5.6. Advanced
This tab allows you to set the advanced wireless options. The options included are
Authentication Type, 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: This 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 than the RTS threshold, the wireless
router will not use the RTS/CTS mechanism to send this packet.
Beacon Interval: is the interval of time that this wireless router broadcasts a beacon. A
Beacon is used to synchronize the wireless network.
DTIM Period: Enter a value between 1 and 255 for the Delivery Traffic Indication
Message (DTIM). A DTIM is a countdown informing clients of the next window for
listening to broadcast and multicast messages
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.
