For the most part, Spectrum modems and routers have a user-friendly design. Instead of creating a sense of confusion with multiple status lights, Spectrum goes for a single status light for its modems and routers. It’s convenient and makes it easy for non-tech-savvy people to operate the network devices.

    But, how do you understand the meaning of different Spectrum lights and resolve the problem? In this guide, I have covered everything you should know.

    Meaning of Spectrum Modem Lights

    The spectrum router red light is indeed a problem: no internet connection. Instead, if you see a standard blue light or a white light, it means the router is perfectly fine. You can also find other lights on a modem such as Ethernet, power, USB, Wi-Fi and online.

    Spectrum Router vs Spectrum Modem

    Depending on the Spectrum plan, you could have either a spectrum router or a spectrum modem. Even though you get a combined device sometimes, it is important to understand the differences between a spectrum router and a spectrum modem.

    Spectrum Router vs Spectrum Modem

    A Spectrum router is a name given to the spectrum Advanced Wi-Fi routers. These are all-in-one devices that make use of the simple design we mentioned in the introduction. It means these devices will only have a single light that you can refer to. You should also keep in mind that the spectrum router is responsible for receiving the internet signal from the ISP and making it a Wi-Fi network within your home or work.

    A Spectrum modem, on the other hand, is a device that receives the signal from the ISP and converts it into something your internet devices could understand. For the same reason, a spectrum modem may not always have a Wi-Fi module, and you might have to connect a third-party Wi-Fi router if you want a wireless network at your home or office.

    The number of status lights on these devices is not the same. Compared to a Spectrum modem, a Spectrum router does not have many lights. Instead, it has a single LED which changes color according to the status of the router. On the other hand, you can find various individual LED lights on a spectrum modem. I have covered all these lights in the upcoming sections.

    Types of Lights on a Spectrum Router (Advanced Wi-Fi)

    We will first take a look at the types of lights you can find on a Spectrum router, which is also known as Spectrum Internet Advanced Wi-Fi. As I said earlier, a typical spectrum router does not come with multiple LED lights, instead there is a single light that will change its color depending on the current status of the router or modem.

    Types of Lights on a Spectrum Router (Advanced Wi-Fi)

    Steady Blue Light

    Meaning: A steady blue light on your Spectrum Advanced Wi-Fi Router means everything is working fine. You should also have access to the internet without any issues.

    Action Required: None

    Blinking Blue Light

    Meaning: If the blue light is blinking, it means the Spectrum Advanced Wi-Fi Router has some trouble connecting to the internet. It could be due to network-wide issues or something specific to the modem.

    Action Required: you can try restarting the router and see if the problem goes away. If it does not, you might have to get in touch with Spectrum support.

    Flashing Blue/Red Light

    Meaning: If your Spectrum router is flashing red and blue lights simultaneously, it means there is something wrong with the router firmware. The ideal method is to wait for the firmware update or do it manually.

    Action Required: You can wait until the modem automatically downloads and installs the correct firmware from the official website, but it is also possible for you to manually install the firmware update using the Spectrum router dashboard.

    Solid Green Light

    Meaning: that if you have a new model of Spectrum router, you might not see a solid green light in the first place. But if you see one, it means everything is fine.

    Action Required: None

    Solid White Light

    Meaning: Some internet routers from Spectrum will also show a solid white light to indicate that you are connected to the internet. If you find that the light is not blinking, it means you have a stable internet connection.

    Action Required: None

    Blinking White Light

    Meaning: On the contrary, when there is a blinking white light, it indicates some issues with the internet. For some reason, your Spectrum router cannot connect to the internet, and it needs to be taken care of.

    Action Required: You might want to restart the router and get in touch with support

    Solid Red Light

    Meaning: The spectrum router red light is one of the most discussed situations out there. It indicates when there is no internet connection due to multiple reasons. So if you see a red light on your Spectrum router, you should be ready to follow some resolving options.

    Action Required: Multiple issues with the network or the router could be responsible for the solid red light. For the same reason, you have to check out multiple fixes, which can be found in my guide to fixing the spectrum router red light issue.

    Amber Light

    Meaning: An amber light on the spectrum router essentially deals with the status of the internet speed. It means that your router can connect to the internet, but the data speeds are not as fast as they should be.

    Action Required: You can consider restarting the router, but you will need professional support to increase the speed.

    Flashing Lights

    Meaning: All the lights flashing on your Spectrum router is not a good sign. It means there is something wrong with the router, and it cannot connect. There could also be situations of the modem updating itself and the process may take up to 10–20 minutes.

    Action Required: Wait for the modem to finish its update. If the update does not resolve the issue, you may want to factory reset the Spectrum router or wait for professional guidance.

    No Lights

    Meaning: If your modem has no lights, it probably means there is no power supply. Even if there are connection issues, the router should show at least one light. If everything is missing, you might have to get the router checked or replaced.

