• @MaBe Nope, I haven't saved the credentials at any point in time nor I have a .wificfg in the storage.
    @allObjects I see what you are getting at, but my question is different. I am unable to understand how WiFi is getting reconnected after I reboot my router (and keep the NodeMCU on). I have not defined that it should reconnect to WiFi happen when WiFi is disconnected, and still I see it connects to WiFi flawlessly when the router comes up.
