802.11n Wireless Settings
When Radio Mode is set to 802.11n only, or to a mixed mode that includes 802.11n, configure the following options:
The options may vary depending on the type of appliance you are configuring.
| Radio Band | The channel width used by the radio. Select one of the available radio bands. | |
| Auto | Allows the appliance to automatically detect and set the optimal channel for wireless operation based on signal strength and integrity. This is the default setting. | |
| Standard 20MHz Channel |
Specifies that the 802.11n radio uses only the standard 20 MHz channel. When this option is selected, the Channel drop-down menu is displayed. Channel: The channel the access point uses for communication. By default, the channel is set to Auto. This allows the appliance to set the optimal channel based on signal strength and integrity. You can select a single channel within the range of your regulatory domain. Selecting a specific channel can also help the appliance avoid interference with other wireless networks in the area. |
|
| Wide 40MHz Channel |
Specifies that the 802.11n radio uses only the wide 40 MHz channel. When this option is selected, the Primary Channel and Secondary Channel drop-down menus are displayed. Primary Channel: The primary channel the access point uses for communication. By default, the primary channel is set to Auto. This allows the appliance to set the optimal channel based on signal strength and integrity. Secondary Channel: The configuration of this drop-down menu is controlled by your selection for the primary channel:

|
| Enable Short Guard Interval | Enable this to improve throughput in suitable environments. It applies only to 802.11ac/n mode. | |
| Enable Aggregation | Enables 802.11n frame aggregation, which combines multiple frames to reduce overhead and increase throughput. It applies only to 802.11ac/n mode. | |
| Enable WDS AP | Allows the WDS client to connect to this access point. | |
| SSID | Is filled with a default value of sonicwall- plus the last four characters of BSSID; for example, sonicwall-C587. The SSID can be changed to any alphanumeric value with a maximum of 32 characters. | |
The Enable Short Guard Interval and Enable Aggregation options can slightly improve throughput. They both function best in optimum network conditions where users have strong signals with little interference. In networks that experience less than optimum conditions (interference, weak signals, and so on), these options could introduce transmission errors that eliminate any efficiency gains in throughput.
