Step 1 shows connecting a coaxial cable to the wall outlet, Step 2 shows connecting the power supply to an electrical outlet, and Step 3 shows connecting an Ethernet cable from the modem to a computer or Wi-Fi router.
Step 1: Connect Coaxial Cable
Connect one end of the provided coaxial cable to an active cable outlet (wall jack) and the other end to the COAX port on the back of your Hitron CODA modem. Ensure the connection is finger-tight.
Step 2: Connect Power Supply
Connect the power supply to the Power port on the modem. Then, plug the power adapter into a standard electrical outlet. The modem will begin its startup sequence, which may take a few minutes.
Step 3: Connect to Your Device or Router
Connect one end of the Ethernet cable to one of the Gigabit Ethernet ports on the modem and the other end to your computer's Ethernet port or to your Wi-Fi router's WAN/Internet port.
Activation
After connecting the modem, allow a few minutes for it to power on and establish a connection. The indicator lights on the front of the modem will show connection status. Once the modem is online (typically indicated by a solid 'Online' light), contact your Internet Service Provider (ISP) to activate the device. You may need to provide the modem's MAC address, which is typically found on a label on the bottom or back of the unit.

Maintenance
To ensure optimal performance and longevity of your Hitron CODA modem, consider the following maintenance tips:
- Keep the modem in a well-ventilated area to prevent overheating. Ensure there is adequate airflow around the device.

Troubleshooting
If you encounter issues with your Hitron CODA modem, try the following troubleshooting steps:
No Internet Connection
- Ensure all cables (coaxial, power, Ethernet) are securely connected to the modem and the respective outlets/devices.
- Check the indicator lights on the modem. If the 'Online' light is off or blinking, there may be an issue with your ISP connection.

- Verify that your ISP has activated the modem on their network. You may need to call them to confirm activation.
Slow Speeds
- Ensure your internet plan supports the speeds you expect. Contact your ISP to confirm your subscribed speed.
- Check if other devices on your network are consuming significant bandwidth (e.g., large downloads, multiple video streams).
- Restart the modem and your router (if applicable).
- Ensure your computer's network adapter or router supports Gigabit Ethernet for optimal speeds, especially if you have a high-speed internet plan.
Modem Not Recognized by ISP
- Confirm the MAC address you provided to your ISP matches the one printed on the label of your modem.
