A dead or off LED indicates a disconnected internet connection. Whereas an active or on light indicates the connection is available.

Common Frontier Modems Light Meaning

As you know, Frontier rents out modems to its customers. The most common models you’ll find with the service provider are from Netgear or Arris. Below is a breakdown of the status lights of these modems.

The blinking green light eventually becomes solid green. Lastly, the solid red power symbol indicates the modem is not functioning properly. Try reconnecting the power supply and wait until the light becomes solid green.

Internet Light:

The internet symbol looks like a world. An unlit one, of course, means that there is no internet connection. A solid red light indicates there is a problem with the internet. At the same time, a solid blue light shows a stable and ready-to-use connection. 

Broadband Lights:

Arris modems have wave-like symbols which represent broadband. These blink in three colors: green, solid green, and red. The red light means the broadband isn’t working. Blinking green indicates a loading gateway, while solid green means a stable WAN connection.

Wi-Fi Lights:

Lastly, there is the Wi-Fi LED. It flashes yellow, green, and red colors. The yellow light indicates traffic motion, or in simple words, it means the connection is active but isn’t stable. The solid blue light indicates that the connection is stable and ready to use.

A flashing white light indicates the device is getting ready and updating the firmware. In Netgear modems, white light also indicates the reset mode. And a solid white light means the device is online.

Netgear symbolizes internet connection with a symbol of a space belt around a world. However, it has the same light color (white) as the power symbol. Unlit light indicates no internet connection, blinking indicates traffic motion, and solid white means the connection is ready to go.

Ethernet Ports Lights

Next, you’ll find the Ethernet port lights. They glow in amber color. The blinking light indicates that the traffic is moving in and out, but the device is not ready. Whereas the solid amber LED indicates the connection is good to use.
