问题

现在我没有通过集成卡进行有线网络连接。

  • 网络图标显示" No network devices available".
  • sudo lshw -C返回空
  • lspci -nn没有显示网络设备
  • 网卡上以正常方式闪烁
  • 在BIOS中启用板载LAN

我尝试了一个在其他地方看到的方法:

  • service network-manager stop
  • rm /var/lib/NetworkManager/NetworkManager.state
  • service network-manager start

还是没搞定。

答案1

进入你的BIOS,确保板载网卡处于打开状态,即使它正常,试着再次打开它,然后重置为默认值,并重新启动。

关闭BIOS的启动画面,注意网卡固件是否加载,是否看到PXE字样?这将告诉你网卡是否正常工作。


答案2

使用旧内核和备用操作系统尝试网卡。

这两个选项都不能工作,那么它更可能是一个硬件问题。


答案3

使用旧的Live CD启动,并检查dmesglspci,查找它是否被检测到,并加载了驱动程序,如果没有,你可能有硬件问题。
