D-Link AirPremier N Dual Band Exterior PoE Access Point
Using the Configuration Menu
WMM (Wi-Fi
Multimedia):
WMM stands for Wi-Fi Multimedia. Enabling this feature will improve
the user experience for audio and video applications over a Wi-Fi
network.
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.
This setting determines the power level of the wireless transmission.
Transmitting power can be adjusted to eliminate overlapping of wire-
less 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 pull-down
menu to select 100%, 50%, 25%, or 12.5%.
Transmit Power:
Ack Time Out (2.4 GHZ,
48~200) or Ack Time
Out (5 GHZ, 25~200):
To effectively optimize throughput over long distance links enter a
value for Acknowledgement Time Out between 25 and 200 micro-
seconds for 5 GHz or from 48 to 200 microseconds in the 2.4 GHz
in the eld provided.
DTIM Interval
(1-15):
Select a Delivery Traf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.
Beacons are packets sent by an access point to synchronize a
wireless network. Specify a value in milliseconds. The 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.
Beacon Interval
(25-500):
Select Enable or Disable. If the Ethernet connection between the
LAN and the AP is disconnected, enabling this feature will cause
the wireless segment associated with the AP to be disassociated
from the AP.
Link Integrity:
