Hi @TimothyFran , Thanks for the PR. If you look at this part of the code, WiFi.autoReconnect is disabled before _connect to avoid any rogue connection to STA while the device checks for it during initial setup.

I'd like to know more about the issue you faced. A better solution will be to modify the _connect function to have a third boolean parameter by which we can control when we need the auto-reconnect functionality.

The problem I'm facing is that if the Wi-Fi connection is lost it is not automatically reconnected once it is available again.

I'll update my changes to add a Boolean parameter as you suggested
