Advanced Wireless
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 Valet but not 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 this option,
keep the default, Enabled. Otherwise, select Disabled.
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.
Basic Rate The Basic Rate setting is not actually one rate
of transmission but a series of rates at which the Valet can
transmit. The Valet will advertise its Basic Rate to the other
wireless devices in your network, so they know which
rates will be used. The Valet 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). Other options are 1-2Mbps, for use with older
wireless technology, and All, when the Valet can transmit
at all wireless rates. The Basic Rate is not the actual rate of
data transmission. If you want to specify the Valet’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 Valet automatically use the
fastest possible data rate and enable the Auto-Fallback
feature. Auto-Fallback will negotiate the best possible
connection speed between the Valet and a wireless client.
The default 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 Valet
automatically use the fastest possible data rate and enable
the Auto-Fallback feature. Auto-Fallback will negotiate the
best possible connection speed between the Valet and a
wireless client. The default is Auto.
CTS Protection Mode The Valet will automatically
use CTS (Clear-To-Send) Protection Mode when your
Wireless-N and Wireless-G products are experiencing
severe problems and are not able to transmit to the
Valet in an environment with heavy 802.11b traffic. This
function boosts the Valet’s ability to catch all Wireless-N
and 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 Valet to synchronize the wireless
network. 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 Valet 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 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 Valet 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.

Security > Firewall
The Firewall screen is used to configure a firewall that can
filter out various types of unwanted traffic on the Valet’s
local network.
