An Arris modem is an excellent way to get the most out of your high-speed Internet plan to maximize its benefits. Arris modems can handle speeds exceeding 1 Gig, making it hard to imagine they can cause problems until the Arris modem lights start blinking and turning off.
The light on every Arris modem gives you information about the status of your internet connection. There are typically four to six lights on the device.
The diagnostic tools make it much easier to troubleshoot your connection problems as they make the process much easier and ensure that you are back online as quickly as possible.
The following topics will be discussed:
- A description of the different Arris modem lights,
- Upon turning on, turning off, or flashing, what it means is,
- You can use the modem’s lights as a guide to troubleshooting the issue.
Let’s now delve into the deep end for more details.
The Arris Modem Lights
Let’s examine all the lights on an Arris cable modem. It is important to keep in mind that the lights on the modem may vary slightly depending upon the model.
The following lights should be present on most Arris modems:
Power Light
In the same way, you would expect, the Power light indicates whether or not electricity flows through the Arris modem.
As long as it is on, you have juice. Normally, if it does not work, you’ve got a problem. However, if your modem is unplugged, the issue should be resolved by reconnecting the modem.
Receive Light
Modems will display a light indicating whether they are receiving an internet signal. The light indicates that the modem is connected to the “download” portion. It is possible to see two different colors in this light if you have a dual-band modem:
- The blue light indicates that both bands (2.4GHz and 5GHz) receive signals.
- The green light indicates that a signal is only received on one band (2.4 GHz or 5 GHz).
Send Light
Your Arris modem’s “Send” light is its counterpart: it indicates whether your modem can send data over the internet. The one connected to your internet connection is the one for “uploading.”
There are two colors available for the Send light, just like the Receive light:
- Blue light indicates both bands are sending information
- Green lights indicate that only one band is transmitting information
Online Light
The green Online Light indicates that your Arris modem is fully functional. It’s easy to understand this light, just like you can tell if the power is on or off by the color of the light. In that case, you’ll need to do some problem-solving.
2.4 GHz Light
It signifies that your modem’s 2.4 GHz band is connected to the internet when the light is green.
5 GHz Light
This light indicates your modem’s 5 GHz band is connected to the internet when it is green.
Link Light
There won’t be a light on every Arris modem, so don’t be alarmed if yours doesn’t have one.
The “Link” light will be located beneath your newer Arris model’s “Online” light.
The flashing of lights indicates that data is being transmitted. There’s no need to worry – the blinking “Link” light is a good sign!
How to Resolve Wi-Fi Problems Using Arris Modem Lights
It is incredibly helpful to use the lights on your Arris modem to diagnose problems. You can find out where the problem lies with your wireless network. Pay attention to these signals from your Arris modem if you can’t figure out why your wifi doesn’t work:
| When You See. | It Means. |
| When the power light is off | There is a problem with your power outlet, something has come unplugged, or a breaker tripped it |
| Receive a blue or green flashing light | Unplugged or broken Ethernet, coaxial, and USB cables may cause. It is also possible that the modem needs to be reset. |
| When the online light is off | This modem doesn’t have a registered MAC address. |
| The online light is blinking yellow | Results are the same: the modem isn’t registered |
| The 2.4 GHz or 5 GHz light is off | The modem does not have any devices connected. |
Arris modem issues: Troubleshooting and solutions
Anyone experiencing trouble with wifi through their Arris modem generally has three options available to them:
1. Examine every cable
Cables like USB, Ethernet, and Coaxial may seem unimportant, and, in most cases, they are. If these cables are not completely plugged in, or if they are frayed or damaged, your modem won’t work.
The first step to ensuring that your wifi is functioning properly is to check your cables to ensure they are properly connected at the modem end and the other end (the wall, your computer, etc.).
The 2nd step you should take whenever you notice a blinking “Receive” light on your modem is to check whether the cables are properly connected.
2 Reset the Modem
The simple process of resetting your modem can often solve most issues with your modem.
If this doesn’t work, the modem isn’t at fault – there’s probably something else wrong – perhaps a disconnected cable or an issue with your Internet service provider.
Resetting your Arris modem can be done in two ways:
- Firstly, you can unplug it for 30 seconds and plug it back in afterwards. A time-tested computer tip that never fails!
- The second method involves pressing the “reset” button on the back of the unit. You can reset your modem by holding down this button for 10 seconds. This should fix your wifi issues immediately.
There is no difference between the two methods of resetting your router, so you can choose the one that makes sense to you.
3. Consult Arris Customer Support or your Internet Service Provider
If you are highly skilled in information technology, you can try to figure out how to fix the modem even if the lights are not working correctly. There is a chance that you may or may not be lucky – sometimes, even the best advice cannot bring your router back online, which means that you will need some assistance.
The “Online” light on your Arris modem must be checked by contacting a customer service representative if it flashes or does not shine. Your modem’s MAC address is either unregistered or unrecognized, which causes that particular light to flash or go out.
If you’ve tried everything else, then Arris or your ISP (internet service provider) are your only options for getting your internet working again. Their support team can assist if your MAC address is incorrect.
There isn’t a MAC address issue, and you are certain the modem is the issue since you have ruled out every possible source?
As a result, you may be forced to replace the modem, or at least begin the process of activating the warranty, as it is likely that the modem is faulty.
Conclusion
You can tell what’s happening with your Internet connection based on the lights on the Arris modem. Knowing what these terms mean can save you time when troubleshooting your internet issues.
Did you experience any problems using your Arris modem, or did the lights act in any way that confused you? Could you share any pearls of wisdom? Do not hesitate to express your thoughts.
