cptskippy. • 3 yr. ago. In the US, 2.4Ghz is usually distributed between channels 1, 6 and 11 at 20Mhz widths so that there's no overlap between adjacent channels. The trouble with 40Mhz is that it will overlap with adjacent channels regardless of where you put it. The one exception is if you have two APs on channels 1 and 11, the 40mhz width
In our example from 5530 we subtract 20MHz once, which gives us value 5510MHz, and to 5550 we add twice 20MHz (+40MHz) which gives us value 5590MHz. The obtained values are the initial value of the channel frequency equal to 5510MHz and the final value of the channel frequency equal to 5590MHz (5510MHz-5590MHz).
This means the 11 channels have to squeeze into the 100 MHz available, and in the end, overlap. Channels 1, 6, and 11, however, are far enough from each other on the 2.4GHz band that they have sufficient space between their channel centers and do not overlap. While choosing channels 1, 6, or 11 will mean you have to share the channels with
Bonding channels increases throughput, which can improve performance. Thus, the difference between 20 MHz and 40 MHz is throughput. 40 MHz has higher throughput than 20 MHz thanks to channel bonding. …. While 40 Mhz might have higher throughput than 20 Mhz, it also reduces the number of non-overlapping channels.

And the help info at the bottom says: "Enable 20/40 MHz Coexistence - Disabling this option allows your 2.4GHz wireless to stay in supporting the max speed. Enabling this option may reduce the max speed of your 2
Non-contiguous bandwidths can improve the function of the 160 MHz spectrum. 160 MHz is divided into two 80 MHz bandwidths. Occupying two out of the four contiguous Wi-Fi channels and bonding the channels is more realistic than using a single 160 MHz bandwidth. Channel bonding allows you to select both a low band and high band channel, while

Double Wide Channel – 40MHz Support 802.11n supports 20 or 40 MHz wide channels 40 MHz wide channels recommended only for 5 GHz Consists of a primary channel and a secondary channel also referred to as extension channel Second channel must be adjacent Can be above or below primary Protection provided for 20 MHz wide client use
But there can also be more channel interference from your neighbors. Most people use the widest channel width provided. For WiFi 4 (802.11 n), that’s two channels or 40 MHz. For WiFi 5 (802.11 ac), that’s 4 channels or 80 MHz, but only in the 5 GHz band. Each 20 MHz allows a maximum bit rate of about 100 Mbps.
