升级到 13.04 后，我无法使用有线连接（无线互联网工作正常）。我在连接设置中检查过它应该自动连接。
ifconfig 给出：

对我来说唯一可行的解决方案（我在以前版本的类似问题中发现）是在 /etc/network/interfaces 中添加以下几行。
auto eth0
iface eth0 inet dhcp
但是，每当我不使用有线连接启动时，我都会遇到网络配置问题，并且必须等待很长时间才能系统启动。
我知道问题出在我的 e1000e 驱动程序上（对吗？），但我不太清楚我能做些什么。我很感激任何建议。
答案1
尝试这个
echo on | sudo tee /sys/class/net/eth0/device/power/control
这肯定能解决整个问题……完成后，退出 sudo 并拔出，然后再次插入以太网电缆
