我已经从 Vista 升级到 Windows 7。在 Vista 上，我曾经运行一张网卡（Intel 82566DC -2 Gigabit）用于互联网，该网卡连接到与 3G 调制解调器连接的 Dovado USB 移动宽带路由器。卡上的 IP 设置设置在 DHCP 上。第二张卡（3com 以太网链路）用于连接到我们镇的本地 WUG（无线用户组），一切运行正常。
现在我在使用 Windows 7 时遇到的问题是，当我使用 (Intel) 第一块卡连接到互联网时，互联网工作正常，但当我将第二块卡连接到 wug 时，互联网就断线了。如果我断开第一块卡（互联网卡）的连接并尝试连接到 wug，它就可以正常工作。
看起来这两张卡在互相争斗。我能做些什么来解决这个问题吗？从这篇文章中你可能已经知道，我不是 PC 专家，所以如果你要回答的话，请用简单的术语来回答。:)
答案1
删除第二个接口上的专用网络网关。我有一段时间遇到同样的问题，所以我的无线网络接口与互联网的网关为 192.168.1.0/24，网关为 192.168.1.1，我的专用网关为 10.0.0.0/8，没有网关。
如果您在不同的网络上设置了 2 个网关，并且 NIC 的窗口将通过带宽最高的 NIC 发送所有出站流量，而不管指标如何（至少在我的情况下）
由于无线仅为 G 型（54Mpbs），而有线为 GigE（1000Mbps），因此它通过有线连接发送所有流量。
一旦我取出私有网络网关（仅保留静态 IP 和子网），我仍然可以浏览互联网并访问我的私人文件服务器。
但是，如果您将私有网络 NIC 运行到路由器中，则插入路由器的任何设备都将无法访问互联网。
我设置网络的方式是将第一个有线网卡插入路由器的 WAN 端口，然后在 Windows 中将该网卡和无线网卡桥接。然后，我将第二个有线网卡插入路由器的一个端口，并仅配置 IP 和子网。
这使得我的文件服务器仍然可以访问互联网，并允许我访问它，同时仍然保持整个有线网络的私密性，并且只允许我自己访问它，并阻止通过我的共享 wifi 连接的其他用户访问我的文件服务器。
答案2
我在 Windows 7 Pro 64 位笔记本电脑中使用以下脚本，同时使用有线和无线网卡以及单个默认网关，希望这会对您有所帮助。您可能需要对该脚本进行一些更改，因为我不知道您的 IP 和接口名称，而且我多次使用删除命令，因为我的接口 IP 需要删除（我不知道为什么）仍然不明白为什么我的接口需要手动删除 ips。
