synchronization field.
Channel Width (802.11g+n, 802.11a+n and 802.11ac only): Choose between 20MHz, 40MHz or Auto.
Doubling channel bandwidth to 40 MHz is supported to enhance throughput. 80MHz is available for
selection in 802.11ac mode.
Channel: Select the appropriate
channel
from the drop-down menu to correspond with your network
settings.
Max Transmit Rate: The default is set to Auto. Available range is from 1 to 54Mbps. The rate of data
transmission should be set depending on the speed of the wireless network. Select from a range of
transmission speed or keep the default setting, Auto, to allow the Access Point to automatically use the
fastest rate possible. For 802.11n the selectable data rates range from MCS0 to MCS15, and for 802.11ac,
select data rates up to MCS9.
Transmit Power: On select AP models, the signal strength transmitted from the system can be selected by
Levels. Each level signifies a decrement of 1 dBm from the highest power. Level 1 is the actual highest
power, Level 2 is the highest power minus 1 dBm, so on and so forth.
Beacon Interval (ms): Enter a value between 20 and 1000 msec. The default value is 100 milliseconds. The
entered time means how often the beacon signal is transmitted between the access point and the
wireless network.
ACK Timeout: The time interval for waiting for the “acknowledgement (ACK) frame”. If the ACK is not
received within the interval then the packet will be re-transmitted. Higher ACK Timeout interval will
decrease the packet lost, but the throughput will be decreased/worsened.
Airtime Fairness: When set to “Fair Access”, this feature ensures all devices with different band
compatibilities have the same air time. When set to “Preferred Access”, N clients are prioritized. This
feature is ideal for networks with devices supporting different bands.
Packet Delay Threshold (ms): This is the Tx Queue flushing mechanism, which purpose is to drop packets
and immediately process others if the queue has been processed for more than x milliseconds. This is
disabled by default (=0).
Idle Timeout (s): Clients disconnects when inactivity reaches the configured amount of time in seconds,
where default = 300s.
Band Steering: When enabled, clients with 5GHz connectivity will be steered towards the 5GHz band to
reduce congestion in the 2.4GHz band. This is applicable only when the AP is set to 2.4GHz and 5GHz on
the 2 RF Cards. When “Aggressive” is checked, clients with 5GHz connectivity are forced to connect to the
5GHz band.
Interference Detection: When utilization of the current channel reaches the configured threshold (in %),
the AP switches to a different Channel.
Transmission Rate Threshold: The associated client will be kicked when transmission rate is lower than the
configured threshold. This ensures high connection speed for all associated clients.
WME Configuration: Access priority can be configured using with different parameters. CW Min:
Contention Window Minimum, CW Max: Contention Window Maximum, AIFS: Arbitration Inter Frame
Spacing, TXOP Limit: Transmission Opportunity Limit.
