Why is the Online Light Blinking on My Spectrum Modem?
For your reference, here’s what it means when your modem is showing different color codes:
- Blue (Solid) – Your modem is running the way it was intended, operating on a DOC SIS 3.1 Bonded State.
- White (Solid) – Your modem is running the way it was intended, operating on a DOC SIS 3.0 Bonded State.
- Flashing Blue and White – Your modem is still working to establish an online connection.
- No Light – Network access is denied or unavailable.
Why is the Spectrum Modem Online Light Flashing White and Blue?
When your modem starts to flash white and blue lights it means that it is unable to get a network connection going.
This may be temporary (your modem might be powering up for the first time, powering up after a power outage, etc.) or it may be permanent.
Temporary: Temporary issues will generally sort themselves out all on their own. You might just need to let your modem sit for a moment or two.
Permanent: Permanent issues, though, where the white and blue blinking lights never seem to stop (even after a couple of minutes) generally mean that you have connectivity issues that need to be sorted out.
You might be dealing with a couple of problems specifically, including:
- There’s a problem with the high-speed internet node from Spectrum in your area.
- The modem you have is faulty equipment.
- The cables you’re connected with are faulty.
Here’s how to address those issues to get your modem back up and running again.
How to Fix Spectrum Modem Online Light Blinking Issues
The very first thing you’ll want to do to fix a Spectrum modem online light blinking issue is double-checking all of your connections.
1. Check the Connections
Start by checking to confirm that your modem is plugged into the wall, that it is getting plenty of power, and that none of the power connections are loose. You’ll also want to check the outlet or power strip that the modem is plugged into is in good working order, too.
After that, you’ll want to have a look at the other connections.
2. Check the Cables
Check the coax cable that brings the internet into your modem, making sure that it is tight, secure, and that there are no obstructions between it and your modem. Make sure that the cable itself is in good working order and shows no signs of obvious damage or degradation.
If you have any damaged cables (or cables you even suspect could be damaged) swap them out. They are super affordable and this is a really easy fix. You can also upgrade to better quality cables for a more stable connection and improved longevity.
3. Check for Local Outage
A quick search for the Spectrum Outage Information and Troubleshooting page on their site will let you know if the internet services are down and that’s why your router is blinking and not connecting properly
If the service is good but you still see a blue/white light that (almost always) means that you have a different problem on your hands.
4. Use a Different Coaxial Wall Outlet
You might even want to try a different coaxial wall outlet. Sometimes there are problems behind the walls that you can’t spot, including age issues, damage from rodents, or other problems buried under the drywall.
Try a different coaxial connection to see if that makes a difference.
5. Soft Reset Your Modem
Simply unplug the power from the wall and then wait for about 2-3 minutes. This gives your modem plenty of time to power cycle down, guaranteeing that there’s no energy left inside the hardware and letting it soft reset.
Plug everything back in after a few minutes and wait to see what happens. If you get a solid blue light you are off to the races, but if your modem continues to blink you’ll know you need to move on to something else.
Tip: In case there are batteries in the modem, then you need to remove them too during the reset process.
6. Reset Your Router
In the previous step, we mentioned resetting your modem. If you are using a separate modem and a router, it is important to reset the latter to be on the safe side. Follow these steps:
- Disconnect the power cable from the back of the router.
- Wait for 1-2 minutes.
- Plug the power cable back in.
- Allow the router about 2 minutes to re-establish the connection.
7. Reset the Modem via My Spectrum App
Another thing to test out is to reset your router through your Spectrum app. If there were some software issues on their end, that should help tackle the issue.
- First, you will need to download the My Spectrum App and log in.
- After that look for the ‘My Account’ tab.
- Select the “Services” icon and choose “Internet”, Select your router and go to ‘Restart Equipment‘.
- Click the “Restart” button to finish the process.
8. Restart the Gateway
If you happened to have a combination of a modem and a router, it is very important you reset both of them as previously mentioned. Follow these steps:
- Turn off the switch connected to the gateway.
- Take the batteries out.
- Wait for about 5 minutes.
- Put the batteries back in.
- Connect the switch to your device.
- Wait for 1 minute.
- Turn the switch on.
- Allow your device enough time to establish the connection.
9. Reset the Cable Box
If you have tried all the methods we described but still can’t get your Spectrum router the work properly, you can go ahead and restart the receiver to see if it was the culprit.
- Unplug the power cable from the back of the cable box.
- Wait for 1-2 minutes.
- Plug the power cable back in.
- Allow the cable box about 2 minutes to re-establish the connection.
10. Contact Spectrum
Now might be the time to contact Spectrum customer support directly.
This is a step of last resort, but sometimes it’s necessary. Ask them to try and run a diagnostic test on your connection, just to see if there really is something wrong with the internet coming into your home and not just the modem itself.
If the problem persists, though, ask that they swap out your modem for a different piece of hardware. You shouldn’t have to worry about any issues after that! Check out the list of the Best Streaming Devices on Amazon now!

At the very worst they’ll have to swap out your existing modem for a new one – one that hopefully works right out of the box!
