  • The user sets up a Wi-Fi environment with the SSID name wp_master and the password wp!987@dmin.
  • Set DHCP server option 43 and option 66 in the LAN.

Option 43 performs device CPE configuration, upgrade server path, network VLAN tag, and priority configuration.

Option 66 performs config server path configuration of the device upgrade module.

  • The device automatically connects to the wireless network named wp_master after booting. After the network is connected, the device will upgrade and deploy according to the firmware and configuration protocol and path delivered by the DHCP server.
