Using the Configuration Utility (continued)
Advanced > Performance
The default Performance
settings are shown here.
Beacon Interval: Beacons
are packets sent by an Access
Point to synchronize a wireless
network. Specify a Beacon
interval value. Default (100) is
recommended.
RTS Threshold: This value
should remain at its default
setting of 2,432. If you encoun-
ter inconsistent data flow, only
minor modifications to the value
range between 256 and 2,432
are recommended.
Fragmentation: This value should remain at its default setting of 2,346. If you expe-
rience a high packet error rate, you may slightly increase your Fragmentation 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 Message (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.
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 Re-
dundancy 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
SSID Broadcast: (Service Set Identifier) Enable or Disable (default) the broadcast
of the SSID name across the network. SSID is a name that identifies a wireless
network. All devices on a network must use the same SSID to establish communica-
tion.
