| Make sure that the IP addresses provided to ''WiFi.config()'' are proper IP addresses. In my experiments, it happened that instead of a gateway IP address, the code submitted the subnet mask 255.255.255.0. This is considered as an error by ''WiFi.config()'' and if the function is not inserted in the error-checking loop shown above, the ESP8266 will activate the DHCP client and you will try desperately to figure out what has happened!!! | Make sure that the IP addresses provided to ''WiFi.config()'' are proper IP addresses.
