When this value is set to twentyMhz, the AP works on 20MHz mode for both transmit and receive operations. dynamic: The 20/40 MHz operation is a dynamic feature in which the AP can receive packets from clients that use 20 MHz of bandwidth while transmitting a packet OR that use 40 MHz of bandwidth while transmitting a packet. Likewise, the AP can send packets either with a bandwidth of 20 or 40 MHz. When changing 802.11n channels, make changes in the following order: 1) Width (apRadioNCfgChannelWidth) 2) Offset (apRadioNCfgChannelOffset) 3) Channel (apRadioNCfgDesChannel)
