前言
首先确实是否安装了网卡驱动。

lo
开头的表示本地连接。如果没有en
开头的,表示有线网卡驱动存在问题。因此,需要进一步确定网卡的驱动型号。

百度一下,可知为e1000e驱动,上Intel的官网下载(https://downloadcenter.intel.com/download/15817/Intel-Network-Adapter-Driver-for-PCIe-Intel-Gigabit-Ethernet-Network-Connections-under-Linux-)
即可。我下载的目前最新的版本3.8.4。

| # 1.解压
$ tar zxf e1000e-3.8.4.tar.gz
# 2.进入安装目录
$ cd e1000e-3.8.4/src
# 3.安装
$ sudo make install
|
一般会安装在/lib/modules/`uname -r`/updates/drivers/net/ethernet/intel/e1000e/e1000e.ko下,
不过要让驱动能正常使用,需要将e1000e.ko
复制到 /lib/modules/`uname -r`/kernel/drivers/net/ethernet/e1000e.ko中

| # 4.重载
$ sudo depmod -a
# 5.Rebuild initramfs
$ sudo update-initramfs -u -k all
# 6.Check the driver version
$ modinfo e1000e | grep version
# 7.Load the driver module
$ modprobe e1000e

之后,可能需要重启,然后再次确认ifconfig

如果出现了en
开头的字符,比如上面的eno1
或其他字符,则表明网卡驱动安装成功。这时候,
如果打开Ubuntu的网络设置界面,可能仍然看不到关于有限网连接的菜单。但是,我们可以通过
在命令行手动设置一些网络参数来上网。

| # 8.将eno1设置为活动模式
$ sudo ip link set dev eno1 up
# 9.进入网络设置目录
$ cd /etc/netplan
# 10.修改其中的网络配置文件的参数
$ ls
01-netcfg.yaml
# 下面是我修改的结果
$ cat 01-netcfg.yaml
# This file describes the networks interfaces available on your system
# For more information, see netplan(5).

version: 2
renderer: networkd

参数文件中的eno1
需要和自己ifconfig
所对应的en
开头的名称一致。
