and the code in ts file is-

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { Network } from '@ionic-native/network/ngx';

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  constructor(public navCtrl: NavController,private network: Network)
  {
    this.network.onConnect().subscribe(() => {
      console.log('network connected!');
      setTimeout(() =>
      {
        if (this.network.type === 'wifi')
        {
          console.log('we got a wifi connection, woohoo!');
        }
      }, 3000);
    });



  }
