As far as I understand the ieee80211ac variable states weather 80211ac is enabled or not, and thus I do not think that it should be changed based on the actual operating mode/channel width.
Regardless, how is it possible that the CS ended with being on VHT if hostap did not ask to use VHT in the first place?
Thanks in advance,
