Try this,

public boolean isInternetOn(Context ctx) {
        this.mContext = ctx;
        ConnectivityManager Connect_Manager = (ConnectivityManager) mContext
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        State connected = NetworkInfo.State.CONNECTED;
        State connecting = NetworkInfo.State.CONNECTING;
        State disconnected = NetworkInfo.State.DISCONNECTED;

        State info0 = Connect_Manager.getNetworkInfo(0).getState();
        State info1 = Connect_Manager.getNetworkInfo(1).getState();

        // ARE WE CONNECTED TO THE NET
        if (info0 == connected || info0 == connecting || info1 == connecting
                || info1 == connected) {

            Log.d("Internet", "Connected");
            return true;
        } else if (info0 == disconnected || info1 == disconnected) {
            Log.d("Internet", "DisConnected");
            return false;
        }
        return false;
    }

Can you remove this info0 == connecting || info1 == connecting condition from the "if" and then check? — Andro Selva, Jul 26 '12 at 05:18

See below code

    public static boolean checkConnection(Context context) {

    final ConnectivityManager mConnectivityManager = (ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE);

    final NetworkInfo netInfo = mConnectivityManager.getActiveNetworkInfo();
    if (netInfo != null && netInfo.isConnectedOrConnecting()) {
        return true;
    } else
        return false;
}

So, its connected to wi-fi network but no internet access. Right?

Try to ping 8.8.8.8 or google.com to know whether there is internet access. This will help you.
