A router is without doubt the most important part of your home network. Without a router, you can’t really host a WiFi network for all the wireless devices in your house and a bunch of other basic networking that’s required to set up and make the full out of your internet connection.

That said if the router itself is having issues the rest of your network will also run into problems. In this article, we’re talking about why is your Spectrum router blinking blue and how you can fix the problem,

Why is your spectrum router blinking blue?

Since routers are often limited to LED lights to indicate their status, different LEDs and blinking patterns are used to communicate any issues to the user. In the case of your router’s LED blinking blue, more often than not it is to indicate the fact that there’s an issue with your modem. 

There are a number of reasons why that may happen, including the following:

  • Damage to the coaxial cable. 
  • Faulty or loose connections in the modern. 
  • Issues with the internet bandwidth. 

How to fix this?

Here are seven fixes you can try out.

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 blue issue. Just turn off your router (and modem) and wait for a few minutes before turning it back on again. 

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.

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 blue issue resolved.

Get another modem

Since the primary cause of the issue is the modem itself, switch to another modem in case you have one lying around to see if that fixes the problem, If you can use the router without any problems, your previous modem is at fault here and you should get a replacement from Spectrum in case you’re using the default modem provided. 

Check for outages

Another thing you should keep an eye out for is 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. 

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 blue 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.
