Advanced Wireless
Authentcaton 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.
Basc 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 (1-2Mbps, 5.5Mbps, 11Mbps,
18Mbps, and 24Mbps). Other options are
-2Mbps
, for
use with older wireless technology, and
All
, when the
Router can transmit at all 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.
Transmsson 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 Protecton Mode
CTS (Clear-To-Send) Protection
Mode should remain disabled unless you are having severe
problems with your Wireless-G products not being able
to transmit to the Router in an environment with heavy
802.11b traffic. This function boosts the Router’s ability
to catch all Wireless-G transmissions but will severely
decrease performance.
Frame Burst
Enabling this option should provide your
network with greater performance, depending on the
manufacturer of your wireless products. To turn off the
Frame Burst option, select
Dsable
. The default is
Enable
.
Beacon Interval
The default value is
00
. Enter a value
between 1 and 65,535 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 1 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
.
Fragmentaton 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,
234
, 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
234
.
AP Isolaton
This isolates all wireless clients and wireless
devices on your network from each other. Wireless devices
will be able to communicate with the Router but not with
each other. To use this function, select
On
. AP Isolation is
turned
Off
by default.
Secure Easy Setup
This feature allows you to enable or
disable the SecureEasySetup feature. Select Disable to
disable the feature and turn off the button’s light. The
feature is enabled by default.
Click the
Save Settngs
button to apply your changes, or
click the
Cancel Changes
button to cancel your changes.
Security > Firewall
The
Security > Firewall
screen is used to configure a firewall
that can filter out various types of unwanted traffic on the
Router’s local network.
