Cables problem

A cable problem is also a common reason for red light on my Spectrum router or Fios router blinking red. 

Any damage and broken connectivity cables can affect the transferring ability.

Let’s check out the cable linked to the router's Internet port. Don't forget to inspect its end connectors for damage as well. 

The plastic end connectors of an ethernet cable are the most commonly damaged area.

They have a clip that secures the cable to the port, and if this breaks, the connection will be unreliable.

Your cable can be damaged or broken leading to Internet issues

Modem problem

Similar to router problems, if there is a failure connection between your modem and your devices, red light on Wifi router Spectrum appears. 

Heat is one of the main causes of modem failure.

Each modem is designed to own a cooling fan and you can help mitigate this factor by cleaning dust from your modem on a regular basis and keeping it in a well-ventilated area.

Nonetheless, heat will always contribute to a modem's eventual failure.

Modems such as popped capacitors can also fail due to internal component failure. 

Heat buildup, exacerbated by dust, is bad for electronics, but even if the heat problem is addressed, these components may fail due to age.

Modem problems

Incompatible network frequency

Incompatible network frequency is also a common main reason leading to the Spectrum router turning red.

Routers operate in mainly 2 frequencies: 2.4GHz and 5 GHz.

When the chosen frequency is too busy or has something abnormal, the connectivity network will be damaged.

Moreover, may your router is designed to work at just only 2.4 GHz.

When you try to connect to 5GHz, it’s incompatible and then the Internet issue happens.

Hardware problem with modem/router

A hardware issue with your setup may also result in your router's red light, including Spectrum and EERO red light.

Hardware issues are uncommon, but an older computer or tablet's network adapter may stop working unexpectedly if it overheats.

To get a better online experience, you may need to repair or even replace a new one.

Similar to the connection between router and modem, you need an ether cable to link PC devices and the router.

The ethernet cable connecting your PC should be plugged into one of your Spectrum router's yellow slots and the LAN ethernet input of your PC. 

Check out the connection between the router and the PC devices

If everything is properly connected, try switching the ends of the ethernet cable to ensure that it is not twisted or under pressure. 

Inspect the input ports, and if everything is in order, restart your computer and check again.

Thus, changing the compatible frequency can be a good tip to fix the red router light.

  • How to access the router settings page?

Firstly, you need to know “what’s your IP?”. 

You can Google this question to get the result quickly and easily.

Open a web browser ( Chrome, Safari, Firefox…), paste your IP address into the address bar, and enter the Control Panel.

Type the admin and password to log in to the page.

Then, you select the network tab and configure the Internet network band from 5 GHz to 2.4 GHz. 

Check compatible network frequency

Note that when you visit the Software update tab, let’s check available firmware to update.

Make sure you update the latest version before you continue.

Check if there is Internet

Aside from the internal connections, an external connection also comes to your router.

If this connection suddenly stops, your Spectrum red light on Wifi router is an alert.

The data usually comes with a black Internet cable that should be connected to your modem (or, if you don't use a modem, directly to your router). 

The best way to see if there is the Internet is to plug the Internet cable directly into your PC's LAN input.

If it is, you can run a Wifi speed test to test the connectivity.

If the direct connection fails or you have slow Wifi speeds, you are most likely not receiving any Internet at all. 

At this point, the best thing to do is contact your ISP and ask for assistance.

Check if there is Internet
