netplan 配置 wifi

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

    wifis:
        wlan0:
         dhcp4: false
         addresses: [192.168.1.101/24]
         gateway4: 192.168.1.1
         nameservers:

         access-points:
             "xxxxx":
                 password: "xxxxx"
