C# WCF无法使用无线网络连接到笔记本电脑

我正在尝试在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网络连接到同一网络，WCF可以工作

但是,

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

我更新了有线和无线之间的端口号

非常感谢您的帮助

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.

在尝试发送WCF命令时，我使用CatchException ex看到上述错误

谢谢

我已经修好了。我在某个地方读到，有人提到要打开808端口。所以我就这么做了，而且成功了！谢谢大家的帮助

WCF服务是否托管在IIS中？它表示目标计算机主动拒绝它，以便我检查服务器上的防火墙。甚至尝试禁用服务器和客户端上的防火墙，以确保没有人拒绝网络通信。WCF服务不是IIS中的主机。这只是tcp。我试图关闭服务器和客户端的防火墙。我甚至关掉了Avast。问题依然存在。知道下一步是什么吗？很奇怪……如果我在笔记本电脑上运行服务器，在我的电脑上运行客户端，那么我可以在笔记本电脑处于无线状态时建立WCP连接。我得到了一个修复程序。我在某个地方读到，有人提到要打开808端口。所以我就这么做了，而且成功了！谢谢大家的帮助！！
