Not able to unsubscribe observables in ionic 3 app

I am using ionic 3 for my app,i am using cordova-plugin-network-information for internet connection detection event in android device, i am able to subscribe it, but not able to unsubscribe it.

I have tried rxjs, Subscription to unsubscribe from the observables, but didnt get expected result.

following is my code :

import {Subscription } from 'rxjs/Subscription';

private _netConnection : Subscription = new Subscription();

_netConnection = this.network.onConnect().subscribe(()=>{
          alert("connected");
})

_netConnection.unsubscribe();

But the enter code hereabove _netConnection.unsubscribe() is not working, as i am still getting the alert when connection is available.

Use take until

import { Subject } from 'rxjs';
import { takeUntil } from 'rxjs/operators';

private finalize = new Subject<void>();

this.network.onConnect().pipe(takeUntil(finalise)).subscribe(()=>{
  alert("connected");
  finalise.next();
});

I think u should write the _netConnection.unsubscribe() in setTimeout;

like this setTimeout(()=> _netConnection.unsubscribe());
