4.6 Wireless – Advanced Wireless Settings
This section provides AP's advanced wireless settings. These settings should be adjusted carefully. Any
improper settings will affect the AP's wireless performance.
Advanced Wireless
Wireless-A Settings
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.
