Don't use 

conectivityManager.getNetworkInfo(0) and getNetworkInfo(1).

Instead of that use

For WiFi

NetworkInfo conectivityManager = connectivity.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

For mobile networks(3g)

NetworkInfo conectivityManager = connectivity.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

Cause on Jelly Beans will make trouble hardcoding values like that.

Use SupplicantState

SupplicantState supState; 
wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
supState = wifiInfo.getSupplicantState();

See this answer in stackoverflow

If COMPLETED - All authentication completed.
