AdMob Banner不適用於移動數據

我最近開始在Android應用程序開發中，並且在嘗試在我的應用程序中加載橫幅時，我在logcat中出現以下錯誤。AdMob Banner不適用於移動數據

03-02 17:30:58.509: I/Ads(12181): Use AdRequest.Builder.addTestDevice("My device ID") to get test ads on this device. 
03-02 17:30:58.509: I/Ads(12181): Starting ad request. 
03-02 17:30:58.799: W/Ads(5515): Error while connecting to ad server: failed to connect to googleads.g.doubleclick.net/74.125.225.250 (port 80) after 60000ms: isConnected failed: ENETUNREACH (Network is unreachable) 
03-02 17:30:58.799: W/Ads(12181): There was a problem getting an ad response. ErrorCode: 2 
03-02 17:30:58.939: I/Ads(12181): Scheduling ad refresh 60000 milliseconds from now. 
03-02 17:30:58.939: W/Ads(12181): Failed to load ad: 2

它只是發生在某些設備（主要是在搭載Android 4.1果凍豆），並只對移動數據（使用墨西哥的Telcel），它適用於無線網絡的預期。

我的xml和java代碼與AdMob實施指南相同。

layout.xml旗幟

<com.google.android.gms.ads.AdView 
     android:id="@+id/adView" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentBottom="true" 
     android:layout_centerHorizontal="true" 
     ads:adSize="BANNER" 
     ads:adUnitId="My Add Unit Id (Hidden)" />

MainActivity onCreate方法

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     AdView adView = (AdView) this.findViewById(R.id.adView); 
     AdRequest adRequest = new AdRequest.Builder().build(); 
     adView.loadAd(adRequest); 
    }

希望你能幫助我解決這個問題。
