-Fallback will treat one best connection rate between the AP and a 
wireless client. The default value is Auto (Default). 
 
Transmission Power: This option provides the AP’s RFoutput power adjustment. To minimize the possibility of 
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.
