Fragmentation
Threshold The threshold (number of bytes) for the fragmentation boundary for
directed messages. It is the maximum data fragment size that can
be sent. Enter an even number between
256 and 2346 .
Beacon Interval When a wirelessly networked device sends a beacon, it includes
with it a beacon interval. This specifies the time period before the
device sends the beacon again. The interval tells receiving devices
on the network how long they can wait in low-power mode before
waking up to handle the beacon. This value can be set from 30ms to
1000ms. A high value helps save current consumption of the access
point.
DTIM Delivery Traffic Indication Message (DTIM) is the time period after
which broadcast and multicast packets are transmitted to mobile
clients in the Active Power Management mode. A high DTIM value
can cause clients to lose connectivity with the network. This value
can be set from 1 to 100.
Output Power Set the output power of the NWA in this field. If there is a high
density of APs in an area, decrease the output power to reduce
interference with other APs. Select one of the following
100%(Full
Power) , 50% , 25% , 12.5% or Minimum . See the product
specifications for more information on your NWA’s output power.
Note: Reducing the output power also reduces the NWA’s
effective broadcast radius.
Rates Configuration This section controls the data rates permitted for clients.
For each Rate , select an option from the Configuration list. The
options are:
• Basic (1~11 Mbps only): Clients can always connect to the
access point at this speed.
• Optional : Clients can connect to the access point at this speed,
when permitted to do so by the AP.
• Disabled : Clients cannot connect to the access point at this
speed.
Select SSID Profile An SSID profile is the set of parameters relating to one of the
NWA’s BSSs. The SSID (Service Set IDentifier) identifies the
Service Set with which a wireless station is associated. Wireless
stations associating with the access point (AP) must have the same
SSID.
Note: If you are configuring the NWA from a computer
connected to the wireless LAN and you change the
NWA’s SSID or security settings, you will lose your
wireless connection when you press Apply to confirm.
You must then change the wireless settings of your
computer to match the NWA’s new settings.
Index Select the check box to activate an SSID profile.
Active Select the check box to enable the bridge connection. Otherwise,
clear the check box to disable it.
