我遇到了这个问题，一开始似乎有点常见，但经过深入研究后，我确信这是一个非常罕见的情况，所以：
- 我的电脑（Asus VivoBook Max F541NA）似乎只能与 Windows 10 兼容，但是 Windows 崩溃了，所以我决定切换到 Ubuntu。
- 我安装了 Ubuntu 18.04.4 LTS，除了 Wi-Fi 适配器之外，一切运行正常。
- 我尝试了网络上几乎所有与我的问题类似的解决方案，但没有任何效果。
- 看起来 Ubuntu 甚至看不到 Wi-Fi 适配器（它没有显示
lspci）。 - 我尝试安装更新、安装驱动程序、拔下并重新插入里面的 Wi-Fi 设备，以及在 BIOS 中停用然后重新激活网络。
- 我的 Wi-Fi 适配器是：WCBN611LH-AD(1A)
