Configuring the WAP4410N Wireless-N Access Point Wireless 6 • Channel Bandwidth-Select the channel bandwidth for Wireless-N connections. If you choose 20MHz, only the 20MHz channel is used. If you choose 40MHz, Wireless-N connections use the 40MHz channel, but Wireless-B and Wireless-G connections still use the 20MHz channel. The default is 20MHz. • Guard Interval-Select a guard interval for Wireless-N connections. The three options are Auto, Short (400ns) and Long (800ns). The default is Auto. • CTS Protection Mode-Keep the default setting, Auto, so the access point can use this feature as needed when the Wireless-N/G products are not able to transmit to the access point in an environment with heavy 802.11b traffic. Select Disabled if you want to permanently disable this feature. This mode boosts the ability of the access point to catch all wireless transmissions, but severely decrease performance. • Beacon Interval-Enter the frequency interval of the beacon (20-1000). A beacon is a packet broadcast by the access point to keep the network synchronized. A beacon includes the wireless networks service area, the access point 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-Enter a Delivery Traffic Indication Message (DTIM) interval (1-255). This value indicates how often the access point sends out a DTIM. Lower settings result in more efficient networking, while preventing your computer from dropping into power-saving sleep mode. Higher settings allow your computer to enter the sleep mode, thus saving power, but interferes with wireless transmissions. The default is 1 ms. • RTS Threshold-Enter an RTS threshold (1-2347). This setting determines how large a packet can be before the access point coordinates transmission and reception to ensure efficient communication. This value should remain at its default setting of 2347. If you encounter inconsistent data flow, only minor modifications are recommended. • Fragmentation Threshold-Enter the preferred setting between 256 and 2346. Normally, this can be left at the default value of 2346. WAP4410N Wireless-N Access Point with Power Over Internet 47
