A DTIM is a countdown informing clients of the next window for listening to broadcast and
multicast messages. When the wireless Access Point has buffered broadcast or multicast
messages for associated clients, it sends the next DTIM with a DTIM Interval value. Wireless
clients detect the beacons and awaken to receive the broadcast and multicast messages. The
default value is 1. Valid settings are between 1 and 255.
WMM Enable
Enabling WMM can help control latency and jitter when transmitting multimedia content over
a wireless connection.
WDS Enable
When WDS is enabled, this access point functions as a wireless repeater and is able to
wirelessly communicate with other APs via WDS links. Note that WDS is incompatible with
WPA -- both features cannot be used at the same time. A WDS link is bidirectional; so this AP
must know the MAC Address (creates the WDS link) of the other AP, and the other AP must
have a WDS link back to this AP. Make sure the APs are configured with the same channel
number.
Short GI
Using a short (400ns) guard interval can increase throughput. However, it can also increase
error rate in some installations, due to increased sensitivity to radio-frequency reflections.
Select the option that works best for your installation.
WDS AP MAC Address
Specifies one-half of the WDS link. The other AP must also have the MAC address of this AP
to create the WDS link back to this AP. Enter a MAC address for each of the other APs that
you want to connect with WDS.
