DTIM Period
To coordinate the network, the Modem Router sends out “beacon frames,”
normally one every tenth of a second. A beacon frame can include a Delivery
Traffic Indication Message (DTIM). Clients in power-saving mode deactivate
their receivers except to receive beacon frames containing DTIMs, which
tell them if there is data for them to receive. The default DTIM period is 1,
meaning that every beacon frame contains a DTIM; a setting of 2 puts a DTIM
into every other beacon frame, and so on. Setting DTIM higher helps clients
conserve power but can reduce throughput.
Privacy Separator
Communication between wireless stations must go through the Modem
Router. The Privacy Separator function prevents any wireless station from ac-
cessing any other. You can enable this function for better security.
Mac Filter
The MAC Filter is a powerful security feature that allows you to specify which
computers are allowed on the network. Any computer attempting to access
the network that is not specified in the filter list will be denied access. Default
setting is “Allow All” which permits all wireless clients with the correct SSID
and security settings to join the network.
Click the “Registration List” button to display the MAC Address Filter List.
This is a list of wireless devices that will not be allowed to join the wireless
network.
To put a device on the list, you must know its Medium Access Control (MAC)
address, often called its MAC or LAN MAC. This normally can be found on a
label on the bottom or back of the device, or on the network interface card in
a desktop computer.
You can enter MAC addresses manually, or use the Wireless Client MAC List
(see below). When the desired MAC addresses are entered, click “Apply” to
