D-Link DIR-400 - Advanced Wireless

51D-Link DIR-400 User Manual
Section 3 - Conguration
Set the transmit power of the antennas.
Beacons are packets sent by an Access Point to synchronize
a wireless network. Specify a value. 100 is the default setting
and is recommended.
This value should remain at its default setting of 2346. If
inconsistent data ow is a problem, only a minor modication
should be made.
The fragmentation threshold, which is specified in bytes,
determines whether packets will be fragmented. Packets
exceeding the 2346 byte setting will be fragmented before
transmission. 2346 is the default setting.
A DTIM (Delivery Trafc Indication Message) is a countdown(Delivery Trafc Indication Message) is a countdownis a countdown
informing clients of the next window for listening to broadcast and multicast messages. 1 is the default setting.
Select Short or Long Preamble. The Preamble denes 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. Auto is the default setting. Note: High network trafc areas should use the shorter preamble type.
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. 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 occur frequently.
Always: CTS will always be used to make sure the wireless LAN is clear before sending data. Auto: CTS will monitor the
wireless network and automatically decide whether to implement CTS based on the amount of trafc and collisions that
occurs on the wireless network.

This window allows you to change the behavior of the 802.11g wireless radio from the standard settings. Please be aware
that any changes to the factory default settings may adversely affect the behavior of your network.
