This Wireless > Advanced Wireless Settings screen is used
to set up the Router's advanced wireless functions . These
settings should only be adjusted by an expert administrator
as incorrect settings can reduce wireless performance .

Advanced Wireless
Authentication 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 .
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 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 1-2Mbps, 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 .
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 .
CTS Protection Mode CTS (Clear-To-Send) Protection
Mode should remain disabled unless you are having severe
problems with your Wireless-G products not being able
Wireless-G Broadband Router
Advanced Configuration
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 on the
Frame Burst option, select Enable . The default is Disable .
Beacon Interval The default value is 100 . 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 1 .
Fragmentation Threshold
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 .
AP Isolation 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 .
SecureEasySetup
This feature allows you to enable or
disable the SecureEasySetup feature . Select Disabled to
disable the feature and turn off the button's light . The
feature is Enabled by default .
