更新 1：评论中建议的命令输出

我有一台全新的联想 X1 Extreme Gen4，预装了 Ubuntu（我认为是 20.04）。Wifi 无法使用，不知道该怎么办。所以我决定无论如何都要升级到 Ubuntu 22.04。但 WiFi 仍然无法使用。所以我在网上查了一下（见下面的帖子）。硬件似乎被正确识别，但接口永久断开。

我在网上查找了类似的帖子：

甚至可以尝试一些通用的修复方法，例如“Linux 中的 Wi-Fi 无法使用？以下是解决方法”。

以下是我的规格和一些有用的输出。运行后sudo lshw -C network我得到：

运行sudo modprobe iwlwifi && sudo dmesg | grep iwl我得到：

sudo modprobe iwlwifi命令没有显示任何内容... :/

因此，我决定连接我的智能手机并通过 USB 网络共享来访问互联网，正如您在运行时所看到的nmcli，我得到：

Use "nmcli device show" to get complete information about known devices and
"nmcli connection show" to get an overview on active connection profiles.

Consult nmcli(1) and nmcli-examples(7) manual pages for complete usage details.

输出rfkill：

ID TYPE      DEVICE                   SOFT      HARD

 2 wlan      phy0                unblocked unblocked

所以不确定如何激活界面并连接到互联网...有更多经验的人可以指出我在哪里可以找到问题吗？

多谢！

更新 2：站在路由器旁边跑步sudo iwlist wlp9s0 scan

我可以看到 2 和 5GHz 的两个网络，但大多数信息是未知的：

我在远离路由器的另一台计算机上运行了相同的命令，得到了更多结果（即邻居的网络），但有趣的是，Quality我的网络的值要高得多，例如 5.18GHz 为 44/70，2.4GHz 为 54/70。也许我的笔记本电脑的天线工作不正常？
