注意：这不仅适用于 Ubuntu。我还没有能够让这台机器上的 wifi 工作。我试过 Debian、Arch、Ubuntu、Mint、POP、Arco 等。WiFi 不起作用。我一直收到无法找到 wifi 适配器的消息。
注意：我发现此链接表明这台笔记本电脑已通过 Ubuntu 认证。

我目前正在使用 23.04 Ubuntu。

==== 我安装了 Windows，我的 wifi 可以工作，并且驱动程序/固件也是最新的。
我找到了这个：Dell Latitude 5521 WiFi 无法在 U20 LTS 上使用我认为那里提到的 sudo 命令不起作用是因为该文件不再以该名称命名？

这不是一个双启动系统。
