Grandstream Networks GWN76 Series User Manual page 86

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 Dynamically assigned by RRM.
Note : Dynamically assigned by RRM activates 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. This is not supported on GWN7610.
• Enable DFS Channel: If enabled, you can use band2 and band3 channels when "Auto" channel is
selected. Note: It will not take effect on GWN7600/GWN7602/GWN7610.
• Radio Power: Set the Radio Power, it can be Low, Medium, or High or Custom or Dynamically
assigned by RRM or Auto.
Note : Dynamically assigned by RRM activates TPC and CHD:
• Transmit Power Control: TPC algorithm runs every 10 minutes. AP acquires the RSSI information of the
2.4G & 5G neighbor by wireless scanning and establishes the neighbor table. The algorithm requires that there must
Configuration 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.
• 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.
• Enable Short Guard Interval: Check to activate this option to increase throughput.
• Allow Legacy Devices (802.11b): Check to support 802.11b devices to connect the AP in 802.11n/g
mode. (2.4GHz setting)
• Enable Minimum RSSI: Check to enable RSSI function, this will lead the AP to disconnect users
below the configured threshold in Minimum RSSI (dBm).
• Minimum RSSI: Enter the minimum RSSI value in dBm. If the signal value is lower than the
configured minimum value, the client will be disconnected. The input range is from "-94" or "-1".
• Minimum Access Rate Limit: Specify whether to limit the minimum access rate for clients. When
enabled, it will help to eliminate the legacy connection which slow the total performance of the Wi-Fi
network. Range from 1 to 54 Mbps.
SECURITY
Rogue AP
The GWN Access Points offer the ability to prevent malicious intrusion to the network and increases the wireless security
access of clients when introducing Rogue AP detection. The detected APs will be listed with all the details under Detected
section for further intervention. This feature is not supported in GWN7610.
In the figure below is the configuration page in order to enable the Rogue AP detection and we can set the trusted Aps on the
network.
