TRENDnet User's Guide Default Value: 100 milliseconds (range: 25-1000) • DTIM: A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. When the wireless router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Wireless clients detect the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. Valid settings are between 1 and 255. • Fragment Threshold: Wireless frames can be divided into smaller units (fragments) to improve performance in the presence of RF interference and at the limits of RF coverage. Fragmentation will occur when frame size in bytes is greater than the Fragmentation Threshold. This setting should remain at its default value of 2346 bytes. Setting the Fragmentation value too low may result in poor performance. • RTS Threshold - The Request To Send (RTS) function is part of the networking protocol. A wireless device that needs to send data will send a RTS before sending the data in question. The destination wireless device will send a response called Clear to Send (CTS). The RTS Threshold defines the smallest data packet size allowed to initiate the RTS/CTS function. Default Value: 2347 (range: 1-2347) • Short Preamble: Using a short (400ns) guard interval can increase throughput. However, it can also increase error rate in some installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best for your installation. • Xpress™ Technology: Is frame bursting technology built by Broadcom to improve wireless performance. It is recommended to leave this feature On. Wireless 5GHz Advanced settings Wireless > Advanced These settings are advanced options that can be configured to change advanced wireless broadcast specifications. It is recommended that these settings remain set to their default values unless you are knowledgeable about the effects of changing these values. Changing these settings incorrectly can degrade performance. © Copyright 2013 TRENDnet. All Rights Reserved.

The interval is the amount time between each beacon transmission.

A DTIM is a countdown informing clients of the next window for listening
to broadcast and multicast messages. When the wireless router has buffered
broadcast or multicast messages for associated clients, it sends the next DTIM
with a DTIM Interval value. Wireless clients detect the beacons and awaken to
receive the broadcast and multicast messages. The default value is 1. Valid
settings are between 1 and 255.

Wireless frames can be divided into smaller units
(fragments) to improve performance in the presence of RF interference and at
the limits of RF coverage. Fragmentation will occur when frame size in bytes is
greater than the Fragmentation Threshold. This setting should remain at its
