I was afraid you'd say that.Everything related to wifi is out of my control.
But on the Brighter side... I'm embarrassed to admit, I just noticed the following:
DFS State: Idle Time elapsed: 0h 0m 0s Channel cleared for radar: none
It's Tucked right between the: Wireless 5GHz (info) & the Device Chart
Found via: System Log >Wireless Log
That easily shows if the router actually thought it detected radar & dropped 160MHz & all 5GHz clients.
Hopefully this will assist others as well.
