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
