Advanced Settings
This tab allows you to set the advanced wireless options. The options included are, Fragment
Threshold, RTS Threshold, Beacon Interval, and Preamble Type. You should not change these
parameters unless you know what effect the changes will have on the router.
•
Fragment Threshold: "Fragment Threshold" specifies the maximum size of a packet
during the fragmentation of data to be transmitted. If you set this value too low, it
will result in bad performance.
•
RTS Threshold: When the packet size is smaller then the RTS threshold, the wireless
router will not use the RTS/CTS mechanism to send this packet.
•
Beacon Interval: This is the interval of time that this wireless router broadcasts a
beacon. A Beacon is used to synchronize the wireless network.
•
Data Rate: The "Data Rate" is the rate that this access point uses to transmit data
packets. The access point will use the highest possible selected transmission rate to
transmit the data packets.
•
N Data Rate: The "Data Rate" is the rate that this access point uses to transmit data
packets for N compliant wireless nodes. Highest to lowest data rate can be fixed.
•
Channel Bandwidth: This is the range of frequencies that will be used.
•
Preamble Type: The "Long Preamble" can provide better wireless LAN compatibility
while the "Short Preamble" can provide better wireless LAN performance.
•
TX Power: The transmit power can be set to a bare minimum or maximum power for
better performance or power saving.
