مشكلة في تشغيل WiFiWebClient سبيل المثال

أنا أشغل مثال WiFiWebClient الذي يأتي محملاً مسبقًا بـ Arduino IDE 1.6.7. أستخدم لوح Arduino Uno مع WiFi Shield Model R3.

/*
  Web client

 This sketch connects to a website (http://www.google.com)
 using a WiFi shield.

 This example is written for a network using WPA encryption. For
 WEP or WPA, change the Wifi.begin() call accordingly.

يحصل على درع WiFi متصل بـ Vanilla Sky ولكنه لا يجلب طلب HTTP (انظر الصورة أدناه). ما هو الخطأ هنا؟
