使用 Ubuntu 12.10 时，我的网络仍然无法连接互联网。我的路由器是 NetGear 192.168.1.1，TP-Link 运行在 192.168.1.2 上，Ubuntu 通过有线连接到 TP-Link 192.168.0.200。它运行正常，但有时 IP 未更新，导致我断网。我通过插拔有线连接，直到我拥有 192.168.1.3 或 192.168.0.200 IP，然后kill-9重新启动dhcpcd eth0。我搞不清楚这个 192.168.1.3 地址从何而来，我认为这就是问题的根源。我在我的 dhcp 别名文件中看到了以下内容：
lease {
interface "eth0";
fixed-address 192.168.1.3;
option subnet-mask 255.255.255.0;
option dhcp-lease-time 86400;

}

}
对我来说更奇怪的是：ifconfig 说我正在运行我想要的 192.160.0.200，但 GUI（活动连接）说我有 192.168.1.3：

如果有什么需要的话，请告诉我还需要什么。也许这与它尝试使用 IPv6 有关？我从 syslog 中得到了这个想法：

新的附加信息：TP-Link 已插入 NetGear 的 LAN 端口（因为 Internet 位于 NetGear 的 WAN 中），这是 TP-Link 的 WAN - 所以正确。现在另一个问题：我重新启动了连接，丢失了它，当我插上电线并再次打开时，TP-Link 在 DHCP 客户端列表下列出了我的 Ubuntu，其正确的 IP 为 192.168.0.200，在 ARP 列表中，我的 Ubuntu Mac 映射到这个 IP，所以看起来 TP-Link 可以正确看到并识别我的主机，但主机本身说没有连接，再次：杀死 dhcpcd eth0 并重新启动它给我的信息是主机 IP 配置正确。但是这次我杀死了而不是 -9，我得到的信息是：
接口 eth0 已配置新 IP=192.168.0.202
而不是 192.168.0.200 来自 syslog 的日志信息：

答案1
kill -9首先，除非常规方法不起作用，否则不要使用kill。其次，您的描述很难理解，但听起来您有两个路由器，一个插入另一个。你不应该这样做。我猜你让第二个路由器通过常规端口连接到第一个路由器，而不是第二个路由器的 WAN/UPLINK 端口。如果这样做，您必须禁用第二个路由器中的路由/NAT/DHCP 功能。否则，您需要使用 WAN/UPLINK 端口将其连接到上游路由器。
