Troubleshooting

If you encounter issues with your Arris DG3450, try the following steps:

• No Internet Connection:
  • Check all cable connections (coaxial, Ethernet, power) to ensure they are secure.
  • Verify the indicator lights on the front panel. If the Online light is off or blinking, there may be an issue with your ISP connection.
  • Restart the DG3450 by unplugging the power adapter for 30 seconds and then plugging it back in.
• Slow Internet Speeds:
  • Confirm your internet plan speed with your ISP.
  • Ensure your devices are connected to the appropriate Wi-Fi band (5GHz for faster speeds, 2.4GHz for wider coverage).
  • Minimize interference by moving the DG3450 away from other electronics.
• Wi-Fi Connectivity Issues:
  • Check the Wi-Fi indicator light on the DG3450.
  • Ensure your devices are within the Wi-Fi range.
  • Try forgetting and rejoining the Wi-Fi network on your device.
• Factory Reset: If problems persist, you may perform a factory reset. Locate the Reset button on the back of the device (often a small pinhole). Use a paperclip to press and hold the button for about 10-15 seconds until the lights flash. Note: A factory reset will erase all custom settings, including Wi-Fi name and password, reverting them to factory defaults.

If these steps do not resolve the issue, please contact your internet service provider for further assistance.
