Section 3 - Configuration
DTIM Interval (1-15): Select a Delivery Traffic Indication Message setting between 1 and 15. 1 is the default setting. DTIM is a countdown informing
clients 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%.
WMM (Wi-Fi WMM stands for Wi-Fi Multimedia. Enabling this feature will improve the user experience for audio and video applications over
Multimedia): a Wi-Fi network.
Ack Time Out (2.4 To effectively optimize throughput over long distance links enter a value for Acknowledgement Time Out between 25 and 200
microseconds for 5 GHz or from 48 to 200 microseconds in the 2.4 GHz in the field provided.
GHZ) or Ack Time Out
(5 GHZ):
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.
Select Enable or Disable. Internet Group Management Protocol allows the AP to recognize IGMP queries and reports sent
IGMP Snooping:
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 Bandwidth Adjust the multicast packet data rate here. The multicast rate is supported in AP mode, and WDS with AP mode, including Multi-

SSIDs
Maximum Multicast
Set the multicast packets maximum bandwidth pass through rate from the Ethernet interface to the DAP-3662.

HT20/40 Coexistence : Enable this option to reduce interference from other wireless networks in your area. If the channel width is operating at 40 MHz
and there is another wireless network's channel over-lapping and causing interference, the DAP-3662 will automatically change
to 20 MHz.
Transfer DHCP Offer to Enable to transfer the DHCP Offer to Unicast from LAN to WLAN, suggest to enable this function if stations number is larger than 30.
