Arris Modem Lights Meaning & What To Do When Blinking?

If the green online light is blinking, your modem is attempting to recognize your connection. It failed to establish your connection if it is blinking yellow or remaining a solid red color. You must contact your internet service provider to resolve this issue.

These lights may occasionally blink, and this frequently denotes a problem with your internet connection. There are numerous potential reasons why the Arris modem light might be blinking, including frayed cables, interrupted internet service, modem overload, and overheating.

Arris Modem Troubleshooting

Arris Modem Troubleshooting

If you can identify the light that is causing trouble, it will assist you in determining if there are any problems with the internet connectivity.

Power Light Solid Red

The modem is not able to fully charge. It could be due to an incompatible power adapter, a loose power connector, or another hardware problem.

The most straightforward method to test is by disconnecting the power cord from the device and connecting it to the outlet in the wall. Do this for a few minutes, then plug it back in.

If you don’t get the solution, then it’s not something that you can fix at home. Even if the issue isn’t fixed following an initial restart or forced reset, you’ll need to have the device checked by certified technicians.

Power Light Flashing Green

Your modem is currently in the process of booting up. Be patient! If it blinks for more than 5 minutes, disconnect your modem and try powering it back up.

Receive Light Blinking

If you have dual-band connectivity (2.4, five GHz, and 2.4) and the light on your receiver constantly blinks green, only one channel is operational. If you’re hoping for faster speed for uploads and downloads but are not seeing it, it may be because only the 2.4 GHz channel is in operation.

Usually, double-checking your connections and then restarting your modem can resolve this. If not, you can go into the administrator settings and determine the possibility that one of the two bands is mistakenly turned off in the settings.

Send Light Blinking

Also, if you’re using dual-band internet and notice the send light blinking green, uploading is only available on one channel. This could be the reason for slow connections if you use 5 GHz WiFi.

It is believed that the 2.4 GHz band is intended to support reliable speeds of upwards of 100 Mbps. However, because it’s the most popular frequency for wireless, it may be affected by interference in areas of high congestion of wireless networks (too numerous devices transmitting signals in that 2.4 GHz range). Therefore, if you’re using an ultra-fast internet connection (150+ Mbps), you must choose five GHz bands.

Check all connections, then reboot your router or modem, and if the problem persists, check the settings for your wireless.

Online Light Blinking

If the light for online is flashing green, it means that your modem is trying to register your connection. If it’s blinking yellow or a solid red, this means that it did not succeed in establishing your connection.

The issue is that you will have to contact an internet service company. In some instances, it is because of a MAC address that is not compatible. You should ask your ISP to explain why and if your device’s MAC address is being registered properly.

Any Other Lights

As we mentioned, the “link” light will often blink as you send and receive data; therefore, it’s not a reason to worry. If it changes to an orange or solid yellow hue, your connection is slow, so check all your connections.

If you notice that the “phone” or “2.4GHz/5GHz” light is off, no devices are attached to your router. Verify all cables that connect to the modem and your computer’s or phone’s WiFi settings to ensure you’re connected to the correct one.
