I was just trying to set up a rt2800 AP but hostapd was unable to set the channel when configuring 11n. rt2800 doesn't support HT40 yet, that's why it doesn't set IEEE80211_HT_CAP_SUP_WIDTH_20_40 and cfg80211 refuses to set the channel when the device doesn't support IEEE80211_HT_CAP_SUP_WIDTH_20_40 even if a HT20 only channel should be set. Did I miss anything or should it be allowed to set a HT20 channel on a HT capable device that doesn't allow HT40?
