Channel Bandwidth—The 802.11n specification allows a coexisting 20/40 MHz
channel in addition to the legacy 20 MHz channel available with other modes. The 20/
40 MHz channel enables higher data rates but leaves fewer channels available for use
by other 2.4 GHz and 5 GHz devices.

by other 2.4 GHz and 5 GHz devices.
By default, when the radio mode includes 802.11n, the channel bandwidth is set to 20/
40 MHz to enable both channel widths. Set the field to 20 MHz to restrict the use of the
channel bandwidth to a 20 MHz channel.

Primary Channel (802.11n modes with 20/40 MHz bandwidth only)—A 40 MHz
channel can be considered to consist of two 20 MHz channels that are contiguous in the
frequency domain. These two 20 MHz channels are often referred to as the Primary and
Secondary channels. The Primary Channel is used for 802.11n clients that support only
a 20 MHz channel bandwidth and for legacy clients.
