  开发板：Luckfox-Pico-Ultra-W
  系统：网盘 Luckfox_Pico_Ultra_W_eMMC
  操作步骤：参考文档 https://wiki.luckfox.com/zh/Luckfox-Pic ... tra-W-WIFI

  Code: Select all

  [root@luckfox root]# cat /etc/wpa_supplicant.conf
  ctrl_interface=/var/run/wpa_supplicant
  ap_scan=1
  update_config=1
  
  network={
          ssid="8266_Only"
          psk="<rm>"
          key_mgmt=WPA-PSK
  }
  [root@luckfox root]# ip addr
  1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue 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
  2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq qlen 1000
      link/ether 5a:cd:99:04:06:4d brd ff:ff:ff:ff:ff:ff
      inet 192.168.25.48/24 brd 192.168.25.255 scope global eth0
         valid_lft forever preferred_lft forever
  3: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq qlen 1000
      link/ether 1c:2f:a2:27:3f:36 brd ff:ff:ff:ff:ff:ff
  4: usb0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000
      link/ether da:dd:90:74:48:e5 brd ff:ff:ff:ff:ff:ff
      inet 172.32.0.93/16 brd 172.32.255.255 scope global usb0
         valid_lft forever preferred_lft forever
         

  问题：wlan0 接口无 IP 地址，路由器上显示为 0.0.0.0

  

  请问应该如何解决？
