I have 4 nodemcu and 1 of them cant connect to WiFi. I have tried different codes but it still cant connect. Also I flashed it with newest nodemcu firmware but still cant connect. The other 3 works perfectly. What can I do about it and what can cause it?

I have noticed that sometimes It connects but after long time maybe after 2-3 minutes... And that is not a case with other nodemcus...

Sounds like it is just defective....

Yeah definitely it looks like it is defective. Also when I put it on NodeMcu base board. It becomes so hot. So I have turned it off immediately.
