I've installed the network information plugin as per this tutorial into my Ionic 2 app:

[Ionic 2 | How to Work With Cordova Plugins](http://www.gajotres.net/ionic-2-how-to-use-cordova-plugins/)

However TypeScript won't compile because it can't find the reference for "Connection" in the states array lines. Any idea how to write the import statement for it as per Platform, Page etc?

**My class:** 

```
import {NavController, NavParams} from 'ionic-framework/ionic';
import {Page, ViewController, Platform, Alert, Modal, Events} from 'ionic-framework/ionic';
import {forwardRef} from 'angular2/core';
import {OnInit} from 'angular2/core';
import {Injectable} from 'angular2/core';
import {TodosService} from '../../services/TodosService';
import {MyTodosItem} from '../../pages/my-todos-item/my-todos-item';

@Page({
  templateUrl: 'build/pages/my-todos/my-todos.html'
})
class TodayPage {

  constructor(
    private platform: Platform,
    private nav: NavController,
    private _events: Events,
    private _todosService: TodosService) {
    this._platform = platform;
    this._isAndroid = platform.is('android');
  }

  ngOnInit() {
    this.getItems();
    this._events.subscribe('item:updated', () => {
      this.getItems();
    });

    this.checkNetwork();
  }

  checkNetwork() {
      this._platform.ready().then(() => {
          var networkState = navigator.connection.type;

          var states = {};
          states[Connection.UNKNOWN]  = 'Unknown connection';
          states[Connection.ETHERNET] = 'Ethernet connection';
          states[Connection.WIFI]     = 'WiFi connection';
          states[Connection.CELL_2G]  = 'Cell 2G connection';
          states[Connection.CELL_3G]  = 'Cell 3G connection';
          states[Connection.CELL_4G]  = 'Cell 4G connection';
          states[Connection.CELL]     = 'Cell generic connection';
          states[Connection.NONE]     = 'No network connection';

          alert(states[networkState]);
      });
  }
.. 
}

```

**Error is:**  

Cannot find name 'Connection'.
