Frame Burst
Enabling this option should provide your
network with greater performance, depending on the
manufacturer of your wireless products. To use the Frame
Burst option, select
Enable
. The default is
D±sable
.
Authent±cat±on Type
The default is set to
Auto
, which
allows either Open System or Shared Key authentication
to be used. With
Open System
authentication, the sender
and the recipient do NOT use a WEP key for authentication.
With
Shared Key
authentication, the sender and recipient
use a WEP key for authentication.
Bas±c Rate
The Basic Rate setting is not actually one rate
of transmission but a series of rates at which the Router
can transmit. The Router will advertise its Basic Rate to
the other wireless devices in your network, so they know
which rates will be used. The Router will also advertise that
it will automatically select the best rate for transmission.
The default setting is
Default
, when the Router can
transmit at all standard wireless rates. 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.
Transm±ss±on Rate
The rate of data transmission should
be set depending on the speed of your wireless network.
You can select from a range of transmission speeds, or you
can select
Auto
to have the Router automatically use the
fastest possible data rate and enable the Auto-Fallback
feature. Auto-Fallback will negotiate the best possible
connection speed between the Router and a wireless
client. The default value is
Auto
.
CTS Protect±on 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
The default value is
100
. Enter a value
between 20 and 1000 milliseconds. The Beacon Interval
value indicates the frequency interval of the beacon. 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
²
.
Fragmentat±on
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
2²46
.
RTS Threshold
Should you encounter inconsistent data
flow, only minor reduction of the default value,
2²4´
, 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
2²4´
.
