Red Light

The most common problems faced by customers of MediaCom Modems are red-light issues. There can be multiple reasons for the red light blinking. Some of them are as follows:

  • The modem is just turned on
  • It is trying to reconnect
  • The modem may have failed

When a modem is turned on, the first light that will appear will be a red next to the “power reader” after some time, the modem will ultimately connect, and the red light will change into a green one.

But in some cases, red light starts blinking instead of becoming green, which reflects the device has most likely failed and needs to be repaired or replaced.

Flickering Lights

Another common problem faced by the users is light flickering. Three significant reasons this can happen are:

  • The modem is stuck in a loop
  • An error or a bug
  • an outage at the back end

Lights flicker primarily on the light next to the “internet reader.” When you turn on your device and connect to the ISP server, the lights will start to flicker if the connection is unstable. On stabilizing, they stop blinking automatically.

In some cases, the modem falls into a loop of connectivity due to an error or a bug, and this loop prevents the light from stabilizing. Nothing to be afraid of because this problem is infrequent and common in old gadgets.

Most of the time, issue exists at the back end due to which device doesn’t receive the proper signals, and its lights start to flicker.

Yellow/Orange Light

This is the rarest issue on our list and only happens under specific conditions. Usually, when you see a yellow or an orange light, it is right after you turn it on, and all the lights flash for a moment.

If you do not have a computer attached through the WAN port, its light remains blank, a proper connection is marked by a stable green light. An Orange or Yellow light appears when you don’t have a good connection with the linked device, occurs due to a damage coaxial wire or broken connector.
