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

1.2.2 一个需要验证的配置

  wifis:wlan0:dhcp4: trueoptional: trueaccess-points:homewifi:password: "123456"companywifi:password: "123456"workssid:auth:key-management: eapmethod: peapidentity: "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: trueoptional: trueversion: 2

不是tab，而是4个 white space

1.5. 应用配置

sudo netplan apply

2. apt 国内源
