N Transmission Rate

Wireless

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:

Auto (factory default) Use Legacy Rate

0:6.5 or 13.5 Mbps

1:13 or 27 Mbps

2:19.5 or 40.5 Mbps

3:26 or 54 Mbps

4:39 or 81 Mbps

5:52 or 108 Mbps

6:58.5 or 121.5 Mbps

7:65 or 135 Mbps

8:13 or 27 Mbps

9:26 or 54 Mbps

10:39 or 81 Mbps

11:52 or 108 Mbps

12:78 or 162 Mbps

13:104 or 216 Mbps 14:117 or 243 Mbps

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)
