Raspberry Pi without screen, configure WiFi in SD card

WiFi network configuration

The operation method is simple:

• Use the computer to read the SD card flashed with the Raspbian system. Create a new wpa_supplicant.conf file in the boot partition, that is, /bootthe directory , fill in the content according to the following reference format and save the wpa_supplicant.conf file.

• country=CN
  ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
  update_config=1
  
  network={
        
        
  ssid="WiFi名"
  psk="密码"
  key_mgmt=WPA-PSK
  priority=1
  }
  
  network={
        
        
  ssid="WiFi名"
  psk="密码"
  key_mgmt=WPA-PSK
  priority=2
  scan_ssid=1
  }
  

  • Instructions and example WiFi configurations with different security:

    • #ssid: the ssid of the network
    • #psk:password
    • #priority: connection priority, the higher the number, the higher the priority (cannot be negative)
    • #scan_ssid: When connecting to hidden WiFi, you need to specify this value as 1

  • If your WiFi does not have a password

    • network={
                
                
      ssid="你的无线网络名称（ssid）"
      key_mgmt=NONE
      }
      

  • If your WiFi uses WEP encryption

    • network={
                
                
      ssid="你的无线网络名称（ssid）"
      key_mgmt=NONE
      wep_key0="你的wifi密码"
      }
      

  • If your WiFi uses WPA/WPA2 encryption

    • network={
                
                
      ssid="你的无线网络名称（ssid）"
      key_mgmt=WPA-PSK
      psk="你的wifi密码"
      }
