Basic Rate: The Basic Rate setting is not one, but a series of rates at which the Router can transmit. (The Basic Rate is not the actual rate of data transmission. If you want to specify the Router's rate of data transmission, configure the Transmission Rate setting.) Transmission Rate: The rate of data transmission should be set depending on the speed of your wireless network. CTS Protection Mode: CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having severe problems with your wireless products not being able to transmit to the Router in an environment with heavy latency wireless traffic. This function boosts the Router's ability to catch all wireless transmissions but will severely decrease performance. Beacon Interval: A beacon is a packet broadcast by the Router to synchronize the wireless network. DTIM Interval: This value, between 3 and 255, 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 Router 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. The default value is 3. Fragmentation Threshold: This value 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 reduction of the default value is recommended. In most cases, it should remain at its default value of 2346. RTS Threshold: Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router 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. The RTS Threshold value should remain at its default value of 2347. Click Apply to save the setting. 32

Basic Rate:
The Basic Rate setting is not one, but a series of rates at which the Router
can transmit. (The Basic Rate is not the actual rate of data transmission. If you want to
specify the Router’s rate of data transmission, configure the Transmission Rate setting.)
Transmission Rate:
The rate of data transmission should be set depending on the
speed of your wireless network.
CTS Protection Mode:
CTS (Clear-To-Send) Protection Mode should remain disabled
unless you are having severe problems with your wireless products not being able to
transmit to the Router in an environment with heavy latency wireless traffic. This
function boosts the Router’s ability to catch all wireless transmissions but will severely
decrease performance.
Beacon Interval:
A beacon is a packet broadcast by the Router to synchronize the
wireless network.
DTIM Interval:
This value, between 3 and 255, 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 Router
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. The default value is
3
.
Fragmentation Threshold:
This value 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 reduction of the
default value is recommended. In most cases, it should remain at its default value of
2346
.
RTS Threshold:
Should you encounter inconsistent data flow, only minor reduction of
the default value,
2347
, is recommended. If a network packet is smaller than the preset
RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router 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. The RTS
Threshold value should remain at its default value of
