If you are experiencing an unstable internet connection despite having a running network, then your Spectrum router may be having issues that need to be fixed.
This can be frustrating especially if you have to make monthly payments for the router and it is not working.
So, is your Spectrum router blinking blue? A blinking blue light on your router shows that there is something wrong with it and you need to check it to see what is going on.
The problem could range from a damaged cable to outdated firmware.
How the blue light is blinking can tell you a lot about the issue or status of the router. For example, slow blue blinking shows your router is booting up, while consistent blue blinking motion suggests there are connectivity issues.
Continue reading to understand the meaning of a Spectrum modem blinking blue, the reasons that cause the blinking, and how you can fix it.
What Does It Mean When A Spectrum Router Blinks Blue Light?
When your Spectrum router is blinking blue, it shows that it is trying to establish an internet connection.
Once the router has connected to the internet, the blinking blue light will stop and then there will be a solid blue light. This whole process can take up to two minutes.
However, if the router is still flashing blue light and cannot connect to the internet, then you have to troubleshoot it.
But before fixing the problem, you should check which type of blue light is on your router and what it means as explained below:
- Slow flashing/blinking blue light – your router is getting ready to boot up.
- Keeps blinking blue – shows some problems with connectivity.
- Steady blue light – ready to receive WiFi signal as it is booted up successfully.
- Blue-red light – the router is in the process of updating firmware.
- Blue-white light – the router is trying to connect to the internet.
What Causes a Spectrum Router to Blink Blue?
There are various reasons for your Spectrum router to blink blue when it is not connected to the internet. They include:
- Router and modem synchronization issues.
- The cables are not properly connected.
- Spectrum system outage.
- Faulty router unit.
- Faulty connection cables.
- Bandwidth overload.
- Corrupt router settings.
- Router is overheated.
How To Fix The Spectrum Router When It Is Blinking Blue
The following are some of the things you can do to fix a Spectrum router that is blinking blue:
1. Check Connection Cables
If there is no network connection and the router is blinking blue, you should check the connection cables.
These refer to the ethernet cable that connects the router to the modem as well as the coaxial cable that connects the wall port to the modem.
When it comes to ethernet cables, the snap sound that you normally hear when you insert it may sound less convincing.
This is because the snap pin of the cable is becoming more malleable which makes it hard to keep a connection stable and secure.
The coaxial cable is a thicker cable with a metal end that is shaped like a cylinder and is tightened by rotating it. The big problem with a coaxial cable is the pin in the metal.
If it is slightly bent, you will have problems maintaining a strong connection.
Whether it is the coaxial or ethernet cable that is causing the problem, you should unplug them from the port and plug it back.
Additionally, you should check the pins at the end of the cables to make sure that they are not broken or bent.
Finally, to have a proper connection ensure that the cable is tightly fitted into the ports at both ends.
2. Power Cycle Router
The next thing that you need to do if a Spectrum router is still blinking blue is to power cycle the router.
If the router cannot connect to the modem, the steps will help you to power cycle it and hopefully, you can fix the blinking blue light:
- Unplug only the router from the power source and leave it for about one minute.
- While still connected to the modem, plug the router back into the power source.
- A blinking blue light should appear, meaning the router is trying to establish an internet connection.
- The blinking light should turn to a consistent blue light after about two minutes, which shows that the router has established the connection.
If the router does not connect to the internet and the blue light is still flashing after five minutes, then you have to resync the router and modem as explained below.
3. Resync The Modem And Router
Even though the modem is connected to the internet, meaning you are seeing a consistent blue light on it, the router may be showing a blinking blue light because there is no communication between the two devices.
Resyncing the router and the modem will ensure that the router establishes its network connection. Follow the steps below:
- Unplug the modem and the router from the power source and leave them out for 30 seconds.
- Next, plug in the modem only and wait for the ‘power’ and ‘online’ blue lights to turn solid.
- Then, plug in the router and make sure you connect it to the modem using the cable.
- Give it a few minutes and the devices will be synchronized. Once this is done, the router should have an internet connection and it should have a solid blue light.
- Now you can access the internet through the wireless network that the router provides.
This whole process can take up to two minutes, but it is necessary that you wait longer to see whether the blinking blue light on the router has stopped or not. If it has not stopped, you should reset the modem before connecting it to the router.
4. Reset The Modem
As explained earlier, the modem and the router need to be in communication for the router to have a connection and not have a blinking blue light.
If resyncing the modem and router did not solve the blinking problem, then resetting the modem first and then setting it up with the router could be your way of fixing the problem.
To reset the modem, press the reset button and hold for 30 seconds until the blue light which is next to ‘power’ starts blinking, then you can release the button.
The reset will be completed once the two solid blue lights appear on the modem, which means it is online.
Now you can turn on your router and the blinking blue light should be gone, then connect it to the modem. However, if the blue light is still blinking, then there could be other issues with the router that needs fixing.
5. Soft Reset The Router
Another way of fixing a blinking blue light on a Spectrum router is to do a soft reset using the following steps:
- Download the ‘My Spectrum’ app on your phone then open it.
