ubuntu server 22.04.3 配置 wifi

1. 配置 wifi

1.1. 查看系统中的网卡

ls /sys/class/net/

$ ls /sys/class/net/
enp1s0  lo  wlo1

1.2. 配置 wifi

1.2.1 一个普通的配置

加入我们的机器可能会链接多个网络中的某一个：

网络热点1：ChinaNet-zNpQ password: 123456

网络热点2：Starbuck-net: password: 654321

network:
    version: 2
    wifis:
        wlo1:
            access-points:
                ChinaNet-zNpQ:
                    password: 123456
                Starbuck-net:
                    password: 654321
            dhcp4: true
            optional: true

1.2.2 一个需要验证的配置

  wifis:
    wlan0:
      dhcp4: true
      optional: true
      access-points:
        homewifi:
          password: "123456"
        companywifi:
          password: "123456"
        workssid:
          auth:
            key-management: eap
            method: peap
            identity: "NEWYORK\Parker"
            password: "123456"
            ca-certificate: /etc/the_ca.pem

1.3. 应用配置

sudo netplan apply

1.4. 其他配置

为了避免长时间检索系统：

A start job is running for wait for network to be Configured

做如下配置：

将不是一直在线的网卡设为optional，即可选，不是必须长时间等待它被配置

sudo vim /etc/netplan/00-installer-config.yaml

# This is the network config written by 'subiquity'
network:
    ethernets:
        enp1s0:
          dhcp4: true
          optional: true
    version: 2

不是tab，而是4个 white space

1.5. 应用配置

sudo netplan apply

2. apt 国内源
