Why is Cox Modem Blinking Blue?


Most people are used to the simple blink colors to indicate the status of their modems; red for an issue and green for “all good.” However, the confusion comes in when you come across a modem that blinks in all colors of the rainbow. One of those products is the Cox modem. So if you’re wondering why your Cox modem is blinking blue, read on.

If the light on the right side of your Cox modem is flashing blue, it might mean your device is on WPS mode, or it might be picking up either upstream or downstream channels. In this case, it’s losing its channels.

Whether you just bought the modem or you’ve owned it for a while, a blinking blue light should signal you to act. So let’s dive deeper into why your modem might be flashing blue and what you can do about it to restore your internet connection:

Cox Modem Blinks Blue Explained

Cox has an article online indicating all colors that you may see on your modem from time to time, and blue is one of them. The main reasons are explained below.

WPS Mode

WPS mode on your cox modem gets activated when you press the WPS button located on the top with the two dots; WPS mode simply allows you to connect to your device wirelessly without using your WIFI password. Your modem will continue to blink blue until your device is connected; you will see a solid white light once connected.

Your Modem Is Trying To Find a Good Connection

If you have recently switched internet providers, your Cox Modem might be blinking blue because it’s searching for the right signal. It looks for a solid, stable connection, clear of noise or other exchanges.

If your modem can’t find this signal within about 30 seconds, it will stop, and you should be back up to speed in no time.

Your Modem Has a Hardware Issue

If the connection is fine and your internet service provider does not have any issues, your modem may have internal issues. While this doesn’t happen frequently, it can cause problems upstream and downstream channeling, which may require some troubleshooting.

If you notice that other electronic devices in your home are having issues connecting to the internet, the hardware issue may need resolving.

You can avoid hardware issues by ensuring your modem is stationed in a safe place, free of moisture or the possibility of falling on the floor.
