Configure Wireless Settings Section Advanced Wireless 46 Field Description N Transmission Rate The rate of data transmission should be set depending on the speed of your Wireless-N networking. Select from a range of transmission speeds, or select Auto to have the device automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback negotiates the best possible connection speed between the device and a wireless client. The factory default setting is Auto. Choose one of the following options for transmission rate: ƒ Auto (factory default) ƒ Use Legacy Rate ƒ 0: 6.5 or 13.5 Mbps ƒ 1: 13 or 27 Mbps ƒ 2: 19.5 or 40.5 Mbps ƒ 3: 26 or 54 Mbps ƒ 4: 39 or 81 Mbps ƒ 5: 52 or 108 Mbps ƒ 6: 58.5 or 121.5 Mbps ƒ 7: 65 or 135 Mbps ƒ 8: 13 or 27 Mbps ƒ 9: 26 or 54 Mbps ƒ 10: 39 or 81 Mbps ƒ 11: 52 or 108 Mbps ƒ 12: 78 or 162 Mbps ƒ 13: 104 or 216 Mbps ƒ 14:117 or 243 Mbps ƒ 15: 130 or 270 Mbps CTS Protection Mode CTS (Clear-To-Send) Protection Mode boosts the device's ability to catch all wireless transmissions, but can severely decrease performance. Select Auto to use this feature when needed, when the Wireless-N/G products are not able to transmit to the device in an environment with heavy 802.11b traffic. Select Disable to permanently disable this feature. Beacon Interval The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the device to synchronize the wireless network. (Default: 100 msec, Range: 20-1000) 4021196 Rev A
