performance.

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, click 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.
If you are not sure how to use this option, keep the
default, Enabled.
Authentication Type. The default is
set to Auto, which allows either Open System or
Shared Key authentication to be used. Select Shared
Key if you only want to use 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.
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 setting 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 setting is Auto.
CTS Protection Mode. CTS
(Clear-To-Send) Protection Mode’s default setting is
Auto. The Router will automatically use CTS
Protection Mode when your Wireless-N and 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-N and Wireless-G
transmissions but will severely decrease
performance.
Beacon Interval . Enter a value between 1-65535 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. 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.
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. In most
cases, keep its default value of 2347.
