Note
If a GWN76XX is not being discovered or the pair icon is grey color, make sure that it is not being paired
with another GWN76XX Access Point acting as Master Controller.

Channel Width: Choose the Channel Width, note that wide
channel will give better speed/throughput, and narrow channel will
have less interference. 20Mhz is suggested in very high-density
environment.

40MHz Channel Location: Configure the 40MHz channel location
when using 20MHz/40MHz in Channel Width, users can set it to be
Secondary below Primary, Primary below Secondary or Auto.

Channel: Select Auto, or a specified channel, default is Auto. Note
that the proposed channels depend on Country Settings under
System SettingsMaintenance.

Enable Short Guard Interval: Check to activate this option to
increase throughput.

Radio Power: Set the Radio Power, it can be Low, Medium or High.

Enable Minimum RSSI: Configures whether to enable/disable
Minimum RSSI function.

Custom Wireless Power(dBm): allows users to set a custom
wireless power for both 5GHz/2.4GHz band, the value of this field
must be between 1 and 31.

Allow Legacy Devices(802.11b): Check to support 802.11b devices
to connect the AP in 802.11n/g mode.

Dynamic Channel Assignment: Once enabled, AP will try to
allocate and move the best channel during operation, unlike Auto
Channel Selection (ACS) which scan and assign channel when Wi-
Fi interface goes up for one time.

Transmit Power Control: TPC algorithm runs every 10 minutes. AP
acquires the RSSI information of the neighbor by wireless scanning
and establishes the neighbor table. The algorithm requires that there
must be at least 3 neighbor APs with RSSI larger than -70dbm.
Otherwise, power will not be adjusted.

Coverage Hole Detection: CHD enables AP to decide whether to
increase the AP power by the current SNR and SNR threshold of the
connected clients.
