DTIM Interval
DTIM (Delivery Traffic Indication Message) is a countdown
informing clients of the next window for listening to broadcast
and multicast messages. The default setting is 3.
Preamble Type Select Short or Long Preamble. The Preamble defines the
length of the CRC block (Cyclic Redundancy Check is a
common technique for detecting data transmission errors) for
communication between the wireless router and the roaming
wireless network adapters.
Note: High network traffic
areas should use the shorter preamble type.
SSID Broadcast
Choose Enabled to broadcast the SSID across the network.
All devices on a network must share the same SSID (Service
Set Identifier) to establish communication. Choose Disabled
if you do not wish to broadcast the SSID over the network.
802.11g Only Mode Select this mode to restrict your network to only those devices
that employ the 802.11g standard. Enabling this mode will
ensure that you maintain the highest connectivity rate,
unhampered by any connection to an 802.11b device.
CTS Mode CTS (Clear To Send) is a function used to minimize collisions
among wireless devices on a wireless local area network
(LAN). CTS will make sure the wireless network is clear
before a wireless client attempts to send wireless data.
Enabling CTS will add overhead and may lower wireless
throughput.
Auto- CTS will monitor the wireless network and
automatically decide whether to implement CTS based on the
amount of traffic and collisions that occurs on the wireless
network.
Always- CTS will always be used to make sure the wireless
LAN is clear before sending data.
None- CTS is typically used in a pure 802.11g environment. If
CTS is set to “None” in a mixed mode environment populated
by 802.11b clients, wireless collisions may
