When the Radio Mode field is configured for a mode that supports 802.11n only or a mixed mode that includes 802.11n, set following options:
The options you see could vary slightly, depending on the on the type of appliance being configured.
Sets the band for the 802.11n radio.
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 - 20 MHz Channel
Specifies that the 802.11n radio uses only the standard 20 MHz channel. When this option is selected, the Standard Channel drop-down menu is displayed.
Is set to Auto, by default, which 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 a channel can also help the appliance avoid interference with other wireless networks in the area.
Wide - 40 MHz 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.
Set to Auto by default, or you can specify a specific primary channel.
The configuration of this drop-down menu is controlled by your selection for the primary channel:
If the primary channel is set to Auto, the secondary channel is also set to Auto.
If the primary channel is set to a specific channel, the secondary channel is set to the optimum channel to avoid interference with the primary channel.
Enable Short Guard Interval
Enable this to have a higher Tx/Rx rate if supported. It applies only to 802.11ac/n mode.
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.
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.
