do you wifi is 2.4G, not use by 5.8G.
you can use your mobile phone work as wifi hot spot, let your KC868-A128 board connect it for a testing.

do you only want use KC868-A128 board work with digital input and digital output using wifi? if YES, i can test it to compile.

Small update 

I also have an A64 board, this board does not have this problem. 
Can it be the ESP32 chip that breaks i am going to check the voltage input but it must be fine 24v 25A power supply


also can you test the with wifi

[admin]

ok, i will test with wifi by esphome.

[admin]

Tested with KC868-A128. here are two yaml file for ethernet and wifi.
   

[S.Krans]

So the esp32 a64 card is stable but the a128 card not can this be a failing esp32


I am going to swap the eth cable 
Also i am checking the imput voltage

[S.Krans]

So update wifi is stable but lan not problem with ethernet chip??

Code:

# Example configuration entry
ethernet:
  type: LAN8720
  mdc_pin: GPIO23
  mdio_pin: GPIO18
  clk_mode: GPIO17_OUT
  phy_addr: 0

  # Optional manual IP
  #manual_ip:
  #  static_ip: 20.20.20.183
  #  gateway: 20.20.20.1
  #  subnet: 255.255.255.0
  #  dns1: 8.8.8.8
