Wifi.begin();
not working, i'm using it in function to wake nodemcu & connect to Wifi network.
here is my code......

void wifiConnect() {
WiFi.forceSleepWake();
WiFi.mode(WIFI_STA);
delay(10);
WiFi.begin();
Serial.print("Connecting to ");
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println();
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}

@Daemach commented on GitHub (May 6, 2019):

How can WiFi Manager turn into a complete wifi management solution? In a
perfect world it would combine the best of wifimulti and wifi manager, and
hit the following bullet points:

Attempt to connect to (potentially multiple) networks with provided
credentials
If that fails, attempt to connect to available open APs
If that fails, launch wifiManager
Or launch wifiManager on demand if a button is pressed.
In sleep mode, or if wifi is lost for some reason, the system should
try to reconnect in this order every time.

well the esp auto connects on its own already, so if thats not working something else is wrong with your board, try erasing flash and reload

I imagine very few people need wifi multi or auto connect to open, but there is no reason it needs to be in wm , it is easy to code those functions.

Would wifimulti conflict with the connection attempt that wifimanager is
trying to do?

if you call autoconnect after already connected then it just exits

Will it unload the webserver completely? I'm using the ESP32 with
asyncwebserver - a far more advanced and capable webserver that can support
mulltiple clients, websockets, etc. They both want to bind to port 80 so I
need to make sure wifimanager doesn't conflict.

you are probably going to have issues, either with webserver or dns server, I would not suggest it
