Issue : RaspberryPi 3 - Run the command "-ieee80211n --ht_capab '[HT40+] '" cause of the ER

[starsyiyi]

hi,
create_ap was run normal in raspberry pi 3 ,then i run the command "sudo create_ap --ieee80211n --ht_capab '[HT40+]' wlan0 eth0 rpi_ap 12345678" , create_ap can't setup AP , the following is hostapd trace. is issue ? how can i modify it? thx.

pi@raspberrypi:~/Downloads/create_ap $ sudo create_ap -n wlan0 rpi_ap 12345678 --hostapd-debug 1

Doing cleanup.. done

are you sure that there is no network manager running that can interfere the program. try to disable --ieee80211n and --ht-capab

colse it ,thx
