Understanding the Ethernet Port LEDs on Your Hitron CODA56 Cable Modem
The Ethernet port LEDs on the back of your Hitron CODA56 modem help you quickly identify your connection speed and activity status. Each Ethernet port has two small LEDs — one on the top and one on the bottom — that indicate link speed and data activity.
Top LED – Connection Speed Indicator
The top LED shows the speed of your Ethernet connection between the CODA56 and your connected device (such as a router, computer, or switch):
| LED Status | Meaning | Connection Speed |
|---|---|---|
| Off | The connected device supports only 100 Mbps | 100 Mbps |
| Green | The connected device supports 1 Gbps | 1 Gbps |
| Amber | The connected device supports 2.5 Gbps | 2.5 Gbps (fastest) |
✅ Tip: For the highest performance, your goal is an Amber top LED, which indicates a 2.5 Gbps Ethernet connection.
Bottom LED – Network Activity Indicator
The bottom LED shows network activity on the Ethernet port:
| LED Status | Meaning |
|---|---|
| Blinking Amber | Active data traffic is detected (sending or receiving) |
| Off | No data traffic is currently being transmitted |
Example
If the top LED is Amber and the bottom LED is blinking Amber, your CODA56 is connected at 2.5 Gbps and actively transmitting data — the ideal setup for the fastest speeds.
Troubleshooting Tips
If the top LED is off, check your connected device’s Ethernet port — it may only support 100 Mbps.
If you’re expecting 2.5 Gbps speeds but see Green instead of Amber, ensure that:
Your connected device supports 2.5 Gbps Ethernet.
You’re using a Cat5e or higher Ethernet cable in good condition.
The Ethernet port on your router or computer is set to auto-negotiate or supports multi-gig speeds.
