It specifies the wireless channel bandwidth of the AP. This parameter can be set if
the AP works in 11 b/g/n, 11ac, 11a/n mode and Lock Channel is not selected.
−
20MHz: It indicates that the AP can use only 20 MHz channel bandwidth.
−
40MHz: It indicates that the AP can use only 40 MHz channel bandwidth.
−
20/40MHz: It indicates that the AP automatically adjusts its channel
bandwidth to 20 MHz or 40 MHz according to the ambient environment.
−
80MHz: Only available for 5 GHz. It indicates that the AP can use only 80 MHz
channel bandwidth.
−
160MHz: Only available for 5 GHz. It indicates that the AP can use only 160
MHz channel bandwidth.
−
20/40/80/160MHz: Only available for 5 GHz. It indicates that the AP
automatically adjusts its channel bandwidth to 20 MHz, 40 MHz, 80 MHz, or
160 MHz according to the ambient environment.
It is used to determine the operating frequency band of this device when it uses the
40 MHz channel bandwidth in 11n mode.
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 Expansion Channel cannot be changed.
It specifies the transmit power of the AP.
A greater transmit power of the AP offers broader network coverage. You can
slightly reduce the transmit power to improve the wireless network performance
and security.
It specifies whether the current transmit power settings of the AP can be changed.
If it is selected, the settings cannot be changed.
A preamble is a group of bits located at the beginning of a packet to enable a
receiver of the packet to perform synchronization and prepare for receiving data.
By default, the Long Preamble option is selected for compatibility with old network
adapters installed on wireless clients. To achieve better synchronization
performance of networks, you can select the Short Preamble option.
Short Guard Interval.
There is a delay on the receiving side due to multipath and other factors during the
wireless signal transmission in space. If the subsequent data block is transmitted
too quickly, it will interfere with the previous data block, and the short guard
interval can be used to circumvent this interference. Short GI helps to increase the
wireless throughput by 10%.
Suppress Broadcast
Probe Response
By default, wireless devices keep sending Probe Request packets that include the
SSID field to scan their nearby wireless networks. After receiving such packets, this
device determines whether the wireless devices are allowed to access its wireless
networks based on the packets and responds using the Probe Response packets
(including all Beacon frame parameters), which consumes a lot of wireless
resources.
After this function is enabled, this device does not respond to the requests without
an SSID, saving wireless resources.
