@skeal Sorry I just realized (I misunderstood your point)
Yes if using 160Mhz & DSF you will always be booted as required by law.
But with WiFi there are many misconceptions (& I struggle with them also).
Main One = Over Lapping SSID is not actually all that bad.
With electronics & wifi in particular hardly anything happens in real-time...
Things are cued, Even between competing/different SSID.
It's better to play nice & co-operate than just make noise into the neighboring channels.
When selecting a channel...
Yes try for none but, if the main channels are occupied, select the one with 3 different SSID instead of the one with 12 SSID.
Avoid the partial overlapping of adjacent channels (That is the more problematic interference AKA:Noise)
