Getting the current network type

Anytime after the deviceready event fires, you can query the plugin for the status of the current network connection by querying navigator.connection.type:

var networkType = navigator.connection.type;
switch (networkType) {
  case Connection.UNKNOWN:
  console.log ("Unknown connection."); break;
  case Connection.ETHERNET:
  console.log ("Ethernet connection."); break;
  case Connection.WIFI:
  console.log ("Wi-Fi connection."); break;
  case Connection.CELL_2G:
  console.log ( "Cellular (2G) connection."); break;
  case Connection.CELL_3G:
  console.log ( "Cellular (3G) connection."); break;
  case Connection.CELL_4G:
  console.log ( "Cellular (4G) connection."); break;
  case Connection.CELL:
  console.log ( "Cellular connection."); break;
  case Connection.NONE:
  console.log ( "No network connection."); break;
}

If you executed the preceding code on a typical mobile device, you'd probably either see some variation of the Cellular connection or the Wi-Fi...
