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 client s detect the beacons and awaken to
receive the broadcast and multicast messag es. 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 pres ence of RF interference and at
the limits of RF coverage. Fragmentation will o ccur 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 sen d a RTS before sending
the data in question. The destination wireless device will send a response called
Clear to Send (CTS). The RTS Threshold define s 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 o ption that works best for
your installation.
• Xpress™ Technology: Is frame bursting technology built by Broadcom to improve
wireless performance. It is recommended t o leave this feature On.
Wireless > Advanced
These settings are advanced options that can be configured to change advanced
wireless broadcast specifications. It is reco mmended 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 tha t
transmitted periodically to announce the presence and provide information
about the router’s wireless network. The inter val 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

with a DTIM Interval value. Wireless client s detect the beacons and awaken to
receive the broadcast and multicast messag es. The default value is 1. Valid
