should only be adjusted by an expert administrator as incorrect
settings can reduce wireless performance.

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.
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 20-1000 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, 2346,
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 2346.

settings as described here and click the Save Settings button
