未找到 Wi-fi 适配器（仅限登录 Windows 后第一次启动）

当我在登录 Windows 后第一次登录 Linux 时，Wi-Fi 设置中总是显示：未找到 wifi 适配器。然后，我重新启动 PC，Wi-Fi 总是可以正常工作。由于它变得非常重复并且是一种非常无聊的方法，我想知道这个问题的原因以及可能的解决方案。

我的电脑是华硕笔记本电脑 x571gt，我使用的 Ubuntu 版本是 18.04.4 LTS。

问题在于 Windows 快速启动功能。

当您关闭 Windows 时，它并不是真正关闭，而是处于休眠状态。

这可能会给包括无线硬件和 NTFS Windows 分区访问在内的双启动系统带来麻烦。

建议在 Windows 设置中禁用此功能。
