As their names suggest, these different lights are designed to show the current status of the Frontier modem router.
- The power light tells you whether your Frontier modem router has sufficient power supply. When you connect the router to a power source, this light should be up. This will happen regardless of whether you have connected the router or modem to the internet.
- The internet light indicates whether you have a proper internet connection. The internet light on the Frontier modem-router indicates the internet status only from the router’s perspective. This means that even if you have not connected the WAN port to the internet source, the router will still show no internet connection.
- The wireless light shows the status of the wireless network. This is a relatively more straightforward light because you can know whether Wi-Fi is enabled on your device.
- The LAN or Ethernet port lights change colors based on the devices connected via Ethernet cables. These lights are designed to give you an overview of devices connected through LAN or Ethernet. Depending on the model, these lights may also indicate the speed levels of the network.
- The USB light deals with any connected removable media. You can know more about the different colors based on the specific model.
- Lastly, the signal strength light helps you understand the strength of your wireless or wired signals. Depending on the router model, you may have different designs for this light. In general, you would find bars that indicate the signal strength.

When everything works fine, the Frontier modem-router lights are easy to understand and work with. You simply have to check the lights to ensure everything is on the right track. However, things change when you encounter Wi-Fi or wired internet issues.
We shall now explore each of these LEDs and the different statuses of these LEDs in regard to your internet connection.
#1 Power Light LED Meanings
The power light on Frontier modem and router devices has only two states:
- Solid green: This means that the router has access to a stable power supply and works fine.
- Off: This indicates that the router receives no power supply due to an issue with the wall outlet or the faulty power cable.
If the power light LED is off, check whether the router receives proper power from the outlet. You may also want to try disconnecting and reconnecting the power cable at both ends. Additionally, check if your house or office is experiencing voltage fluctuation issues. If so, get a UPS for the router.
#2 Internet Light LED Meanings
The LED status light is a bit more complex, with four different states:
- Solid green: This means that the modem or router is connected to the internet, and everything is working fine, including the internet infrastructure of Frontier.
- Blinking green: You see this light when setting up the Wi-Fi router or modem. It means the device is trying to connect to the internet.
- Solid amber: This indicates there is an issue with reaching the internet service provider. It could be a variety of topics, including hardware and software problems.
- Off: This means there is no internet connectivity at all. You see this light after a few minutes of the modem trying to connect to the internet with no success.
You don’t have to worry if there is a solid green light. However, if you see a blinking green light for a long time, you should try some solutions. For instance, disconnect and reconnect the power to see if the problem is resolved.

Similarly, a solid amber light could indicate an issue with the internet service provider. Check whether the infrastructure works correctly if it’s a wired fiber connection. You might face maintenance issues from Frontier, like with other internet service providers.
Updating the router firmware to the latest version is also a good idea.
#3 Wireless Light LED Meaning
The wireless light also has four statuses that you can understand:
- Solid Green: This color means that the Wi-Fi connection from the router or modem is active and that you can connect other devices to the network.
- Blinking Green: You will see this light when the wireless network is active but no device has been connected to the network. This might happen when you set up the wireless network for the first time.
- Solid Amber: Like the other lights, the wireless light will show solid amber when there is a problem with the wireless network. It could be a radio-level issue or something temporary.
- Off: This will happen when the wireless network is turned off. This might have been turned off from the admin panel or through the companion app.
If you come across a solid amber light on the wireless LED, you should:
- Restart the Router: This step can resolve many potential issues. Restarting the router can help the device reset any accidental changes and boot properly.
If you see the OFF status on the wireless light LED, you may need to manually enable the wireless network. To do this, follow these steps:
- Connect a Device via Ethernet: Use an Ethernet cable to connect a device to the modem.
- Access the Administration Panel
- Navigate to Wireless Settings
- Turn On the Network
These steps will ensure that the wireless network from the Frontier modem/router works fine.
#4 LAN/Ethernet Ports Light Meaning
Let me quickly explain what the different lights on the Ethernet port LED mean:
- Solid Green: This indicates that a fully-fledged Ethernet device is connected to the port and will operate at the maximum possible speed, such as 1 Gbps or 100 Mbps.
- Blinking Green: The blinking green light signifies that the port is actively sending and receiving network traffic.
- Solid Amber: This light appears when a low-speed Ethernet device is connected to the router. In this case, the operating speed of the connection will be either 10 Mbps or 100 Mbps.
- Off: When the light is off, the LAN port is not being used, or the connected device is inactive.
In most cases, you won’t face issues with these ports. But you should check the settings if you see the Solid Amber light even when using a high-speed Ethernet device. Similarly, if you see the Off light even when a device is connected, check the Ethernet cable for potential damage.
#5 USB Light Meanings
There are only three statuses for the USB light on your Frontier modem router:
- Solid Green: This means that you have successfully connected a USB device to the modem and that it is functional.
- Flashing Green: This indicates that the router is currently using the USB and data from the USB is being accessed for printing or other purposes.
- Off: The light will be off if no USB devices are connected to the Frontier modem or router.
In most cases, these lights do not cause problems with wireless or internet access.
#6 Signal Strength Light Meanings
While the signal strength light is not so common, it can be an excellent way to understand whether the modem or Wi-Fi receives a proper signal. Here are the criteria:
- Four Solid Green Bars: The device receives the optimal signal amount without interference, ensuring the best performance.
- Three Solid Bars: You will still have good performance from your router, but speeds might be slightly lower during high-intensity usage hours.
- Two Solid Bars: The connection is still present, but the experience may be intermittent and unstable, indicating moderate signal strength.
- One Solid Bar: This indicates a weak signal, and you may not have proper wireless or internet access without diagnosing and troubleshooting the issue.
- Flashing Bars: Flashing bars on the signal strength light indicate unstable connectivity around the router, suggesting a need for troubleshooting to improve the signal.
