Its not about trust its also about if it will logistically make sense, for example you simply cannot use HT40- on channel 11 if yuo don't have a channel 7. The NO_HT40- would indicate this to us so we don't bother. The example I give is lousy as its not something that would occur usually but with 5 GHz and regulatory rules changing things could be a bit different. > > johannes Luis
