我买了一台新笔记本电脑（Lenovo thinkbook 15 gen 4），安装了 Ubuntu 22.04.1 LTS。内核似乎不包含 WiFi 适配器的驱动程序。
我如何才能知道我需要什么驱动程序？我已经尝试过这里写的方法https://help.ubuntu.com/stable/ubuntu-help/net-wireless-troubleshooting-hardware-check.html.en
“lshw -C network” 的输出

我认为上述情况意味着 WiFi 适配器未被识别？我该怎么做才能安装驱动程序并让 Ubuntu 识别 WiFi 适配器？我确信有一个，因为计算机之前运行的是 Windows，WiFi 工作没有任何问题。
答案1
我通过查找网络适配器型号解决了这个问题。然后我下载并安装了驱动程序。现在 WIFI 可以正常工作了
