For netgear routers, the channel width is determined by the “up to” speed.

Up to 4803Mbps = 160MHz channel width, and thus it will only list channels where it has access to a contiguous 160MHz in your region.
Up to 2400Mbps= 80MHz channel width.
Up to 1200Mbps = 40MHz channel width.
Up to 600Mbps = 20MHz channel width.

As you pick wider channel width settings, certain channels will be omitted from the list.

The overall available channels is related to the regelortory region for the router.
For example, in the US, the following channels are available, and for the 802.11ax routers, they are not really doing 80+80 type setups to deal with gaps.
