◆ ACM — The admission control mode for the access category. When
enabled, clients are blocked from using the access category.
(Default: Disabled)
◆ AckPolicy — By default, all wireless data transmissions require the
sender to wait for an acknowledgement from the receiver. WMM allows
the acknowledgement wait time to be turned off for each Access
Category (AC) 0-3. Although this increases data throughput, it can also
result in a high number of errors when traffic levels are heavy.
(Default: Acknowledge)
MULTICAST-TO-
UNICAST CONVERTER
The Multicast-to-Unicast Converter section on the Wireless Settings
Advanced page allows you to enable multicast traffic conversion.
Converting multicast traffic to unicast before sending to wireless clients
allows a longer DTIM (Data Beacon Rate) interval to be set. A longer DTIM
interval prevents clients in power-save mode having to activate their radios
to receive the multicast data, which saves battery life.

The following items are displayed in this section on this page:
◆ Multicast-to-Unicast — Enables multicast traffic streams to be
converted to unicast traffic before delivery to wireless clients.
(Default: Disabled)
WLAN SECURITY
The Wireless-N Access Point/Repeater’s wireless interface is configured by
default as an “open system,” which broadcasts a beacon signal including
the configured SSID. Wireless clients with a configured SSID of “ANY” can
read the SSID from the beacon, and automatically set their SSID to allow
immediate connection to the wireless network.
To implement wireless network security, you have to employ one or both of
the following functions:
◆ Authentication — It must be verified that clients attempting to
connect to the network are authorized users.
◆ Traffic Encryption — Data passing between the unit and clients must
be protected from interception and eavesdropping.
