答案1
我的答案是错误的。看来我使用的参考是误报，事实上内核中还没有对 MT7902 的支持。
问题是您的笔记本电脑的 WiFi 芯片组是 MEDIATEK Corp. Wi-Fi 6EMT7902无线网络适配器。此适配器的驱动程序已添加到 Linux6.6内核系列中（根据https://linux-hardware.org/?probe=96859b01b76.5)，而22.04上只提供Linux内核系列。
您可以选择安装由 ubuntu 构建的最新内核，如https://wiki.ubuntu.com/Kernel/MainlineBuilds。
但是，如果您启用了安全启动，则可能会出现问题，因为主线版本的内核包通常未签名（这意味着安全启动过程不会将它们识别为有效的启动二进制文件）。要制作 6.6 系列或更高版本的主线内核，您需要按照其他步骤在笔记本电脑上对内核进行签名，如中所述https://ubuntu.com/blog/how-to-sign-things-for-secure-boot。
