Ubuntu 20.04.1 LTS 无法访问 Wifi

Question

我最近在笔记本电脑上安装了 Ubuntu 20.04.1 LTS，每次打开笔记本电脑时，Wifi 选项都被禁用。
为了启用它，我不得不运行以下命令并重新启动笔记本电脑（每次都是这样）。

sudo service network-manager restart

有什么办法，可以让 Ubuntu 自动检测 Wifi，而无需重新启动network-manager？

我已禁用安全启动，
安装 Ubuntu 时无法连接到 Wifi。
我正在双启动 Ubuntu 和 Windows 10

如果你们知道这个问题的永久解决办法，请告诉我，

编辑您的 /etc/netplan/*.yaml... 保持完全相同的缩进、间距和无制表符...

sudo -H gedit /etc/netplan/*.yaml# 使用正确的 .yaml 文件名

# Let NetworkManager manage all devices on this system
#
network:
  version: 2
  renderer: NetworkManager

sudo netplan generate

sudo netplan apply

reboot

然后转到顶部面板右侧的 NetworkManager 小程序并选择您的 wifi 网络。
