这是我的第一篇文章。
是的，我检查了 Askubuntu 上所有其他有类似问题的帖子，但似乎没有任何适用于 2021 的解决方法。答案已经过时，链接也不起作用。我希望主板上的网卡能够找到 wifi。所以我可能需要一些适合我内核类型的驱动程序。我尝试安装以前的内核，但似乎没有任何效果。
我的内核是 5.8.0-55-generic。lshw -C network 的输出是

我还发现了这个 [https://linux-hardware.org/?id=pci:1969-e091-1462-7918][1]，它是一个内核驱动程序，但我尝试用 gcc 编译该文件，一直出现头文件错误，因为 gcc 在错误的文件夹中查找它们。
任何能为你的 Linux 兄弟（我）提供的帮助都将不胜感激！
PS. 如果您需要任何其他输出，我将编辑该问题并将其粘贴在那里。

这看起来像是一个 LAN 控制器，不支持 W-LAN。请链接或命名您的确切控制器（或主板），因为我找不到有关它的任何信息。
