  • Web password: 123456 (some batches have random passwords. Refer to the password on the nameplate)

V. Preliminary Preparation

  1. Set the computer to an IP address on the same network segment as the gateway LAN port. The gateway LAN port is: 192.168.2.1.
  2. Connect the computer to the gateway LAN port with a network cable
  3. Power on the gateway and wait for the Status light to illuminate
  4. Ensure the computer has a properly functioning browser installed

VI. Network Configuration

6.1 LAN Port Configuration (Static)

alt text

  1. Enter [Network Settings] → [LAN]
  2. Configure an appropriate IP address. Generally, it needs to be on the same network segment as the device address and serves as the gateway address for the device.
  3. Select Apply
  4. After application, you need to use the newly set address to log in to the device alt text

6.2 4G Wireless Network Configuration

  1. Insert SIM card (note that the SIM card must be installed while powered off)
  2. Enter [Network] → [cellular] alt text
  3. If using a dedicated card or customized card, you need to configure the APN (this case uses a standard IoT card, no APN setting required) alt text
  4. View the Signal indicator on the panel. Red - poor (signal value 0~10), Yellow - medium (signal value 11~20), Green - good (signal value 21~30) alt text

VII. Router User Management Configuration

7.1 Changing Username and Password

alt text
