TOPIC: Reconnect Problem

Reconnect Problem 2 weeks 1 day ago #3858

I'm having a problem. When the internet network drops, either by the carrier or wifi, wemos d1 disconnects and stops sending the information. When the internet connection is reestablished, wemos will not connect again, unless I reset the card. How can I solve this? I need the card to automatically reconnect if there is a change in the network. Thank you.
Note: I am using the blog code "ESP8266 WiFi DHT22 humidity sensor (EasyIoT Cloud REST API V1)"

If the internet connection does not fall, it stays stable, I can turn on and off the wemos that it connects normal to the network.
