1. 首先安装程序

sudo apt-get install wpasupplicant
sudo apt-get install network-manager

2. 查看无线网卡名

ifconfig -a
或
ip a

找到无线网卡： wlan0

3. 配置无线网卡节点

sudo vi /etc/netplan/50-cloud-init.yaml

network:
        renderer: NetworkManager
        ethernets:
                eth0:

                        optional: true
        wifis:
                wlan0:
                        dhcp4: true
                        access-points:
                                "HUAWEI-00452L":
                                        password: "Abcd1234"

        version: 2

network:
    renderer: NetworkManager
    ethernets:
        eth0:
            dhcp4: true
            optional: true
    wifis:
        wlan0:
         dhcp4: false
         addresses: [192.168.1.101/24]
         gateway4: 192.168.1.1
         nameservers:
           addresses: [192.168.1.1]
         optional: true
         access-points:
             "xxxxx":
                 password: "xxxxx"

解释说明 `/24` 含义

4. 重启网络

sudo netplan generate
sudo netplan apply
