I experienced many wifi connection problems with the wifi AP at home. At work, no problem. I suspect that ESP8266 may have problems connecting to certain channels or AP.
A friend of mine got exactly the same problem with its home wifi AP. We both worked with ESP01. Maybe there is a new silicon revision now?
ps: a colleague told me that this problem could potentially be seen if the quartz oscillator of the chip is slightly de-rated. A little temperature increase and the center frequency of the module is misaligned with wifi channels. I did not verify this assumption but this seems to make sense in some ways.
