20 MHz or 40 MHz according to the ambient environment.
Extension Channel It specifies the wireless extension channel of the AP.
Lock Channel
It is used to lock the channel settings of the AP. If this parameter is selected,
channel settings including Country/Region, Network Mode, Channel, Channel
Bandwidth, and Extension Channel cannot be changed.
Transmit Power
It specifies the transmit power of the AP. The default value is 8 dBm. If the AP has a
higher transmit power, its WiFi coverage is wider. However, reasonably decreasing
the transmit power will improve the AP’s WiFi network performance and security.
Lock Power
It specifies whether the current transmit power settings of the AP can be changed.
If you tick this box, the current transmit power could not be changed.
Preamble
It specifies a group of bits located at the beginning of a packet, according to which
the receiver of the packet can perform synchronization and prepare for receiving
data. By default, the Long Preamble option is selected for compatibility with old
network adopters installed on wireless devices. To achieve better synchronization
performance of networks, you can select the Short Preamble option.
Isolate SSID
It specifies whether to isolate the wireless devices connected to the AP with
different SSIDs.
−
Disable: It specifies the Isolate SSID function is disabled, so that the wireless
devices connected to the AP with different SSIDs can communicate with each
other.
−
Enable: It specifies the Isolate SSID function is enabled, so that the wireless
devices connected to the AP with different SSID cannot communicate with
each other, which improves WiFi network security.
Short GI
It specifies short guard interval. Propagation delay of WiFi signal will happen to the
receiving port during transmission. If the following data block is sent too fast, it will
interfere the previous data block. A short guard interval can be used to circumvent
this interference. Enabling the short GI function can yield a 10% improvement in
data throughput. By default, this function is enabled.
