within about 15 MHz of each side of the center frequency. As a result, an
802.11b signal overlaps with several adjacent channel frequencies. This
leaves you with only three channels (channels 1, 6, and 11 for the U.S.)
that you can use without causing interference between access points.
Bit rate
This allows you to set the bit rate in MBs. The bit rate is the speed at
which bits are transmitted over the medium.The user speed of the link is
lower due to medium sharing and various overhead. Select a value to lock
the card to a particular bit rate. If you specify auto, the driver will use all
bit rates to find an optimum rate.
RTS threshold
RTS/CTS adds a handshake before each packet transmission to make sure
that the channel is clear.This adds overhead, but increases performance in
case of hidden nodes or a large number of active nodes.This parameter
sets the size of the smallest packet for which the node sends RTS; a value
equal to the maximum packet size disables the mechanism. You may also
set this parameter to off.
Fragmentation threshold
Fragmentation allows to split an IP packet in a burst of smaller fragments
transmitted on the medium. In most cases this adds overhead, but in a very
noisy environment this reduces the error penalty and allow packets to get
through interference bursts.This parameter sets the maximum fragment
size.You may also set this to off to disable the mechanism.
TxPower
This allows you to set the transmit power of the radio. Setting a lower
value limits the range of the radio and reduces interference with other
access points.

Configuring Wireless Security Settings
Click on "Wireless Security"
The Wireless Security Settings allows you to control which wireless-
equipped devices may communicate with the router depending on their
MAC addresses. By default these MAC filters are disabled. If you turn MAC
Filters on, you should be sure and include the MAC address of the device
that you are using to communicate with. Otherwise, the machine that
you're using will lose its connection to the In-Car Router.
This page will show you all of the wireless devices currently attached to
the In-Car Router.
To enable MAC Filters, change the MAC Filters option to "on". And then
check the "Allowed" box next to the MAC addresses that you wish to
allow to join the network.
If you would like to have devices connect that are not currently attached
to the In-Car Router you may add them in the box.You can add multiple
devices by separating them with a space.
Select "Commit Changes" when you are finished.
