Select a Delivery Trac 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.
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 stands for Wi-Fi Multimedia. Enabling this feature will improve the user experience for audio and video applications over
a Wi-Fi network.
To eectively 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 eld provided.
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
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.
Select Enable or Disable. This is an option for load balancing. This determines whether to limit the number of users accessing
this device. The exact number is entered in the User Limit eld below. This feature allows the user to share the wireless network
trac and the client using multiple APs. If this function is enabled and when the number of users exceeds this value, or the
network utilization of this AP exceeds the percentage that has been specied, the DAP-2690 will not allow clients to associate
with the AP.
Set the maximum amount of users that are allowed access (zero to 64 users).To use this feature, the Connection Limit above must
be enabled. For most users, a limit of 10 is recommended. The default setting is 20.
Set the maximum utilization of this access point for service. The DAP-2690 will not allow any new clients to associate with the
AP if the utilization exceeds the value the user species. Select a utilization percentage between 100%, 80%, 60%, 40%, 20%,
or 0%. When this network utilization threshold is reached, the device will pause one minute to allow network congestion to
dissipate.
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.
