![以太网无人认领](https://linux22.com/image/923459/%E4%BB%A5%E5%A4%AA%E7%BD%91%E6%97%A0%E4%BA%BA%E8%AE%A4%E9%A2%86.png)
Ubuntu 20.04 LTS 最近升级
有线以太网突然变成“未认领”。我可以在哪里查找此问题?
下面发布了一些我用于调查的命令,我希望能从 Linux 专家那里获得更多帮助。
我首先不确定编译了什么驱动程序(大概是 r8169,如下面 lsmod 所报告的),然后内核应该为 Realtek 810xE 使用什么驱动程序?
我不记得卸载过任何以太网驱动程序/模块,那么为什么我必须寻找驱动程序,因为在过去的4-5年里我从来没有遇到过这个盒子上的以太网问题?
太感谢了。
更新:以太网问题不知怎么解决了。我不得不部署 r8101 而不是 r8169。我不知道为什么以及如何安装 r8169,也不知道 r8101 是否是正确的选择,但运行良好
ifconfig 没有列出以太网

TLDR:更新你的 Linux 内核
将 Ubuntu 18.04 升级到 Ubuntu 20.04 后,我遇到了同样的问题。对我来说,不仅以太网,而且 WiFi 也是Unclaimed
状态(输出sudo lshw -C network
)。不仅如此,我的触控板也坏了。
Linux 内核是5.8.0-X-generic
。
在使用其他版本的内核(我选择了最低版本的内核)启动到 Ubuntu 恢复模式后,我可以看到网络设备,但这次处于DISABLED
状态。
奇怪的是,运行后nmcli dev show
,DISABLED
状态消失了。我可以访问互联网。
我将 Linux 内核更新到最新版本。我遵循本教程的方法 #2。
内核更新后,您可以以正常模式重新启动。希望它能正常工作。
附言
您可以寻求帮助https://linux-hardware.org/检查您的以太网和无线适配器是否受特定的操作系统版本和内核版本支持。
