I am not sure how to detect if the connection is wifi or not but you can detect connection like this:

import { Network } from '@ionic-native/network';

declare var Connection;

constructor(public network: Network){
this.onDevice = this.platform.is('cordova');
this.network.onDisconnect().subscribe(() => {
      //something
      }
    });

    this.network.onConnect().subscribe(() => {
      //something 
      }
    });

isOnline(): boolean {
    if (this.onDevice && this.network.type) {
      return this.network.type !== Connection.NONE;
    } else {
      return navigator.onLine;
    }
  }

It’s ok but it works when you constructor is called.my scenario is different.
i want to call method when user does wifi/internet on/off.
the best u can understand in whatsapp send message to a friend (off your wifi) friend will not receive you message.after sending just on you wifi the message will be send now.

but I just gave you solution for that, look at my methods,

this.network.onDisconnect() and onConnect()

Thanks a lot it’s works.
Here is code:
Network.onConnect().subscribe(() => {
//something
console.log(“Connected”);

});

BUT it calls two times console.log(); why?

Network.onConnect() is use to detect if you have internet connection or not, it not detect wifi on/off
