Using the Configuration Menu
Advanced > Performance
The default Performance settings
are shown here.
Beacon Interval: Beacons are
packets sent by an Access Point
to synchronize a wireless net-
work. Specify a Beacon interval
value. Default (100) is recom-
mended.
RTS Threshold: This value
should remain at its default set-
ting of 2,432. If you encounter
inconsistent data flow, only minor
modifications to the value range
between 256 and 2,432 are rec-
ommended.
Fragmentation: This value should remain at its default setting of 2,346. If you
experience a high packet error rate, you may slightly increase your Fragmenta-
tion Threshold within the value range of 256 to 2,346. Setting the Fragmentation
Threshold too low may result in poor performance.
DTIM Interval (Beacon Rate): (Delivery Traffic Indication Message) Enter a
value between 1 and 255 (default is 3) for the Delivery Traffic Indication Mes-
sage (DTIM.) A DTIM is a countdown informing clients of the next window for
listening to broadcast and multicast messages.
Basic Rates: Default is 1-2Mbps. We recommend that you keep the setting at
default. If you lose connection at the TX rate, you will regain connection at the
basic rate. A lower Basic Rate will make reconnection easier. (If you are running
a wireless network consisting of all D-Link AirPlus and Air Premier products,
you may set a higher basic rate.)
TX Rates: Select the transmission rate for the network. The default rate is
1-2-5.5-11-22Mbps.
Preamble: Long Preamble is the default setting. (High traffic networks should
use the shorter preamble type.) The preamble defines the length of the CRC
block (Cyclic Redundancy Check is a common technique for detecting data
transmission errors) used in communication between the Access Point and the
roaming wireless Network adapters.
Authentication:
Open System - communicates the key across the network
Shared Key - devices must have identical WEP settings to communicate
Auto - automatically adjusts to the Authentication mode of the wireless client
