优麒麟 昨晚看到有更新提示 结果更新后重启无网络


20.04.1 LTS
昨晚更新  完成后提示重启


重启后发现没有网络


命令   ifconfig   只显示   l0 的信息  


没有网卡的信息  


找到添加网络连接的地方    发现下拉列表没有网卡MAC


可能 网卡 硬件  没有识别


这个要怎么搞？？？  不会要我重装系统吧 ？？

请问能提供下是啥网卡，啥驱动吗？dmesg输出到一个文件发出来看看？lspci信息也麻烦看看。

是不是把硬件设备这些给禁掉了，开机的时候进下bios设置看看？

ifconfig -a 有输出吗，有的话执行sudo ifconfig (网卡名) up 试试
