You might not always know which lights should be on and how they should behave. Don’t worry, though. In this guide, we have explained the different Arris modem lights and their meanings. To keep things simple, we will explain the **different statuses** and **meanings** of the different lights on an Arris router. ## Power Light The Power light is present on SURFboard SB6183 (**DOCSIS 3.0 modem**), SB8200/S33 (**DOCSIS 3.1 modems**), and SBG10/SBG8300 (**modem + router combo**) models from Arris. In addition, models from the TG and NVG series of the company’s modems will have a Power light. Here’s what the different statuses of the light mean: ### Power Light Is Off The Power light on the Arris modem stays off when the device is connected to a power source. If the light is off even with power connected, check the **power adapter**, **cable**, and **power port**. You should also check the socket once. ![Power Light](https://datafeature.com/wp-content/uploads/2026/02/power-light.jpg) ### Power Light Is Blinking Green The Power light will continuously blink while your **SURFboard** or **TG/NVG modem** is booting. This is quite normal and should continue for up to a few minutes. When the modem is fully on, the green light will turn solid, indicating stable power delivery. ### Power Light is Solid Green A solid power light on your Arris modem indicates that power delivery is working correctly. Your modem should be **working fine**, and even if there are other issues, the power delivery will not be responsible for them. ### Power Light is Red If the power light is solid red, it could indicate a **hardware issue**, such as **overheating** or **overloading**, and the device may not work. You may have to check the outlet or replace the Arris modem in your hand. You might need professional support here. ## Internet Light The Internet light is another common status light on many Arris modems. Some models include **NVG448BQ**, **NVG468MQ**, **NVG443B**, **NVG589**, and **NVG599**. Most of these models use **[DSL](https://datafeature.com/dsl-internet/)** or **[fiber connectivity](https://datafeature.com/fiber-vs-cable-internet/)**, and the light indicates the current status of Internet connectivity. ![Internet Light](https://datafeature.com/wp-content/uploads/2026/02/internet-light.jpg) Here’s how the Internet light behaves in different conditions: ### Internet Light is Solid Green/Blue Depending on the specific model, the Internet light could show a solid Blue or Green light. It indicates that the modem is successfully **connected to the ISP’s network** and has Internet access. On some models, you may see a blinking Green/Blue light when starting the router. It should turn solid in a few seconds. ### Internet Light is Solid Red A solid Red color on the Internet light means the modem cannot connect to the Internet. This happens when a **hardware/software issue** is preventing the modem from connecting. For instance, the **coaxial cable** from the outlet to the modem could be managed. In some cases, the modem may attempt a connection but fail. You can solve the problem by double-checking the cable, restarting the Arris router, and contacting the **[ISP](https://datafeature.com/best-internet-service-provider-in-usa/)** to check if they are facing an outage. ## Online Light Some models from Arris have an Online light as well. Some models include **SB6183**, **SB6190**, **SB8200**, **S33**, **TG1672G**, **TG1682G**, **TG2472G**, and **TG3442**. If you have any of these, here’s how you can interpret the way the Online light behaves. ![Online Light](https://datafeature.com/wp-content/uploads/2026/02/online-light.jpg) ### Online light is Solid Green The Online light on an address model indicates whether the device has been authenticated with the **Internet service provider**. A green solid light indicates the device is online on the ISP’s network; however, it does not necessarily mean you have internet access. If you cannot access the internet, even after seeing a solid green light for the **online status**, you may have to suspect an **ongoing issue with the ISP**. ### Online Light is Red/Off If the online light on your Arris modem is red or off, the modem is not online. It may happen due to **hardware or software issues**. You may need to contact the ISP to resolve the issue if reconnecting the cables doesn’t fix it. ### Online Light is Blinking In some cases, the online light on a **TG1672G** or **TG1682G** might be blinking. It means the modem is online, but the ISP hasn’t activated it. To solve this problem, you will need to contact your internet service provider and request activation. ## Upstream/Downstream Light Depending on your Arris modem model, you may find dedicated lights for Upstream and Downstream. Some models may call it “**Send light**” and “**Receive light**” as well. ![Upstream Downstream Light](https://datafeature.com/wp-content/uploads/2026/02/upstream-downstream-light.jpg) Here is what they mean: ### Receive/Send Light is Blinking The Receive and Send Light, also known as Upstream and Downstream Light, will blink while the device is scanning for an active signal. If the process continues for a long time, you may need to check the **[coaxial cable](https://datafeature.com/best-coaxial-cable-for-internet/)** or any other cable connected to the network. In typical cases, the light will keep blinking for a few