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 allow 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 mMAC 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.
