I got the same problem!! It's annoying me for a long time (about 2 moths).
I had tried all What I can change , eg. sdk version 2.0, 2.2, 3.0, and an Arduino ino (https://github.com/techiesms/ESP8266-Sm ... config.ino
Thank goodness, finally I found this post , just when I began to doubt my wifi router (maybe some incompatible
Netgear WNDR4300v2 ).
Saw the keyword " 2.4G and 5G ", after turning 5G off ...... it works!!
I dont know much about wifi Spec, maybe the 5G signal from same router does interference on smart config process?
So to say, the tech of "smart config" is not strong enough to work reliable. We must to implement "config by hand" to ensure our product can work anywhere.
