You can use the class WifiManager and through the method setWifiEnabled can enable and disable wifi, official documentation can be found here.

To do this you must add the permission in the manifest of your application.

On your Androidmanifest.xml add the following permission:

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

and in its programme to implement:

   WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
   wifi.setWifiEnabled(false); //desabilita
   wifi.setWifiEnabled(true); //habilita
