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.
