If you just want to know whether the device has an active internet connection, you can use e.g. isConnected from React Native's NetInfo:

import { NetInfo } from "react-native";

NetInfo.isConnected.addEventListener(
  "connectionChange",
  hasInternetConnection =>
    console.debug("hasInternetConnection:", hasInternetConnection)
);

However I'm not sure how to find out how good the connection is.
