自从联想去年（2020 年夏天）宣布他们的许多型号正式支持 Ubuntu 以来，我就敢于购买联想 Thinkpad L15 Gen2 AMD，希望能避免这种情况......但不幸的是，wifi 适配器无法工作... :( 你有什么建议给我吗？谢谢！

我已经尝试过的：以下发行版的 live-iso：
- Kubuntu kubuntu-21.04-桌面-amd64
- Manjaro manjaro-kde-21.0.7-210614-linux510.iso
- 流行操作系统 pop-os_21.04_amd64_intel_6.iso
-> 它们都不支持 wifi 硬件
安装 Kubuntu 21.04 后，我可以打印以下信息：
