Advanced wireless 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.

•Beacon Interval: A beacon is a management frame used in wireless networks that transmitted periodically to announce the presence and provide information about the router’s wireless network. The interval is the amount time between each beacon transmission.

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

TEW-691GR

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: 2346 (range: 256-2346)

•TX Burst: Allows the wireless Router to deliver better throughput in the same period and environment in order to increase speed.

•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.

•Multicast-to-Unicast:Some applications require multicast communication (also called IP multicast which is the delivery of information to a specific group of computers or devices in a single transmission) typically used in media streaming applications. Enable this feature when using application that requires multicast traffic.

Wireless Distribution System (WDS)

Wireless > Basic

WDS or Wireless Distribution System allows your router to establish a wireless bridge connection to another access point. To use this feature the access point you want to connect has to also support WDS mode.

1.Log into your router management page (see “Access your router management page” on page 24).

2.Select Enable in the Wirelesss Distribution System section.
