所以我买了一台新电脑（L13 yoga 带 Intel AC9560），我想安装 Linux。更具体地说是 Ubuntu，由于某种原因，wifi 适配器无法工作。在设置中，它显示未找到，在系统日志中有一些有趣的错误。

所以我尝试了 18.04 和 19.10，但它们都不起作用。所以这里显示的输出来自 19.10。

所以我更新了 Linux 固件包，但没用。现在有趣的是，如果我从 USB 驱动器启动 18.04 和 19.10 的实时版本，它就可以正常工作。
英特尔表示，这款芯片从 4.14 版开始就得到 kenerel 的支持，而我得到的是 5.3 版。https://www.intel.co.uk/content/www/uk/en/support/articles/000005511/network-and-io/wireless-networking.html
我如何才能了解更多相关信息？我可以尝试什么？
答案1
我最终安装了 Fedora 31，内核为 5.5
