联想 Thinkpad X1 Carbon 第三代 - 未找到 W-Fi 适配器

我已经使用联想 Thinkpad X1 Carbon 3rd Gen 近一年了，一直没有问题，直到现在。今天下午启动时，它无法通过 Wi-Fi 连接到网络。

通过 askubuntu 查看，我搜索了以前的解决方案，但没有成功。请帮忙。

以下是我在其他线程中看到的一些命令的输出。如果需要更多信息来解决这个问题，请告诉我！

编辑：附加信息。

奇怪的是，重新启动计算机可以暂时解决问题，但是当计算机进入睡眠模式并从睡眠模式返回时，它再也无法找到 Wi-Fi 适配器。

以下是 Marmayogi 建议的命令的输出：
