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.

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. Select
Shared Key
to
only use Shared Key authentication.
Transmission Rate
The rate of data transmission should
be set depending on the speed of your wireless network(s).
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
.
CTS Protection Mode
The Router will automatically
use CTS (Clear-To-Send) Protection Mode when your
Wireless-G products are experiencing severe problems and
are not 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. The default is
Auto
.
Beacon Interval
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(s). The default value is
100
.
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
.
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
.
