• CTS Protection Mode—CTS (Clear-To-Send) Protection Mode function
boosts the router's ability to catch all wireless transmissions, but severely
decrease performance. Keep the default setting, Auto, so the router can use
this feature as needed, when the Wireless-N/G products are not able to
transmit to the router in an environment with heavy 802. 1 1b traffic. Select
Disabled if you want to permanently disable this feature.
• Beacon Interval— Indicates the frequency interval of the beacon. A beacon
is a packet broadcast by the router to keep the network synchronized. A
beacon includes the wireless networks service area, the router address, the
Broadcast destination addresses, a time stamp, Delivery Traffic Indicator
Maps, and the Traffic Indicator Message (TIM). The default is 100 ms.
• DTIM Interval—Indicates how often the router sends out a Delivery Traffic
Indication Message (DTIM). Lower settings result in more efficient
networking, while preventing your personal computer from dropping into
power-saving sleep mode. Higher settings allow your personal computer to
enter sleep mode, thus saving power, but interferes with wireless
transmissions. The default is 1 ms.
• RTS Threshold— Determines how large a packet can be before the router
coordinates transmission and reception to ensure efficient communication.
This value should remain at its default setting of 2346. If you encounter
inconsistent data flow, only minor modifications are recommended.