    Action Required: Get the router repaired or replaced.

    I have covered almost all the types of lights you would come across on a Spectrum Internet Router. Of course, you might find additional LED status lights on some specific routers, but the status of the main lights is in the order given above.

    Types of Lights on a Spectrum Modem

    We shall now explore the types of lights you would find on a spectrum modem and what these lights mean. For every type of light I mention, I will recommend the ideal situation and the things you should do if you find the light to be in a non-ideal situation.

    Types of Lights on a Spectrum Modem

    Ethernet Light

    This light is also called Link light and Act light. It basically should give you an idea about the LAN connection status.

    The ideal light activity is green, meaning that the Ethernet connection is working properly. But if you see that the Ethernet light is blinking red or green, you should check the cables and splitters for damage.

    Upstream Light

    The upstream LED light tells you the status of the data packets being uploaded from your router. It is one of the two parts that constitute your internet experience.

    So, if this light is solid red, it means upstream transactions are going as per the plan. If you see the light in a blinking or orange colour, you should contact support.

    Downstream Light

    The downstream LED light provides you with the status of data packets that the router is receiving from the internet. It is the other part of two types of transactions that make the internet experience as you want.

    The ideal status of the LED light should be green, which indicates that all the downstream transactions are active. But in non-ideal situations, this LED might show a blinking green or an amber light.

    Wi-Fi Light

    The Wi-Fi light on a spectrum modem indicates that the Wi-Fi network is active. It does not always mean that you have an internal connection. Instead, it tells whether the wireless network is switched on.

    If everything is working fine, the Wi-Fi light should be solid green. However, if the Wi-Fi light is flashing red, it means you do not have access to the wireless network.

    WPS Light

    The WPS light on a spectrum modem indicates the status of Wi-Fi protected setup. If you have enabled WPS clients or want to pair with a WPS client, you should keep an eye on this light.

    The steady light on the WPS icon means that the WPS system is active, however, when you are trying to pair a device or connect to the device, the light might be flashing or blinking.

    Online Light

    The online light on most spectrum modern modems indicates whether you’re connected to the internet. And you should keep an eye out for the solid green light in this part.

    Solid green is considered the standard option for most modems out there, but if you see a white light or a blue blinking light, you might want to check whether the spectrum internet is working.

    LAN Light

    Your Spectrum modem probably allows you to have multiple LANs. Therefore, you can use the LAN lights to understand which of these networks are active at the point.

    If you see a solid green light, it means you have a high-speed connection, offering the maximum speeds. But, if the light is blinking frequently, expect some impact on the transfer speeds.

    USB Light

    So, some Spectrum modems may also have a USB functionality and the USB light is designed to show whether you have connected a USB device to the modem.

    Battery Light

    If your modem comes with a built-in battery, you should also check the battery light. If it is green, there is a sufficient battery on the device. And if the light is off, the battery will be off.

    Power Light

    The power light is the easiest to understand on a Spectrum modem.

    If the power light is green, it means the modem receives power. If it is blinking or flashing, you should check the router and see what can be done.

    Telephone Light

    You might also find a telephone light on some Spectrum modems. This light indicates the status of a connected telephone, which could be a part of the package from the Spectrum.

    I want to mention that not all these lights will be present on all modems. You will find modems with multiple lights only if you are going for a specific high-speed internet plan from Spectrum. Otherwise, you would be bundled with the Internet routers that we have talked about.

    Potential Causes for Red/Blinking/Flashing Lights

    Multiple factors could be responsible for the red blinking or flashing lights that you see on a Spectrum modem or router. At the basic level, it may have something to do with the router or the modem itself. However, you cannot ignore the possibility of a network-wide outage.

    So, once, you have checked your modem for standard connection issues, you should also check whether Spectrum is having an outage. But if these methods do not work, you will have to try factory resetting the router or power cycling it for advanced functionalities.

    In my experience, whenever I see a red or flashing light on a spectrum router, I go ahead and restart the device. Even when the issue is not with the device, reconnecting to the spectrum networks solves most of the problem, and I’m back on the internet in a few minutes.

    Frequently Asked Questions

    What lights should be lit up on my modem?

    Ideally, the power, online and Wi-Fi lights should be lit up on your motor. These lights indicate the status of the internet connection, Wi-Fi network and power. And these lights should also be in a stable state, meaning that everything is working fine. If they are flashing/blinking, you might have to check for potential solutions.

    How do I reconnect my modem to the internet?

    The easiest way to reconnect your modem to the internet is to power off the device and power it on again. If you were facing some issues with the connection, you might have to wait for 30 minutes before you power on the device again. In the worst case, you can factory reset the router or contact the ISP.


    I believe this guide has helped understand the meanings of the different Spectrum modem and router lights that you have.
