- Can you get into the menu of the device?
- Is the LAN cable still connected to the device?
- Check the connectivity of the internal IP (ping the internal IP address)

- 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 192.168.1.201”
- If it is ok, you will see a line "Ping statistics for 192.168.1.201: 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.

- In the new box that appears on your screen, type the word “ping” followed by an IP address or a domain name. Press enter.
- 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
- 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.