- Log in to your account then click on the ‘Services’ tab.
- Open ‘services and equipment’ which is under the Services tab.
- Select your Spectrum modem router and click on ‘Experiencing Issues’.
- Finally, click on ‘Reset Equipment’ and allow it to finish the process.
6. Update Router Firmware
If you can still see the blinking blue light after resetting the modem and router, then you should update your router’s firmware. An outdated firmware will have some bugs and fortunately updating it fixes the problem.
Most routers can automatically update firmware, but sometimes the option can be disabled by default, therefore, you should manually update the router’s firmware using the following steps:
- Log in to the admin portal on the ‘My Spectrum’ app.
- Then go to the System settings section and check if there is any update available.
- If there is one, download and update it.
- Make sure that you turn on the Auto-Update option so that any updates will be automatically updated next time and you do not need to do it manually.
7. Check For System Outage
When there is a Spectrum system outage in your area, it can be frustrating. Whether it is the first time set up or whether the router was working then it gets disconnected and cannot reconnect as indicated by the blinking blue light, check for your local or wide system outage.
It is obvious that if there is a system outage when you are experiencing this problem, it will persist. However, if this has been a long-time issue, then it could not be because of your system’s downside issue.
The following steps are how you can check if there is a wide or local system outage with the Spectrum network:
- The best way to check is by going to the official support website and checking the Spectrum outage report page. There will be a prompt asking you to sign in.
- Once signed in with your phone number or email, you can chat with an agent inquiring about a system outage in your area or if it is widespread across the service.
- If you are in an outage try reconnecting your router later when there is no outage and you should see the blinking blue light turn to a solid blue light indicating a successful connection.
- If you are experiencing no system outage and the blinking blue light does not stop, you may need to replace the ethernet cable or coaxial cable.
8. Turn Off Your Antivirus
Antivirus is important because malware is in every corner of the internet. However, when there is a digital bodyguard, the antivirus can limit some of the things it allows. This might be your router and the ability to connect to the internet.
To find out if this is the issue, disable your antivirus software. During this moment avoid using the internet. Then take a few minutes to allow the router to connect.
After about five minutes, see if there is any change in the blinking blue light, if there is none then eliminate the antivirus from the list.
9. Limit The Number Of Devices On The Network
Your Spectrum router might be overloaded with many devices on the network. This makes the router heat up resulting in a slow internet connection.
Therefore, you need to disconnect any unwanted devices to prevent overloading the bandwidth and allow your Spectrum router to support the devices it can without issues.
10. Change The Router’s Location
If your router gets heated up quickly, change the location to a cooler place. The router can be overheated if it is connected to so many devices.
Place your router away from direct sunlight and enclosed spaces, as this also causes overheating which then disrupts the internet connection.
11. Get A Good Replacement Cable
An ethernet cable and coaxial cable are required to connect your Spectrum router and modem to the internet.
If both cables are faulty, the Spectrum router with continue blinking blue light because of a lack of connection.
The coaxial cable connects modems to the outlet of the wall helping to connect the Spectrum network.
When they are successfully connected the modem has two solid blue lights that is one indicates power and the indicates that the modem is online.
You may need to replace the coaxial cable if the blue light found next to the online label is blinking. If the port is faulty plug the cable into a different wall port.
The ethernet cable could have a problem if the modem is showing a solid blue light and the router shows a blinking blue light. In this essence, the ethernet cable needs to be replaced with a quality cable, especially one that has secure fits.
Some users have reported that replacing the coaxial cable assisted in fixing the blinking light problem on the router while other users reported the same for the ethernet cable.
12. Replace The Router Or Modem
There is an issue with your router when the modem is showing a solid blue light but the router still blinks blue. Likewise, when the modem doesn’t show the solid blue light then the modem has an issue.
Sometimes the modem and the router may be incompatible which makes the router not recognize it.
If the router and the modem are under warranty or you just bought them, you can return them to request a replacement at the store or either buy a new router or modem compatible with Spectrum.
Users usually report the Spectrum router stops blinking when the router or modem is replaced. However, it is usually when the router is replaced.
13. Contact Customer Care For Support
If you have tried all the above options and your Spectrum router continues blinking blue, then your final option is to call Spectrum customer care to help you with the issue.
An expert from the service provider will either provide a solution or help you get a replacement.
This is important especially if you are paying monthly for the router as it should work without any issues.
Once you contact them, give them details of the problem and the things you have tried to fix it so that they will know what to do.
Final Words
Hopefully, you are now clear on the reasons why the Spectrum modems and routers can have a blue blinking light, and the steps you can take to fix it.
When your Spectrum Modem Router is blinking blue, the main cause of this is an issue with the internet connection.
However, the issue could also be linked to device overheating, bandwidth overload, or corrupt router settings.
Most of the fixes to the blue blinking light issue are within your control to solve. For example, checking the coaxial or ethernet cables, rebooting the devices, or updating the firmware.
Sometimes, the issue is out of your control, for example when there is a local internet outage. In these cases, you need to be patient, and wait for the internet outage to be resolved.
