  • 4 min read

Your router is the most important part of your house’s internet network. Without one, you won’t be able to receive any incoming WAN signals and distribute them over WiFi or ethernet. This also means that your internet will stop working if your router has an issue.

In this article, we’re taking a look at the Spectrum router blinking red error and what you can do to fix the problem.

What does the red blinking light mean?

Different routers have different ways of signalling if there’s an issue with the router or the internet line itself. On Spectrum routers, a red blinking light usually indicates you don’t have internet connectivity. This can happen for several reasons, including

  • An outage on your ISP’s end.
  • Physical damage to the coaxial internet line.
  • Issues with the router firmware.

How to fix this?

Here are six solutions you can try out to fix the Spectrum router blinking red issue. 

Restart the router

One of the first things you should do in these situations is restart your router. Restarting internet devices can fix seemingly random issues that cause connectivity problems, including the Spectrum router blinking red issue. Just turn off your router (and modem) and wait for a few minutes before turning it back on again. 

Check for outages

Another thing you should keep an eye out for are regional outages. If your ISP is facing connectivity issues, you won’t get any internet at your endpoint as well. Check the Spectrum outage page to see if the internet in your area isn’t working and if it isn’t, you can chat with Spectrum internet support to know how to resolve the issue.

Check for a WAN signal

Check your router or modem for a WAN connectivity signal. If you aren’t getting one, chances are you aren’t getting any internet connectivity from your ISP’s end and you should contact them to get the Spectrum router blinking red issue resolved. 

Try ethernet

Sometimes the issue might be in your router’s WiFi network. Try plugging in a device to the router’s ethernet port to see if you get an internet connection. If you do, your best bet is to reset the WiFi network and reconfigure it to get it working. 

Check the WAN cable for damage

If your incoming WAN cable is damaged, your internet connection will be disturbed. Check to see if the cable (usually coax) is properly connected and that there is no physical damage to the cable. If you find some damage, reach out to Spectrum support to get their help repairing or fixing the cable.


Factory reset the router

Most routers have a reset button at the back which will reset the router to its default settings. If you’ve misconfigured some settings on your router or have been impacted by a bug or virus, resetting your router can fix these issues. Do remember that you’ll have to reconfigure the router with the credentials given by your ISP. 

Reach out to Spectrum support

If all else fails, your best bet to fix the Spectrum router blinking red issue is to just get on a call with Spectrum support and get an in-field technician to come to help you with your issue.
