1. 参照 ubuntu18.04.3，配置netplan相关yaml

network:
  ethernets:
    enp2s0:
      dhcp4: true
  wifis:
    wlo1:
      dhcp4: true
      access-points:
        "<ssid>":
          password: "<passowrd>"
  version: 2

2. 先连接有线网络，安装无线网络配置工具

sudo apt install net-tools wireless-tools network-manager

3. 连接WiFi

nmcli dev wifi connect <ssid> password <password>

4. 开启常用端口，避免被防火墙拦截

sudo ufw allow ssh
sudo ufw allow http
sudo ufw allow https
