IMG-1312-D User’s Manual
the frequency interval of the beacon. A beacon is a packet
broadcast by the AP to synchronize the wireless network. 50 is
recommended in poor connection.
DTIM Interval
The default value is 1. This value, between 1 and 255
milliseconds, indicates the interval of the Delivery Traffic
Indication Message (DTIM). A DTIM field is a countdown field
informing clients of the next window for listening to broadcast and
multicast messages. When the AP has buffered broadcast or
multicast messages for associated clients, it sends the next DTIM
with a DTIM Interval value. Its clients hear the beacons and
awaken to receive the broadcast and multicast messages.
Fragmentation
Threshold
This value should remain at its default setting of 2346. The
range is 256-2346 bytes. It specifies the maximum size for a
packet before data is fragmented into multiple packets. If you
experience a high packet error rate, you may slightly increase the
Fragmentation Threshold. Setting the Fragmentation Threshold
too low may result in poor network performance. Only minor
modifications of this value are recommended.
RTS Threshold
This value should remain at its default setting of 2347. The
range is 0-2347 bytes. Should you encounter inconsistent data
flow, only minor modifications are recommended. If a network
packet is smaller than the preset RTS threshold size, the
RTS/CTS mechanism will not be enabled. The AP sends
Request to Send (RTS) frames to a particular receiving station
and negotiates the sending of a data frame. After receiving an
RTS, the wireless station responds with a Clear to Send (CTS)
frame to acknowledge the right to begin transmission.
Xmit Power
This value ranges from 1 - 100 percent, default value is 100
percent. A safe increase of up to 60 percent would be suitable
for most users. Higher power settings are not recommended for
users due to excess heat generated by the radio chipset, which
can affect the life of the AP.
Wireless Network
Mode
If you have IEEE802.11g and IEEE802.11b devices in your
network, then keep the default setting, BG Mixed mode . If you
have only IEEE802.11g devices, select G Mode . If you would
like to limit your network to only IEEE802.11b devices, then
select B Mode .
