 If you need to set a timeout so the ESP doesn't hang waiting to be configured, for instance after a power failure, you can add

 Debug is enabled by default on Serial. To disable add before autoConnect
 ```

+### Custom IP Configuration
+This will set your captive portal to a specific IP should you need/want such a feature. Add the following snippet before `autoConnect()`
+```
+//set custom ip for portal
