Now, that you have seen and understood what may be the reasons behind such an issue to occur. Next, let us have a look at what are the best possible troubleshoot fixes out there, to help solve the problem and establish a successful internet connection once more. 

Hence, without any further ado, let us straight away jump into the various solutions out there to fix the Spectrum modem flashing blue and white issues.

Fix 1: Power cycle your modem device

The very first solution you can try is to power cycle your modem. Here, all you need to do is simply plug off the device from the power supply for about 10 seconds or more, and then plug it back in.

Switch on the power supply and wait for a few minutes for the modem to complete its initialization process and connect to the internet. 

This method has proved to work for most Spectrum users out there facing the same problem, which may have been caused due to an initialization problem earlier.

Fix 2: Check for Spectrum network outage

The second method is not a fix, but rather an inspection to see if the issue is from your Spectrum ISP’s end and not on your end.

Once you are sure that the issue is on the provider’s end and not within your control. All you need to do is wait for a few hours, till Spectrum takes care of the issue on their end. 

To check for network outage, all you need to do is follow the steps as shown below:

  • Firstly, you will need to go to Spectrum’s official website.
  • Next, click on the Check Outages button as shown in the screenshot below.
  •  Once you click on the Check Outages button, you should be prompted with the Chat With Us box as shown below.
  • Here, select the “Am I in an outage?” option and then login with your user credentials and get your query answered. 

This way, you will be able to check whether the area you are in is experiencing a network outage or not.

Fix 3: Check and replace cables if damaged

Most often, if the cables connected to your modem are not connected properly or are damaged. Then, such an issue might easily occur.

To fix this, you will need to check whether there is any kind of loose connection or damage to the coaxial wires attached to your modem and plug it correctly if the connection was loose or replace it if the wires were damaged.

Once that is done restart your modem and check whether the problem still persists or not. 

Fix 4: Reset your Modem and Router

You can either reset your modem and router directly or do it with the help of the My Spectrum App.

With My Spectrum App

  • In order to reset your Spectrum modem with the help of My Spectrum App. You will need to first download the app by going to the following link.
  • Once the app has been downloaded and you have logged in to your account in the Spectrum App. Next, go to the My Account tab and click on the Services icon.
  • Then, choose the Internet option and select the router device you are using. 
  • Go to the Restart Equipment option and then click on the Restart button. Give it some time to restart and see whether the problem still persists. 

Directly Resetting the modem

This is true for both modem as well as router devices. At the back of each of the devices, there should be a button or hole to reset them. 

If it is a hole, then you will need to find a sharp pointed object such as a safety pin or a paperclip, and push it into the hole, press and hold it for around 10 seconds. 

Once that is done, release and take it out and restart your modem and router once again and let it reset and initialize on its own. After all that is done, check whether the problem still remains.

On the other hand, if your network device has a reset button. Then, similar to what you had done earlier, simply press and hold on the reset button for around 10 seconds and let the device reset on its own.


So, in this way with the help of any or even all of the above mentioned methods, you should be able to fix the problem of Spectrum LED lights flashing blue and white on your own. 

For some reason if by following all the methods as shown above, you are still unable to fix the issue on your own. Then, the problem might not be something with the initialization process or software. But, it may be related to the hardware. 

In such cases, if the problem is a crucial hardware fault or damage to the modem and other network device. Then, contacting Spectrum’s help desk for their expert support and help might be the best possible option as well as solution out there.
