Spectrum Router Red Light (EXPLAINED & How To Fix?)

There are plenty of reasons why Spectrum routers red light blinks, we will explain all the reasons and show you how to fix them quick.

Spectrum (Formerly Time Warner Cable) has been in the middle of plenty of controversies for quite some time now. This is due to their horrible customer service, constant internet outages or slow speeds… But today I would like to focus on something different – Spectrum’s cable modem or “routers”.

Spectrum cable modems – also known as Arris routers – are popular for two reasons: They are cheap & they are easy to obtain.

Unfortunately, even though these devices provide cheap access to the internet, their quality has not been consistent throughout the years. Each year Spectrum will release new revisions of their popular Arris TM1602A router – however, their quality for internet service hasn’t been the same.

Today I will be discussing two very common issues Spectrum users are facing with these routers. These are: Blinking red light & blinking blue light. So let’s get started!

In general, Spectrum router red light blinking is caused by a loss of internet connection. ISP providers with high bandwidth demands often have some subscribers suffer from loss of internet connection as the use of data in certain hours of the day surge.

Spectrum in particular has a reputation for using booster technology to balance out their bandwidth distribution which often leads to some customers losing internet connection.

Spectrum Router Red Light Issue Explained – Why is it Happening?

When the Spectrum Red Light starts to blink red, it means that the modem cannot connect to the internet.

Most often than not, this is usually due to Spectrum’s over-used and over-priced bandwidth. When their network gets overloaded by too many people, you will be required to wait until they fix it… But there is a quick and easy way out of this! Just do as follows:

First,   unplug your modem and router from power and wait for at least 10 seconds. – Now plug the modem back in, wait until it’s done booting up (takes less than a minute usually) and then plug in the router as well.

After following these steps, you should be able to get online without any issues.

Spectrum Router Blue Light Issue Explained – Why is it Happening?

The Spectrum blue light issue is a little bit different from the one above since the router most often than not will start to blink blue after turning it on with a wired connection.

So if you turn on your Spectrum modem and you notice that the blue light is blinking, it means that there is no internet connection – This can be due to many reasons, but the most common one would be Spectrum’s overused network.

Just like with the red light issue explained above, you can solve this by unplugging both your modem & router from power and then turning them back on again after 10 seconds.

In order to avoid these issues from occurring, I would recommend you getting a modem/router combo instead of a single device – Doing so will save you a lot of money in the long run!

The one that I have been using for about 3 years now is Zoom 5345 and it works great with Spectrum. You can purchase it from Amazon.

Spectrum Internet Outages & Slow Speeds Explained

Now that we have covered the two most common Spectrum modem issues, I will now explain why their internet is constantly going out and how you can fix this.

Spectrum apparently uses a technology called PowerBoost which allows them to oversell their bandwidth – But this comes at a very high price – Constant internet outages.

There is one reason PowerBoost exists and that’s because Spectrum oversells their bandwidth which makes them the only ISP in the world to do so.

If you want more information on this topic, I would recommend reading the other articles where I have covered this topic at length including reputable ISP user experience report sources

Unfortunately, since Spectrum is the only ISP in the world that uses this throttling method – There isn’t much you can do about it.

The only thing I would recommend at this point is switching to another ISP or buying your own modem/router and using that instead of their one… But doing so will require some networking knowledge.

Unfortunately, Spectrum doesn’t allow you to block certain devices from your network without getting a plan upgrade – But if this is something that you require, I would recommend going with another ISP or contacting them and asking for a monthly fee to have the feature.
