树莓派版本: Raspberry Pi 4B

操作系统 : Ubuntu Server 20.04_x64

使用 ip a 查看无线网卡名称:

ubuntu@ubuntu:~$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether dc:a6:32:6b:bd:cf brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.147/24 brd 192.168.1.255 scope global dynamic eth0
       valid_lft 603225sec preferred_lft 603225sec
    inet6 fe80::dea6:32ff:fe6b:bdcf/64 scope link
       valid_lft forever preferred_lft forever
3: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
    link/ether dc:a6:32:6b:bd:d0 brd ff:ff:ff:ff:ff:ff
ubuntu@ubuntu:~$

eth0是有线网卡,wlan0是无线网卡,接下来改/etc/netplan/下的YAML配置文件,不同的机器文件名不一样 :

ubuntu@ubuntu:~$ ls /etc/netplan/
50-cloud-init.yaml
ubuntu@ubuntu:~$ cat /etc/netplan/50-cloud-init.yaml
# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-inits
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        eth0:
            dhcp4: true
            optional: true
    version: 2
ubuntu@ubuntu:~$

修改后的内容:

ubuntu@ubuntu:~$ cat /etc/netplan/50-cloud-init.yaml
# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-inits
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        eth0:
            dhcp4: true
            optional: true
    version: 2

    wifis:
        wlan0:
            dhcp4: true
            access-points:
                "wifi的ssid":
                    password: "wifi密码"

ubuntu@ubuntu:~$

配置生效:

ubuntu@ubuntu:~$ sudo netplan try
ubuntu@ubuntu:~$ sudo netplan apply
