D-Link DIR-605L User Manual
Section 3 - Configuration
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 flow is a problem, only a minor modification 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. 
(Delivery Traffic Indication Message) 
1
is the default setting. A DTIM 
is a countdown informing clients of the next window for listening 
to broadcast and multicast messages.
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. 
Auto is the default setting. Note: High network traffic 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 through put. 
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 traffic and collisions that occurs on the wireless network.
Select one of the following:
Mixed.802±11g.and.802±11b
- Select if you are using both 802.11b and 802.11g wireless clients.
802±11n.Only.
- Select only if all of your wireless clients are 802.11n.
Mixed.802±11n,.802±11b,.and.802±11g
- Select if you are using a mix of 802.11n, 11g, and 11b wireless clients.

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.
