Playing around with channel selection on my AP One Mini, I accidentally selected channel 165, and ended up with a 20MHz channel in the 5GHz spectrum.
I then scanned my neighborhood using an app (WiFi Explorer Lite).
Although there are plenty of 5GHz stations around with consumer routers, it seems like nobody is on channel 165.
Although it’s only 20MHz wide, in some cases a smaller width channel that is totally clear will outperform a more congested channel.
Am I just lucky? Or is channel 165 kind of a “secret” channel here in the USA?
Edit to add: I think the reason channel 165 may be lightly used is that most people want 40 or 80MHz wide channels in the 5GHz specturm, but when you do that, channel 165 is not used: see this picture which shows how 165 is not covered when using 40 or 80MHz channels in 5GHz:
