  • If you are disconnected you cannot connect to the webservice. So when your connection to the webservice fails you know you have no connection. Some code of how you connect to the webservice would be useful. – KIKO Software Jan 30 '18 at 09:24
  • You could ping a random site. If you get a response then you're online, else you're not. Search for 'angular4 ping' there's several sources you can use. – rrd Jan 30 '18 at 09:24
