我有 Windows 10 和 Ubuntu 20.04 的双启动设置。我能够在 Windows 10 中连接到 WiFi，但 Ubuntu 设置显示“未找到 WiFi 适配器”。但总是发生一件奇怪的事情。当我先启动 Windows 10，然后重新启动并启动 Ubuntu 时，我可以连接到 WiFi。但是当我启动 Windows 10，然后关闭并启动 Ubuntu 时，再次找不到 WiFi 适配器。简而言之，从 Windows 10 重新启动，然后进入 Ubuntu（WiFi 工作正常），但关闭 Windows 10 并启动 Ubuntu（WiFi 无法工作）。每当我必须在 Ubuntu 上使用互联网时，我都必须先启动 Windows 10 并重新启动（不关闭）并重新启动 Ubuntu 才能使用互联网。请帮助我。提前致谢。
