Ubuntu22.04配置WiFi

注意：在/etc/netplan/​下的配置文件，格式一定要正确，否则用sudo netplan try​的时候会报错

一、查看无线网卡的名称

//choice-1
ls /sys/class/net

//choice-2
ip a

//choice-3
ifconfig -a

‍

二、修改配置文件

文件路径：/etc/netplan/*.yaml​

修改前备份：sudo cp *.yaml *.yaml.bak​

修改：sudo vim *.yaml​

配置格式：

network:
        version: 2
        ethernets:
                eth0:
                        dhcp4: true
                        optional: true
        wifis:
                wlan0:
                        dhcp4: true
                        optional: true
                        access-points:
                                "ZhaoLan":
                                        password: "zlkj2003"

示例：

network:
    ethernets:
        eth0:
            dhcp4: true
            optional: true
    version: 2
    wifis:
        wlp3s0:
            optional: true
            access-points:
                "SSID-NAME-HERE":
                    password: "PASSWORD-HERE"
            dhcp4: true

三、应用配置

​sudo netplan apply​
