Advanced Configuration
18
Simultaneous Dual-Band Wireless-N Gigabit Router
with each other. To use this function, select
Enabled
. AP
Isolation is disabled by default.
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, keep the default,
Enabled
.
Authentication Type
The default is
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.
Basic Rate
The Basic Rate setting is not actually one rate
of transmission 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.) 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
, for transmission at all standard
wireless rates (1-2 Mbps, 5.5 Mbps, 11 Mbps, 18 Mbps, and
24 Mbps).
Transmission 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
.
N Transmission Rate
The rate of data transmission
should be set depending on the speed of your Wireless-N
networking. 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 is
Auto
.
Transmission Power
Select the appropriate level of
transmission power:
High
,
Medium
, or
Low
. In most
cases, keep the default,
High
.
CTS Protection Mode
The Router automatically
uses CTS (Clear-To-Send) Protection Mode when your
Wireless-N and Wireless-G devices are experiencing severe
problems and are not able to transmit to the Router in an
environment with heavy 802.11b traffic. This option boosts
the Router’s ability to catch all Wireless-N and Wireless-G
transmissions but severely decreases performance. To use
this option, keep the default,
Auto
. To disable this option,
select
Disabled
.
Beacon Interval
A beacon is a packet broadcast by the
Router to synchronize the wireless network. Enter a value
between 20 and 1000 milliseconds. The Beacon Interval
value indicates the frequency interval of the beacon. The
default value is
100
.
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
.
