The issue was your single band cards do not store 5 GHz band regulatory information.

Right, do you have any other source for location or that you can make this implication from your devices? > The only exception in > Intel cards are JP and KR SKU's which are real regulatory domains. What makes them "real" BTW? > Just my two cents, probably didn't help to solve the problem, It certainly helps more understand your situation. I had no idea of MOW1 and MOW2. Can this be documented as part of the regulatory_hint() code changes which will be added?
