WCF无法通过无线连接到笔记本电脑

我试图在Windows 7x64和Studio 2012 Professional上使用WCF建立点对点连接。当笔记本电脑使用无线时，WPF停止工作。

我的电脑通过以太网电缆连接到网络交换机，我的笔记本电脑通过有线连接到同一个网络，WCF工作。

,

当我的电脑通过以太网电缆连接到网络交换机，而我的笔记本电脑使用无线连接到同一网络时，WCF不工作。

我确实更新了有线和无线之间的端口号。

任何帮助的回答都是非常感谢的。

错误如下:

Error()
{
    System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://100.100.1.90:9000/test_robot_client. The connection attempt lasted for a time span of 00:00:01.0430000.

当尝试发送WCF命令时，我使用Catch(Exception ex)看到上述错误。

谢谢!
