我不擅长网络故障排除。我尝试了很多步骤，但还是无法解决这个问题。
我可以将我的 PC 连接到两个不同的调制解调器无线路由器组件。当我连接到调制解调器无线路由器 #1 时，我可以正常连接互联网并完全访问 Skype 功能。
当我连接到调制解调器无线路由器 #2 时，我可以拥有与 #1 相同的连接级别，但我无法完全访问 Skype。我可以登录，可以打电话，但无法聊天、发送文件或传输，也无法查看他人的状态（甚至我自己的状态都无法查看）。
我在两个网络中都运行过ipconfig /all，得到的结果如下：

答案1
从我根据这些信息得知的情况来看，您的 PC 部分一切看上去都正常。
防火墙会干扰第二个连接吗？会阻止 Skype 使用的某些端口吗？
请打开与任何人的聊天并输入以下内容“/dumpmsnp”。
请分享输出。
