With this article, you are going to learn more about the common causes and easy fixes for a blinking green light on your Cox modem or router.
What Does a Blinking Green Light On a Cox Modem Router Mean?
When your Cox modem or router is flashing green, it usually means it is experiencing a bonding problem. This means that it is not able to bond with upstream channels due to the following causes:
- Problems with the signal splitter.
- The coaxial cables are damaged.
- Problems with the internet service provider.
How To Fix a Cox Router Blinking Green Light Issue:
Below are some of the things that you can do to solve a blinking green light on your Cox modem or router:
1. Check Coaxial Cables
The first recommended step to solving a blinking green light is checking whether the coaxial cables are operational and do not have any signs of damage.
Coaxial cables are prone to wear and tear after being used for a period of time.
If the cables are damaged, you should consider replacing them immediately. Additionally, you should check the cables if they are properly plugged in to the power source and your device.
You can unplug and then re-plug the cables and check whether the green light has stopped blinking.
2. Check the Power Outlets
If the coaxial cables are not damaged but the green light is still blinking on your modem or router, then you should check the power outlets as there could be an issue with the power supply.
To check whether the power outlet is working or not, unplug the modem or router from it and try connecting it to another outlet.
Then turn on the modem or router and check if the blinking green light has stopped.
Additionally, you can connect another appliance to the outlet to check whether it is functioning.
If the appliance is working well, then there is a problem with the modem or router. However, if the appliance is not working, then the outlet is the problem.
3. Check for Internet Outages
If there is an internet outage in your area, your Cox modem or router will not have a stable internet connection, hence the blinking green light.
Check Cox’s website to see whether there is an outage in your area as the company normally provide updates on the site if they are doing any maintenance on their network.
Also, you can ask your neighbor if they are experiencing the same issue with their internet connectivity. But this only applies if the neighbor is using a Cox network.
If the blinking green light is due to the internet outage, there is nothing you can do but patiently wait for Cox to fix the issue so that you can get back to a stable internet connection.
4. Check the Splitters
Cox modem or routers usually come with splitters which divided the connection into more than one link. This makes the internet connection run faster as the speed is optimized.
If there is a problem with the splitters, your modem or router will not have an internet connection, causing the blinking green light.
Sometimes the splitters can be overloaded which leads to overheating and slow internet connection.
If you do not know how to fix the splitters, you should hire a technician or contact the internet service provider to check and fix the problem.
If the splitters are not damaged but your modem or router is still blinking, then you should try a wired connection.
5. Update the Firmware
Your Cox modem or router has a software known as firmware which needs to be regularly updated. If the software is outdated, your modem or router will not function properly leading to a blinking green light.
Therefore, it is recommended that you check the Cox website to see whether your modem or router needs a firmware update. This will not only improve performance but also remove any minor technical issues.
The following simple steps will help you update your modem or router:
- Find the IP address of your modem or router on the label.
- Use a computer or phone that is connected to the internet to enter the IP address.
- Enter your modem or router’s username and password on the manufacturer’s website.
- Go to the update section and check whether there is a latest software.
- If there is, download it and install.
- Restart your modem or router.
If you are not able to access these instructions on the Cox’s website, you should contact their customer care and they will walk you through the process of updating the firmware.
Once you perform this update, the blinking green light on your modem or router should stop and your internet connection should be restored.
6. Check for Overheating
A blinking green light on a modem or router can also be caused by overheating of the device. Overheating of the modem or router can be caused by placing it in a location with direct sunlight or near appliances that emit heat.
The following are the steps to prevent your modem or router from overheating:
- Place your modem or router in a cooler location.
- Check the device for any dirt.
- Do not place anything on the modem or router.
- If possible, place the modem or router at the centre of the room to ensure it has enough space.
7. Perform a Power Cycle
If your modem or router is still blinking green at this point, then you need to do a power cycle on your modem or router. This is done by completely disconnecting the modem or router from the power supply.
This will allow your device to recalibrate and have improved connectivity and performance.
Perform a power cycle using the following steps:
- Turn off the modem or router.
- Unplug the power and ethernet cables from the modem or router.
- Give the modem or router about five minutes to rest.
- Plug the modem or router back to the power source.
- Turn the device on and let it reboot.
If doing a power cycle has solved the problem, then your modem or router will now stop blinking green.
8. Perform a Hard Reset
If doing a power cycle on your modem or router does not stop the blinking green light, you should do a hard reset.
A hard reset on your device will remove any customized configurations including your username and password and restore your modem or router to its factory settings.
Most modem or routers have the reset button located at the back of the device. Follow the steps below to do a hard reset:
- First, you should locate the reset button.
- Then, take a paperclip or toothpick and press the button for about 10 to 15 seconds.
- Give your modem or router about 15 minutes to automatically reset.
- Turn it on and hopefully the blinking green light is gone.
