Section 3 - Configuration
Beacon Interval Beacons are packets sent by an access point to synchronize a wireless network. Specify a value in milliseconds. The default (100)
(40-500):
is recommended. Setting a higher beacon interval can help to save the power of wireless clients, while setting a lower one can
help a wireless client connect to an access point faster.
DTM Interval Select a Delivery Traffic Indication Message setting between 1 and 15. The default value is 1. DTIM is a countdown informing clients
(1-15): of the next window for listening to broadcast and multicast messages.
Transmit Power:
This setting determines the power level of the wireless transmission. Transmitting power can be adjusted to eliminate overlapping
of wireless area coverage between two access points where interference is a major concern. For example, if wireless coverage is
intended for half of the area, then select 50% as the option. Use the drop-down menu to select 100%, 50%, 25%, or 12.5%.

Ack Time Out To effectively optimize throughput over long distance links, enter a value for Acknowledgement Time Out between 25 and 200
(2.4 GHZ, 48~200) microseconds for 5 GHz or from 48 to 200 microseconds in the 2.4 GHz in the field provided.
or Ack Time Out
(5 GHZ, 25~200):
Short GI: Select Enable or Disable. Enabling a short guard interval can increase throughput. However, be aware that it can also increase
the error rate in some installations due to increased sensitivity to radio-frequency installations.
IGMP Snooping: Select Enable or Disable. Internet Group Management Protocol allows the AP to recognize IGMP queries and reports sent
between routers and an IGMP host (wireless STA). When IGMP snooping is enabled, the AP will forward multicast packets to an
IGMP host based on IGMP messages passing through the AP.
Multicast Rate: Adjust the multicast packet data rate here. The multicast rate is supported in AP mode, (2.4 GHZ and 5 GHZ) and WDS with AP
mode, including Multi-SSIDs.
Multicast Adjust the multicast packet data rate here. The multicast rate is supported in AP mode, and WDS with AP mode, including Multi-
Bandwidth SSIDs
