在运行 Ubuntu 22.04 的华硕上“未找到 Wifi 适配器”，如何诊断问题？

Question

Machine       : ASUS X550VX
System        : Ubuntu 22.04
Kernel        : 5.15.0-40-generic
Wireless Card : Realtek RTL8723BE

突然我的 wifi 消失了，并且无法打开它，它显示“未找到 wifi 适配器”。之前一切都很好，我没有搞乱任何网络设置，现在已经两天了，我的 wifi 无法工作。apt update和的更新没有运气apt dist-upgrade。

有关我的系统的信息：

ifconfig -a （wifi甚至没有列出）

我尝试过的（多次重新启动）：

1. rfkill unblock all
2. sudo apt reinstall network-manager && sudo service network-manager restart
3. sudo snap install network-manager（通过安装网络管理器snap）
4. 按照此线程安装iwlwifi：在 MSI GE66 笔记本电脑上安装新的 Ubuntu 20.04 时找不到 WiFi 适配器，以及其他奇怪的行为
5. 安装 RTL8723BE 驱动程序git clone https://github.com/lwfinger/rtw88.git

我不知道从这里还能去什么或尝试什么，有什么建议吗？

[更新 02/06/2022]

根据评论的建议，我删除了“我的无线/WiFi 连接不起作用”之后iwlwifi包含的无线信息（要点） 。诊断问题需要哪些信息？

Answer 1

为了解决这个问题，我将内核从5.17更改为5.13。然后我安装了网络驱动程序iw、、iwd并linssid重新urfkill启动。
