Troubleshooting Slow Speeds on Your Hitron CODA56 Modem

Troubleshooting Slow Speeds on Your Hitron CODA56 Modem

If you're experiencing slower-than-expected Internet speeds with your Hitron CODA56 modem, don’t worry. This guide will help you identify possible causes and walk you through steps to improve your performance.

Step 1: Use the Included 2.5 Gbps Ethernet Cable

The Hitron CODA56 Retail Kit includes a high-speed 2.5 Gbps Ethernet cable. To achieve the modem’s full speed potential, you must use this cable or an equivalent Cat5e, Cat6, or higher cable.
  1. Avoid older Cat5 cables, as they may only support up to 100 Mbps or 1 Gbps.
  2. The included cable is tested to handle speeds up to 2.5 Gbps, ensuring optimal throughput between your modem and router.
Action: Make sure the modem is connected to your router or mesh system using the included 2.5 Gbps cable or a similar high-speed Ethernet cable.


Step 2: Check the Ethernet Port Speed on Your Router or Mesh System

Your CODA56 modem may be capable of delivering 2.5 Gbps speeds, but if the Ethernet ports on your router or mesh system only support 1 Gbps, your overall speed will be throttled down.
  1. Check the specifications of your router or mesh device to confirm if it has 2.5G (Multi-Gig) Ethernet ports.
  2. If your equipment only supports 1 Gbps, that's the fastest speed you'll see—even if your plan and modem are capable of more.
Tip: Look for specs that mention:
  1. 2.5G WAN/LAN port
  2. Multi-Gig Ethernet support
  3. 2.5Gbps ports

Step 3: Restart Your Equipment

Sometimes, speed issues are temporary and can be fixed with a quick reboot.
  1. Unplug the CODA56 modem and router.
  2. Wait 30 seconds.
  3. Plug the modem back in and wait for all LEDs to stabilize.
  4. Plug in your router and wait for WiFi to return.


Step 4: Run a Wired Speed Test

To confirm whether the issue is with your modem or WiFi system, run a speed test using a direct wired connection.
  1. Connect your computer directly to the CODA56 using the included 2.5 Gbps Ethernet cable.
  2. Visit speedtest.net or your ISP’s speed test page.
  3. Compare the result with your expected plan speed.
If the wired speed is good but WiFi is slow, the issue is likely with your WiFi setup or placement.


Step 5: Confirm Your Internet Plan

Check with your Internet provider to make sure your plan supports speeds close to or above 1 Gbps. Some plans top out at 300 or 600 Mbps, which would naturally limit your performance.
Also confirm that:
  • Your modem is properly provisioned and activated.
  • Your ISP has no outages or network congestion affecting speeds.
