Esp-12e doesn’t reconnect to wifi automatically

Hi ,
I use esp8266-12e model. I have made smart plug through blynk on my smart phone. I have problem, when the esp8266 connection is broken the esp8266 doesn’t reconnect by itself and therefore I have to reset the esp8266. Does somebody know where the problem could be? Thank You.

That could be a lot of stuff. It could be a bad wifi connection or bad power supply in most cases. Can you tell us a little more about your setup? E.g. have you used capacitors to power the ESP? Because it’s very power hungry, up to 600mA I think.
