Hello Developers! I am trying to change channel type/width (HT20/HT40+) on the both STA and AP side in a simple system consists of only 1 STA and the AP. AP is started using hostapd under HT20 and STA thereafter connects to it using also HT20. But when AP changes its channel type to HT40+ using ieee80211_set_channel_type() and ath9k_hw_set_channel_regs(), it will lose connection to STA. The way I do channel type change coordination is: STA sends an action frame to AP, AP sends back ACK frame and changes its channel type; STA changes its channel type on receiving the ACK. I read about this solution (http://eznemegy.blog.hu/2008/12/14/using_rt2x00_wireless_driver_with_hostapd/fullcommentlist/1) of hacking into hostapd, which didn't work... It would be great if you more experienced would love to help me with this problem! Thanks in advance!!
