Setting Up the Access Point
Configuring Advanced Settings
After receiving an RTS frame, the device sends a CTS (clear to send)
frame to notify the sending device that it can start sending data.
(Default is 2347)
• Fragmentation Length : Configures the minimum packet size that
can be fragmented when passing through the access point. Fragmen-
tation of the PDUs (Package Data Unit) can increase the reliability of
transmissions because it increases the probability of a successful
transmission due to smaller frame size. If there is significant interfer-
ence present, or collisions due to high network utilization, try setting
the fragment size to send smaller fragments. This speeds the retrans-
mission of smaller frames. It is more efficient to set the fragment size
larger if very little or no interference is present because it requires
overhead to send multiple frames. If set to 2346, this feature is
disabled. Range: 256-2346, even numbers. (Default is 2346)
• Beacon Interval : The rate at which beacon frames are transmitted
from the access point. The beacon frames allow wireless clients and
devices to maintain contact with the access point. They may also carry
power-management information. Range: 20-1000 ms (Default is 100)
• DTIM Interval : The Delivery Traffic Indication Message (DTIM)
interval helps keep marginal clients connected by sending “wake up”
frames. Range: 1- 255 (Default is 1).
• Preamble Type: Sets the length of the signal preamble used at the
start of a data transmission. Using a short preamble can increase data
throughput on the access point, but requires all connected devices be
able to support a short preamble. (Default is Long)
–
Long : Sets the preamble to long. Using a long preamble ensures
the access point can support all 802.11b and 802.11g devices
– Short : Sets the preamble according to the capability of devices
that are currently associated. Uses a short preamble if all associ-
ated devices can support it, otherwise a long preamble is used.

There are two Apply buttons on the Advanced Settings page: the first is for
the advanced wireless settings and the second is for the SNMP community
settings. Make sure you click the correct
Apply button for the settings that
you want to save.
