Setting up AP no longer sets default IP address

[zhiquanyeo]

In earlier versions of the Arduino Core, the following code would result in IP Address: 192.168.42.1 getting printed to Serial. However, with 3.6.2, I get IP Address: (IP unset) instead.

#include <WiFi.h>

void setup() {
  // put your setup code here, to run once:
  while (!Serial) {}

  Serial.begin(115200);

  Serial.println("Creating AP");
  WiFi.softAP("test-network", "test-password");
  delay(1000);

  Serial.print("IP Address: ");
  Serial.println(WiFi.softAPIP());
}

void loop() {
  // put your main code here, to run repeatedly:

}

To work around this, I had to add the following before the WiFi.softAP(...) call:

  // Workaround
  IPAddress ip {192, 168, 42, 1};
  IPAddress subnet {255, 255, 255, 0};
  WiFi.softAPConfig(ip, ip, subnet);

Was this an expected change?

No, this was a regression. #1862 seems to wipe the AP config, need to investigate.
