It seems position of "ifconfig wlan0 up" matters 1) It can't be before iwconfig which will result in "SET failed on device wlan0 ; Device or resource busy". 2) _Before_ "essid" and "key" settings. "ap auto channel auto" MUST NOT BE SET. 3) _After_ "essid" and "key". Ensure all iwconfig settings comes before "ifconfig". So, it seems "ifconfig" must be done as the last stage.
