Setting Up and Configuring the WRVS4400N Wireless-N Router Configuring Wireless Settings 5 • 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 802.11b 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. STEP 3 Click Save.
