Dear Stanislaw:

	I find for cisco 1252 11N mode bandwith-20,
ieee80211_sta->ht_cap.cap & IEEE80211_HT_CAP_SUP_WIDTH_20_40
	was wrong in bss_info_changed, I have to check 20/40 MHZ based on
hw->conf.channel_type.

	All other APs will be ok, So may be it's AP IE's issue, But I think
mac80211 should also check hw->conf.channel_type
	before set ieee80211_sta->ht_cap.cap &
IEEE80211_HT_CAP_SUP_WIDTH_20_40.

Thank you!
