5 Ways to Fix The Spectrum Modem Blinking Blue

If the multiple light statuses and the causes behind the Spectrum router blinking blue are out of the way, let’s jump into the solutions.

However, before that, we suggest restarting the Spectrum router at least once. Rebooting an electronic device is pretty effective in most cases. And if a simple reboot fixes the blue light issue, you don’t need to go through all the hassle. So, try it. If it doesn’t work, the most effective solutions are listed below.

1. Check the Connecting Cables, Whether They are Loose or Damages

Let’s start with the inspection of the connection cables. As we mentioned earlier, this happens when the router trying to connect to the internet but failing miserably. So, start by checking the ethernet cable that connects the router to the modem and the coaxial cable that connects the wall port to the modem.

Regarding the ethernet cables, you should hear the trademark snap sound when properly connected. If you don’t hear it, the cable is likely not connected. On the other hand, the coaxial cable is thicker and has a metallic end. If the pins of the metallic end are slightly bent, maintaining a strong connection would be an issue.

As you inspect the cables, disconnect and reconnect them properly. While you are doing it, check the pins as well.

That’s all! If there’s no visible damage to the connecting cables, move on to the next solution.

2. Power Cycle the Spectrum Router

Similar to any electronic device, you can face random glitches during regular tasks, even with Spectrum routers. So, the easiest way to fix the Spectrum router blinking blue is through a power cycle.

3. Plug the router back into the power source while it is still connected to the modem.
4. The blue light should start blinking, meaning the router is trying to connect to the internet.
5. The blue light should turn stable after two minutes, meaning the router has established the connection.

If the router fails to connect to the internet, the blue light keeps blinking even after five minutes. You need to look into a different solution.

3. Re-Sync the Spectrum Router and the Modem

If the modem is connected to the internet and showing stable light but the router still blinking blue, there’s likely no communication between the two devices.

So, in this case, you have to re-establish the communication between the router and the modem to ensure a stable internet connection. So, here’s what you need to do.

1. Unplug both the modem and the router from the power source.
2. After that, only connect the modem to the power source. (You need to wait for the blue light to turn stable)
3. After that, plug in the router. And ensure to connect to the modem properly.
4. Now, you need to wait a few minutes, giving the devices time to synchronize.

After doing all that, you should have a stable connection, and the blue light on the Spectrum router should turn stable. The entire process takes about a minute or two. If it doesn’t work, update the router firmware.
