Description
It specifies the interval for transmitting the Beacon frame.
The Beacon frame is transmitted at the specified interval to announce the
presence of a wireless network. Generally, a smaller interval enables
wireless devices to connect to the AP more quickly, while a larger interval
ensures higher data transmission speed for the AP.
It specifies the threshold of a fragment. Unit of this parameter is byte.
Fragmenting is a process that divides a frame into several fragments, which
are transmitted and acknowledged separately. If the size of a frame exceeds
this threshold, the frame is fragmented.
In an environment of high error rate, you can reduce the threshold to
enable the AP to resend only the fragments that have not been sent
successfully, so as to increase the frame throughput.
In an environment without interference, you can increase the threshold to
reduce the number of acknowledgement times, so as to increase the frame
throughput.
It specifies the frame length threshold for triggering the RTS/CTS
mechanism. Unit of this parameter is byte.
If a frame exceeds this threshold, the RTS/CTS mechanism is triggered to
reduce conflicts.
Set the RTS threshold based on the actual situation. An excessively small
value increases the RTS frame transmission frequency and bandwidth
requirement. A higher RTS frame transmission frequency enables a WiFi
network to recover from conflicts quicker. For a WiFi network with high user
density, you can reduce this threshold for reducing conflicts. The RTS
mechanism requires some network bandwidth. Therefore, it is triggered
only when frames exceed this threshold.
It specifies the interval for transmitting the Delivery Traffic Indication
Message (DTIM) frame. Unit of this parameter is Beacon.
A countdown starts from this value. The AP transmits broadcast and
multicast frames in its cache only when the countdown reaches zero.
For example, if DTIM Interval is set to 1, the AP transmits all cached frames
after each beacon frame is transmitted.
Set a minimum strength of received signals acceptable to the AP. If the
strength of the signals transmitted by a wireless device is weaker than this
threshold, the wireless device cannot connect to the AP.
If there are multiple APs, an appropriate Minimum RSSI Threshold ensures
that wireless devices can connect to the AP' WiFi networks with strong
signals.
It specifies whether to enable the Prioritize 5 GHz function. If the function is
enabled, devices supporting 5 GHz WiFi network connects to AP's 5 GHz
