Problem Description

I have a similar issue as #1020, using ESP12E board. When I am declaring certain pins, using attachInterrupts() and setting up Access Point WiFi in the same void setup() the wifi stops working. I have tested out that if I only declare pins D0, D1, D2, D3, D4, A0 and set up WiFi without the interrupts it does work. Please seen my setup code below!
I have tried detachInterrupt(), but it did not work.

Does anyone have the same problem? Is there a solution to this problem?

Thank you in advance.

You mention D numbering, but your code uses GPIO numbering, and they're not the same.
E.g.: on a nodemcu board, D1 is GPIO5 and GPIO1 is TX.
Your code is using GPIO0-4, and some of those are not allowed for user applications. I suggest you study the board pinout and how it connects to the ESP12 pinout.
Closing as user error.
