  1. Check the device to see if it is workable.
    • Is the power on?
    • Can you get into the menu of the device?
    • Is the LAN cable still connected to the device?
  2. Check the connectivity of the internal IP (ping the internal IP address)
    • To know what internal IP address is set in the device, you can go to
      • Menu > Comm. > Ethernet > IP Address, or
      • Menu > Options > Comm Opt > IP Addr
    • To test the connectivity of the Internal IP,
      • Connect your computer to the same network of the device.
      • For Windows PC/Laptop
        • Open up the Windows taskbar.
        • From the taskbar, type “cmd” to show the Command Prompt Window. Click on it and you should now see a black box.
        • In the black box, type the word “ping” followed by an IP address, and press enter. For example, type “ping”
        • If it is ok, you will see a line "Ping statistics for Packets: Sent = 4, Received = 4, Lost = 0 (0% loss)"
      • For MacOS
        • Open up the MacOS Finder.
        • From the list of applications, scroll down until you see “Utilities.” Click it.
        • Near the bottom of the list, click on “Terminal.”
        • In the new box that appears on your screen, type the word “ping” followed by an IP address or a domain name. Press enter.
  3. Check the External IP
    • Connect your computer to the same network of the device
    • Open your Web browser
    • Type "IP address" into search engines such as Google to see your external IP address
  4. Check the Port Forwarding in the router
    • Is the Internal IP set for Port Forwarding same as the one you find in Step 2?
    • Is the Port Forwarding function enabled?
    • Has the External IP changed? If so, you may need to apply the Port Forwarding rule again.
