Missing 5Ghz Channels
Like many others, I cannot figure out how to get the 40Mhz and 80Mhz 5Ghz channels to be available. My current settings are shown below including a screenshot showing that only the 20Mhz channels are available. How do I make the 40Mhz and 80Mhz channels available? Had to "reply to my own message and individually attach the screen shots as they do not show in the original message... :-(
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.

Does this help?
How about disabling Smart Connect?
- Will try your suggestion tomorrow. Smart Connect NOT enabled. Thanks
You've got it setup correct.
When you're using 160hz wide channels, you select and channel and get channel overlap that covers the 160hz wide.
You won't "see" the 160hz wide broadcast unless you use a wifi scanner like insidder or winfi.

Thanks for the "channel tutorial". I understand now that (for instance) the 160 Mhz is not really one channel but a combination of channels to make up the 160 Mhz. That's why you have fewer to choose from the wider you go. Thanks!
