802.11n Wireless Router
Advanced
This tab allows you to set the advanced wireless options. You should not change these parameters unless you
know what effect the changes will have on the router.
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: Interval of time the wireless router broadcasts a beacon, 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.
CTS Protection: It is recommended to enable the protection mechanism. This mechanism can decrease the rate
of data collision between 802.11b and 802.11g wireless stations. When the protection mode is enabled, the
throughput of the AP will be a little lower due to a lot of frame-network that is transmitted.
TX Power: This can be set to a bare minimum or maximum power.
