 The supported way to use WebREPL is by connecting to ESP8266 access point,
 but the daemon is also started on STA interface if it is active, so if your
 router is set up and works correctly, you may also use WebREPL while connected
 to your normal Internet access point (use the ESP8266 AP connection method
 if you face any issues).
