Key Takeaways
- On both the Hitron CODA-4582 and CODA-4680, the ideal "everything is working" state is a steady blue or cyan light on the Downstream, Upstream, and Online indicators. Solid green is acceptable but means the modem is locked on fewer channels than it could be.
- Flashing lights almost always mean the modem is searching, registering, or transferring data. A flash that never goes solid usually points to a signal issue, an ISP outage, or a loose coaxial cable.
- Most light problems on the CODA-4582 and CODA-4680 are fixed by a 60-second power cycle, a tight coax connection check, or a 10-second factory reset.
What the Hitron CODA-4582 and CODA-4680 Are
The Hitron CODA-4582 and CODA-4680 are DOCSIS 3.1 cable modem and Wi-Fi router gateways issued by major cable providers like Rogers, Comcast Xfinity, and Cox. They are wall-mount or shelf-style units with a vertical column of indicator lights on the front. The CODA-4680 is the newer model and adds dedicated Ethernet, USB, and WPS lights, but both modems use the same color and flashing patterns to communicate status.
If you own one of these modems through your ISP rental and you are tired of monthly fees, you can replace it with a retail standalone modem like the Hitron CODA or browse our full DOCSIS 3.1 modem collection.
Hitron CODA-4582 Lights and What They Mean
The CODA-4582 has seven LEDs on the front panel: Power, Downstream (DS), Upstream (US), Online (@), 2.4 GHz Wi-Fi, 5 GHz Wi-Fi, and MoCA.

Troubleshooting Common Light Patterns
Problem: Downstream Light Is Flashing Green and Will Not Go Solid
The modem cannot lock onto a downstream signal from your ISP. This is the most common offline scenario.
- Unplug the power cable from the back of the modem.
- Check that the coaxial cable is screwed on hand-tight at both the modem and the wall jack. Loose coax is the number one cause of this problem.
- If you have a coax splitter, remove it and connect the modem directly to the wall jack. Splitters reduce signal strength.
- Wait 60 seconds, then plug the modem back in.
- Wait three to five minutes for the lights to cycle. The DS light should go from flashing green to solid green, blue, or cyan.
- If it still flashes, check your ISP's outage page or app. If there is no outage, call your provider and ask them to check the signal levels on your modem.
Problem: Upstream Light Will Not Turn Solid
The modem can receive a signal but cannot send one back. This often points to a noise issue on the line.
- Power cycle the modem by unplugging it for 60 seconds.
- Remove any coax splitters and connect the modem directly to the wall jack.
- Check the coax connector ends for bent center pins or corrosion. Replace the coax cable if either is present.
- If the upstream light still will not lock, your ISP needs to inspect the line. There may be a return path issue on the node.
Problem: Online Light Will Not Come On
Both the DS and US lights are solid, but the @ light stays off or keeps flashing. Your modem reached the network but failed to register.
- Confirm your service is activated. New customers must complete activation with their ISP before the Online light will turn on.
- Power cycle the modem for 60 seconds.
- If you swapped modems recently, call your provider and give them the MAC address on the modem label so they can provision the new device.
- If the light still does not come on, perform a factory reset by holding the recessed Reset button on the back of the modem for 10 seconds with a paperclip.
Problem: All Lights Are Off
The modem is not receiving power.
- Make sure the power adapter is fully seated in both the modem and the wall outlet.
- Test the outlet with another device, such as a phone charger.
- Try a different known-good outlet to rule out a tripped breaker or dead receptacle.
- If the modem still does not light up, the power adapter or the modem itself has failed. Contact your ISP for a replacement, or if you want to stop renting, see our best DOCSIS 3.1 modems for 2026.
Problem: Wi-Fi Light Is On but Devices Will Not Connect
The modem is broadcasting Wi-Fi but your phone or laptop cannot get online.
- Forget the network on your device and reconnect, entering the password from the sticker on the back of the modem.
- Confirm the Online (@) light is solid. If it is off, you have no internet to share over Wi-Fi.
- Try connecting to the other band. If 5 GHz fails, try 2.4 GHz, and vice versa.
- Log into the modem at 192.168.0.1 using cusadmin and the Wi-Fi password you set during EasyConnect setup. Confirm Wi-Fi is enabled in the settings.
