ubuntu 22.04 wifi网卡配置地址上网

通过network-manager配置

1. 确定是否存在usb网卡的驱动

    root@gpu-server:/etc/netplan# lsmod | grep  rt2800usb
    rt2800usb              32768  0
    rt2x00usb              24576  1 rt2800usb
    rt2800lib             139264  1 rt2800usb
    rt2x00lib              73728  3 rt2800usb,rt2x00usb,rt2800lib
   

2. 确定wfii接口名称
   

3. 下载network-manager

    root@test:~# apt-get  install network-manager wpasupplicant -y
   

• wpa_supplicant: 是一个 Linux/Unix 系统下的开源软件，用于支持 Wi-Fi 连接的认证和加密（如 WPA/WPA2/WPA3）。它负责与无线网卡驱动交互，完成密码验证、密钥协商等安全流程，使设备能连接到受保护的 Wi-Fi 网络。

4. 查询当前设备环境的wifi列表

   root@test:~# nmcli dev wifi list
   IN-USE  BSSID              SSID          MODE   CHAN  RATE        SIGNAL  BARS  SECURITY

5. 使用命令行连接wfii （二选一）

   root@test:~# nmcli dev wifi connect "iQOO9" password "12345678"
   

   

6. 使用netplan配置文件连接（二选一）

    root@test:~# cat /etc/netplan/50-cloud-init.yaml
   

   network:
       version: 2
       renderer: NetworkManager
       ethernets:
           ens33:
             addresses: [192.168.25.158/24]
       wifis:
         wlxfc221c300047:
           dhcp4: yes
           optional: true   
           access-points:
             iQOO9:
              password: "12345678"
   

• wlxfc221c300047：wifi接口名称

• iQOO9：wifi名称

• password：wifi密码
