我已经尝试过（多次重启）：
rfkill unblock allsudo apt reinstall network-manager && sudo service network-manager restartsudo snap install network-manager（通过 安装网络管理器snap）iwlwifi按照此线程进行安装：MSI GE66 笔记本电脑上安装全新 Ubuntu 20.04 后未找到 WiFi 适配器，且出现其他奇怪行为- 安装 RTL8723BE 的驱动程序
git clone https://github.com/lwfinger/rtw88.git
但毫无进展之后我发现了一些有趣的信息：

我不知道接下来还能去哪里或者尝试什么，有什么建议吗？
[更新日期 2022/06/02]
根据评论的建议，我删除了iwlwifidan 包括我的无线信息（要点）下列的我的无线/WiFi 连接无法使用。诊断问题需要哪些信息？
答案1
为了解决这个问题，我将内核从 5.17 改为 5.13。然后我安装了网络驱动程序iw，，，并重新启动iwd。linssidurfkill
