Use the n_chlwidth command to specify the 11n or 11ac channel width — 20 MHz, 40 MHz, 80 MHz, or Auto. This command is accessible from all radio contexts of the CLI.
20 | Specifies the channel width as 20 MHz |
40 | Specifies the channel width as 40 MHz |
80 | Specifies the channel width as 80 MHz (802.11ac radios only) |
auto | Specifies that the AP automatically selects the channel width depending upon how busy the extension channel is. The extension channel threshold is set via the n_pbthreshold command. |
The following example sets the channel width to 40 MHz:
