Faulty, worn out, and damaged cable connections are a brewing pot of trouble. Besides causing this issue at hand, faulty cable connections may lead to Spectrum cable box error codes.

You can quickly troubleshoot your modem’s white and blue blinking light by double-checking your cable connections.

Ensure that not a single cable is damaged or worn out. In case of any damage to your cable, you’ll need to replace each one of them accordingly. If you cannot do an immediate replacement, get a reliable electrician to fix your cables for you.

Additionally, make sure your cables are plugged into their correct ports firmly and tightly. Detach your cable and re-attach them firmly and securely.

Double-check the coax wall outlet cable as well if it is damaged.

3.Power Cycle Your Connection

Perhaps your modem requires another round of powering up. And, performing a power cycle is a fundamental troubleshooting method you can use to remedy this problem and several other issues with your Spectrum devices.

Power cycle your devices in the following steps.

  • Unplug all your devices from the power source and unplug all the devices from each other.
  • Remove your modem’s batteries and leave everything like that for up to a minute.
  • Reassemble everything together, put the batteries back into your modem and plug your devices into the power source.
  • Allow your devices alongside your modem about five minutes to boot up. When your modem is ready to use, all LED lights will turn solid green.

Sometimes, you may experience signal reception issues (which cause your modem to blink blue and white) because you’ve placed your modem in an area with a low signal. Therefore, it would remedy the situation if you moved your modem and router to someplace with a better signal.

Important tips include:

  • Keep your modem away from your kitchen since appliances like microwaves can interfere with the signal.
  • Do not place your modem in closed spaces like cupboards or behind walls.
  • Place your modem in a central location in your house or place of work.
  • Place your modem to stand upright.

It is, therefore, necessary that you offload some devices from your network.

Log out the devices you are not using from your network and check if you continue to see your Spectrum modem blinking blue and white. You’ll also need to know if someone is connected to your Wi-Fi network without permission, so you can log them out and increase your network’s bandwidth.
