Section 3 - Configuration
Beacon Interval
Beacons are packets sent by an access point to synchronize a wireless network. Specify a value in milliseconds. The
(25-500):
default (100) 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
(1-15): 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
Multimedia): over a Wi-Fi network.
Ack Time Out To effectively optimize throughput over long distance links, enter a value for Acknowledgement Time Out between 25 and
(2.4 GHZ, 64~200) 200 microseconds for 5 GHz or from 64 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.
Connection Limit:
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 field below. This feature allows the user to share the
wireless network traffic and the client using multiple APs. If this function is enabled, when the number of users exceeds
this value, the DAP-2553 will not allow clients to associate with the AP.
User Limit (0-64):
Set the maximum amount of users that are allowed access (0-64 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.