Problem: Power Light Is Red or Flashing Red
A red power light usually means the modem is performing a firmware update or has detected a hardware fault.
- Do not unplug the modem for at least 15 minutes. Firmware updates can take 10 to 20 minutes and interrupting them can brick the modem.
- If the red light persists after 30 minutes, power cycle the modem.
- If it returns to red, contact your ISP to request a replacement.
How to Power Cycle a Hitron CODA-4582 or CODA-4680
A proper power cycle resolves most light issues. Follow these exact steps:
- Unplug the power cable from the back of the modem. Do not just turn off a power strip.
- Wait a full 60 seconds. This lets the capacitors discharge and clears the temporary memory.
- Plug the power cable back in.
- Wait three to five minutes without touching anything. The lights will cycle as the modem syncs with your ISP.
- When the Power, DS, US, and Online lights are all solid, the modem is back online.
How to Factory Reset a Hitron CODA-4582 or CODA-4680
A factory reset returns the modem to its default settings. Use this only if a power cycle does not fix the problem. Your Wi-Fi name and password will be erased.
- Locate the recessed Reset button on the back of the modem.
- Insert a paperclip or pin and press and hold for at least 10 seconds.
- Release the button. The modem will reboot and all lights will cycle.
- Wait five minutes for the modem to fully restart. You will need to complete EasyConnect setup again at 192.168.0.1 to set a new Wi-Fi name and password.
When to Replace Your Hitron Modem
If you have repeated outages, can never get the Downstream light to reach solid blue or cyan, or the modem keeps requiring resets, it may be time to replace it. Both the CODA-4582 and CODA-4680 use older Intel Puma chipsets, which have been linked to latency spikes during gaming and video calls. You can read more in our guide on Puma 7 chipset modems and their issues.
If you are renting one of these from your ISP, you can stop the monthly fee by owning your modem instead. Browse our DOCSIS 3.1 modem collection or read our complete modem and router lights guide for help understanding lights on any brand of modem.
Frequently Asked Questions
What does a blue light on a Hitron modem mean?
A solid blue light on a Hitron CODA-4582 or CODA-4680 means the modem has locked onto multiple bonded channels using DOCSIS 3.0. It is a good state. Solid blue on the Online light specifically means the modem is fully connected with both IPv4 and IPv6.
Why is the downstream light flashing on my Hitron modem?
A flashing downstream light means the modem is searching for a signal from your ISP and has not yet found one. Check that the coaxial cable is tight, remove any splitters, power cycle the modem, and check for an outage in your area. If it still flashes after five minutes, contact your ISP.
How long does a Hitron CODA-4582 or CODA-4680 take to come back online?
After a power cycle, expect three to five minutes for all lights to go solid. After a factory reset, allow five to ten minutes for the modem to reboot and re-register with your ISP. Firmware updates can take up to 30 minutes.
What is the default IP and login for a Hitron CODA-4680?
The default IP address is 192.168.0.1. The default username is cusadmin and the password is whatever Wi-Fi password you set during the EasyConnect setup. If you never set one, check the sticker on the back of the modem for the default key.
What is the difference between the Hitron CODA-4582 and CODA-4680?
The CODA-4680 is the newer model and has dedicated LEDs for Ethernet, USB, and WPS that the CODA-4582 does not. Both are DOCSIS 3.1 gateways with Wi-Fi, and both use the same color logic on their shared lights. The CODA-4680 also supports the EasyConnect setup wizard for easier first-time configuration.
Can I use a Hitron CODA-4582 or CODA-4680 with any internet provider?
No. Both modems are typically provisioned by a specific ISP, usually Rogers in Canada or Comcast Xfinity in the United States. They will not work on a different provider's network without being re-provisioned, which most ISPs do not allow on competitor hardware. If you want a modem that works across multiple cable providers, see our list of Xfinity-compatible modems or our best DOCSIS 3.1 modems for 2026.
Why is the Online light off but the downstream and upstream lights are solid?
This usually means the modem has connected to the cable network but has not been authorized for service. Either your account is not active, your provider has not provisioned the modem's MAC address, or there is a billing hold. Call your ISP and provide the MAC address on the back of the modem to confirm provisioning.
