I had some trouble with my d1 Mini that had a very hard time connecting to Wifi... got it running for a day or two, but then it lost connection and 50+ re-powers didn't help.
What did help was a cap across the power rails to the d1 Mini (+3V and GND) I just tried with a 1.000uF which fixed it (a smaller values should also do the trick).
Maybe this is just related to the d1 Mini I'm not sure, but it did the trick.
