Ubuntu22.04 服务器版连接WiFi

• 首先通过ip a查看无线网卡的名字,我的是wlp3s0

$ 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: enp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether 00:e0:4c:04:b8:3b brd ff:ff:ff:ff:ff:ff
3: wlp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether 24:18:c6:37:4d:79 brd ff:ff:ff:ff:ff:ff

• 编辑配置文件/etc/netplan/00-installer-config-wifi.yaml注意文件名可能不一样,请根据实际情况选择,如果你不是root,那么需要sudo,文件内容为:

• wlp3s0为网卡名字,根据实际情况修改,yaml文件通过2个空格确定上下级关系,需要严格遵守.

• 配置dhcp自动获取

network:
  version: 2
  wifis:
    wlp3s0:
      dhcp4: true
      access-points:
        "WiFi名字,根据实际情况修改":
          password: "WiFi密码,根据实际情况修改"

• 配置静态ip

network:
  version: 2
  wifis:
    wlp5s0:
      dhcp4: false
      addresses: [192.168.1.3/24]
      gateway4: 192.168.1.1
      nameservers:
        addresses: [114.114.114.114,8.8.8.8]
      optional: true
      access-points:
        你的wifi名称:
          password: 你的wifi密码

• 重启网络
