我刚刚打开笔记本电脑，但 Wi-Fi 不可用！我无法查看 Wi-Fi 设置，也无法打开/关闭它检查此截图和此截图。我已经安装了 Ubuntu 和 Windows 10。第一次使用 Ubuntu 时，我的 wifi 运行得很好。我正在使用Ubuntu 20.04.2 LTS我的内核版本是Linux 5.8.0-48-通用，已更新至最新版本。我确实搜索了很多次，但找不到任何解决方案。
我通过以下方式收集了一些有关我的 Wi-Fi 的信息脚本并将输出粘贴到这里：

如果有人能帮助我，我将非常感激。
答案1
刚刚注册以添加此内容，因此我无法点赞和/或评论，但 Windows 中的“关闭快速启动”可以解决问题，需要将其设置为最佳答案，因为“按住电源按钮关闭电源”对文件系统确实很不利
答案2
要正确解决此问题，您必须禁用 Windows 快速启动：
离开 Windows 时始终关闭，因为您在配置中看到“重启不受影响”。
正如iwlwifi 文档：
关于 Windows 双启动和启用“快速启动”
如果您有一台装有较新版 Windows 的双启动机器，并且在启动 Linux 时在 WiFi 设备初始化过程中开始看到问题，则问题可能是由于 Windows 上的“快速启动”功能造成的。
启用此功能后，Windows 不会真正关闭整个系统，而是让部分系统继续运行，以便您可以更快地再次启动机器。尝试禁用此选项，在 Windows 10 上，它应该位于“控制面板→硬件和声音→电源选项→系统设置”中。选择“选择电源按钮的功能”以从电源选项访问系统设置。然后禁用“关机设置”中的“快速启动”选项。这将导致 Windows 完全关闭并可能解决问题。
答案3
解决了我的问题只是通过按住电源按钮关闭我的笔记本电脑！因为我有Ubuntu旁边Windows 10，我认为它们都会相互影响，并在关机/重启之前更改一些设置；就像一些问题一样耳机或这个无线上网问题。
希望这能够帮助其他朋友。
答案4
关掉 Windows，“快速启动”才是关键！双启动时，Windows 10 保持网卡连接以加快启动速度，从而阻止使用 ubuntu。以下链接中有描述 -https://www.howtogeek.com/243901/the-pros-and-cons-of-windows-10s-fast-startup-mode/
