我最近收到了我的新电脑，一台联想 Thinkpad P14s 笔记本。根据数据表，它配备了 Realtek RTL8852AE（WiFi-6、802.11ax、2x2 双频）WiFi 适配器和一个标准 RJ45 以太网端口。
但是，安装 Ubuntu 20.04 LTS 后，根本没有 WiFi 可用。我在网上做了一些研究，发现有人建议安装 Ubuntu 21.04。但是，这也行不通。现在，我拿了一根 LAN 电缆，并尝试通过以太网连接，但发现这也行不通，尽管系统显示其中一个以太网适配器正在连接（但从未完成连接）。
一些输出：

除了回到 Windows 之外，我还能做什么来让该系统正常工作？我不是 Linux 专家，所以我正在寻找最简单的解决方案。

答案1
经过几天的网上研究和尝试各种可能的解决方案，我终于找到了解决方案。它很简单：
sudo apt install linux-oem-20.04d
正如在处理驱动程序的 Github 存储库中出现的问题所示（https://github.com/lwfinger/rtw89/issues/75)，Ubuntu 20.04 的 OEM 版本确实已经包含驱动程序。我试过了，效果很好。
注意：在此之前，我致电了联想 Premier Support，他们告诉我问题恰恰出在联想 Thinkpad P14s 的第 2 代变体上，因为这款笔记本不正式支持 Ubuntu，而对于第 1 代变体，Ubuntu 社区已经包含了认可的驱动程序。
