Try the below function to check your internet connection:

    public static boolean isInternetConnected(Context mContext) {

        try {
            ConnectivityManager connect = null;
            connect = (ConnectivityManager) mContext
                    .getSystemService(Context.CONNECTIVITY_SERVICE);

            if (connect != null) {
                NetworkInfo resultMobile = connect
                        .getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

                NetworkInfo resultWifi = connect
                        .getNetworkInfo(ConnectivityManager.TYPE_WIFI);

                if ((resultMobile != null && resultMobile
                        .isConnectedOrConnecting())
                        || (resultWifi != null && resultWifi
                                .isConnectedOrConnecting())) {
                    return true;
                } else {
                    return false;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        return false;
    }