seconds, and you should have a positive response. ### Receive/Send Light is Solid Green On **DOCSIS 3.0-powered Arris modems**, the Receive and Send lights will show a solid green when connected to the network. However, you should not expect maximum speed from these connections, as they are only for standard speed. This is not a problem, and you can leave things as they are. ### Receive/Send Light is Solid Blue A solid blue color on the receive and send lights means something else, though. This means the modem is using **DOCSIS 3.1** and is connected to the network at high speed. This means you should be able to access the maximum speed you purchased for your Internet plan. **Warning:** In real life, you can’t expect a high-speed connection from shared networks all the time. However, if you cannot have a **high-speed connection** at all, you should, of course, talk to your ISP and see if there are any problems. ## Broadband Light If you have Arris **NVG448BQ**, **NVG468MQ**, **NVG443B**, **NVG589**, or **NVG599**, you can find a Broadband light on the modem. This light should indicate whether your device is connected to the Internet using broadband. Depending on the ISP, your connection may be considered broadband only if it exceeds a specific speed threshold. Here’s what you can understand from different statuses. ### Broadband Light is Solid Green A solid green light for Broadband means you have an **active broadband connection** through the modem. You should have access to high-speed Internet, among other benefits. ### Broadband Light is Flashing Green The Broadband light flashes green when it **attempts to connect** to the network. You’d see this situation when you turn on the modem for the first time. However, if the process takes long, contact the ISP. ### Broadband Light is Solid Red A solid red light on the Broadband spot is not a good sign. It means your modem has **not detected** an active broadband connection. Please note that not all ISPs may have the right provision to show their connections as broadband. However, if you cannot find the light even when everything is connected, you can contact the ISP for assistance. ## WiFi Light The WiFi light is only available on Arris modems that support WiFi. As you know, some modems might not have this option, and there is no point in looking for one. If your modem has a WiFi light, it indicates whether the wireless connection is active. You can find the Wi-Fi light on Arris models like **SBG10**, **SBG8300**, **TG1672G**, **TG1682G**, **TG2472G**, **TG3442**, **NVG448BQ**, and **NVG468MQ**. ### Wi-Fi Light is Solid Red If you see a solid red light on the Wi-Fi indicator, the Wi-Fi connection is currently off or unavailable. It could be due to an internal setting or because other features disabled Wi-Fi in the first place. In this case, you can manually **re-enable Wi-Fi** or wait for the issue to resolve. ### Wi-Fi Light is Solid Green Some models may also show a solid green light when the Wi-Fi connection is active. It may depend on some cases. For instance, when there’s **incoming or outgoing traffic** via Wi-Fi, the light may flash rapidly. You would see a stable light otherwise. ## Phone Light The Phone light is generally found on Arris modems with the model names **TM822**, **TG862G**, **TG1672G**, **TG1682G**, **TG2472G**, **TG3442**, **NVG448BQ**, and **NVG468MQ**. These are modems that support phone setup as well as Internet access. Here’s what you can understand from the status of the Phone light. ![Phone Light](https://datafeature.com/wp-content/uploads/2026/02/phone-light.jpg) ### Phone Light Is Off If you don’t see any color on the phone light, it indicates that the telephone line is inactive. You might not have **set up a phone line**, or the connection may not be proper. ### Phone Light is Flashing Green A flashing green color on the phone light indicates an **incoming call**. The light will continue flashing when the phone rings and during the call. Of course, you don’t have to do anything here. ### Phone Light is Solid Green A solid green light, on the other hand, means the phone connection is active. It would remain solid green as long as the connection is active. ## 2.4 GHz & 5 GHz Light Modems like TG1672G, TG1682G, TG2472G, and TG3442 have separate lights for **[2.4GHz and 5GHz](https://datafeature.com/2-4-ghz-vs-5-ghz/)**. You can find these lights on modems with dual-band Wi-Fi connectivity. Two lights exist because you can enable or disable Wi-Fi connection on a separate band. Here’s what you can understand from these lights. ### 2.4GHz/5GHz Light is Flashing Green If the 2.4 GHz or 5 GHz light is flashing green, it means one of the devices is using WiFi on that band. For instance, if a smart TV is consuming a lot of traffic using the 5 GHz band, the 5 GHz light will flash. ### 2.4GHz/5GHz Light is Solid Green A solid green color on either of these lights indicates that the Wi-Fi connection is active; however, no devices are currently using it. You are unlikely to see this status, given how pervasive Wi-Fi usage is. ### 2.4GHz/5GHz Light is Off The 2.4GHz or 5GHz light may be turned off entirely if you have **disabled Wi-Fi on that band**. ## Wrapping Up I hope this guide provided some clarity on the Arris modem lights and their meanings. These understandings will, of course, help you fix the problem whenever you come across one.
