答案1

*-network未声明意味着没有安装驱动程序,查看以下wiki并执行这些步骤。

https://help.ubuntu.com/community/UbuntuBackports

完成后,重新启动并检查。


答案2

修改/etc/network/interfaces


nano /etc/network/interfaces



将这两行放在末尾:


auto eth0


iface eth0 inet dhcp



保存并重新启动。


答案3

默认情况下,所需的驱动程序r8169已安装在所有最新的Ubuntu版本中。尝试加载它:


sudo modprobe r8169



日志里有什么线索?


dmesg | grep r8169
