Please try this

public static boolean isInternetConnected (Context ctx) {
    ConnectivityManager connectivityMgr = (ConnectivityManager) ctx
            .getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo wifi = connectivityMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
    NetworkInfo mobile = connectivityMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
    // Check if wifi or mobile network is available or not. If any of them is
    // available or connected then it will return true, otherwise false;
    if (wifi != null) {
        if (wifi.isConnected()) {
            return true;
        }
    }
    if (mobile != null) {
        if (mobile.isConnected()) {
            return true;
        }
    }
    return false;
}
