Many people have problems with using ESP8266 as WiFi-client due to none of the examples mentioning that you should use WIFI_STA if you only want the ESP8266 to act as a WiFi-client. Many WiFi-devices will randomly try to connect to the ESP8266 if used as STA+AP and complain about not being able to access the Internet or other devices on the network.
