Let’s look at how to tell which Arris modem lights are needed to diagnose issues with your internet connection.

Power Light

The power light on Arris modems indicates if the modem has power and is starting up. A solid green power light means the modem is powered on. The power light on Arris modems signifies whether the modem is receiving electricity and able to start up. A flashing green power light indicates the modem is booting up. If the power light stays flashing for more than 5 minutes, it could mean the modem is stuck during the boot up sequence. A solid red power light signifies a problem powering up fully.

Send/Receive Lights

The send and receive lights on an Arris modem show the status of the internet connection for uploading and downloading data. A solid green or blue light means the connection is active in that direction. A blinking send or receive light indicates an issue with the connection for transmitting or receiving data. For modems using dual-band WiFi, a green light typically correlates to the 2.4 GHz band while a blue light indicates the 5 GHz band. Send and receive lights on an Arris modem indicate the status of the internet connection for uploading and downloading data.

Arris modems with WiFi capability have additional wireless indicator lights to convey the status of each wireless band.

Online Light

When the online light on an Arris modem is solid green, it signifies the modem has connected to the internet successfully. A blinking or solid red online light means the modem was unable to register an internet connection. This could require contacting your internet service provider for assistance. A solid green online light on an Arris modem means it has successfully connected to the internet service provider.

Some Arris modems have a link light that indicates data transfer status. A blinking link light shows data traffic flowing through the modem. A yellow link light points to a potential issue with the cable connection. Blinking send or receive lights on the Arris modem point to a disruption in the connectivity on that specific band. If all the Arris modem lights start blinking blue simultaneously, this likely means a grounding problem has been detected.

Phone Light

Certain Arris modem models include a phone light. When lit, this indicates the modem has a connection to telephone service. The phone light applies to modems that provide telephony capability. Blinking send and receive lights on an Arris modem typically signify connectivity issues with one or more bands of the internet connection.

All Lights Blinking

A key caution with Arris modems is if all the lights are simultaneously blinking blue. This pattern indicates a potential grounding issue was detected, which should be addressed before using the modem.

Power Light Troubleshooting

If the power light on your Arris modem is solid red, this typically means the modem is unable to fully power up. Try unplugging the power cord from the electrical outlet for 30 seconds and reconnecting it to reboot the modem. If the issue persists, you may need a firmware update or the modem may require replacement. Troubleshooting Arris modem lights involves checking for solid connections, rebooting the modem, and reviewing security settings.

A flashing green power light that continues beyond 5 minutes often indicates the modem is stuck during the boot up sequence. Unplug the power cord for 30 seconds before plugging it back in to force a cold reboot. If the Arris modem lights are unexpectedly out entirely, checking the power and coaxial cable connections is the first logical troubleshooting step.

Send/Receive Lights Blinking

Blinking send and receive lights on your Arris modem generally signify a connection problem on one of the internet bands. For dual-band modems, this often means the 2.4 GHz band is connected but not 5 GHz. Try rebooting the modem and double checking all cable connections. If blinking persists, log in to the modem to check the status of each band.

Arris modem lights remaining solid after rebooting and reconnecting cables often indicate the need for a firmware update. Technical bulletins on the Arris website provide useful troubleshooting advice for many common Arris modem light patterns.

Online Light Blinking/Solid Red

A blinking or solid red online light on an Arris modem means it was not able to successfully register an internet connection. Contact your internet service provider for assistance with establishing a connection. Be ready to provide your modem’s MAC address and serial number.

Slow Speeds/Connectivity Issues

For slow internet speeds or connectivity problems, first check that all coaxial and Ethernet cables are tightly plugged into the proper ports on the modem and wall jack. Also verify your WiFi network’s security mode and password if connecting wirelessly. Try rebooting the modem and router if the issues continue. Checking for firmware updates and resetting the modem to factory defaults can help resolve persistent problems.

No Lights At All

If your Arris modem has no lights showing, first verify the power cable is firmly connected to the electrical outlet and modem. Try connecting the power cable to another outlet in case the original one is faulty. Also check that the coaxial cable is securely attached to the modem and wall jack. As a last resort, attempt rebooting the modem and router. If the modem remains unresponsive, contact technical support.

Understanding the WiFi Lights

Many Arris modems have dedicated WiFi indicator lights separate from the main internet connectivity lights. These WiFi lights give information about the status of the wireless network being broadcast from the modem.

A solid WiFi light indicates the wireless network is up and running. A blinking WiFi light means data traffic is actively flowing over the wireless network. Arris modems have dedicated WiFi lights separate from the main internet connectivity lights to show wireless network status.

For dual-band WiFi models, the WiFi light colors typically correlate to 2.4 GHz and 5 GHz bands. For example, a solid green WiFi light could mean the 2.4 GHz network is available, while solid blue indicates the 5 GHz network is online.

Some Arris modems may use blinking WiFi light patterns to show if wireless clients are connected to that band. For instance, a slow blinking green WiFi light often signifies connected devices on the 2.4 GHz band.

If the WiFi light on your Arris modem is off, it usually means that wireless network is currently disabled. You can log into the modem to check or reenable the WiFi broadcast settings for that band.

Troubleshooting 101: First Steps for Modem Light Issues

When you first notice an issue with your internet connectivity, checking the lights on your Arris modem is a great place to start troubleshooting. There are a few basic first steps to try that can often resolve common modem light problems:

Unplug and reboot the modem

Referring to the Arris modem lights legend on the bottom of the device can provide a quick reminder on what each indicator represents. If you see abnormal modem light patterns, blinking lights, or no lights at all, try unplugging the power cord from both the electrical outlet and the modem itself. Wait at least 30 seconds before firmly plugging the power back in to restart your modem. This may clear any temporary glitches and allow the modem to reconnect properly. Just remember to be patient during the modem boot up process indicated by a flashing power light.

Check all cable connections

Make sure all your cable connections are secure on both ends. Check that coaxial cables are threaded tightly onto the modem and wall outlet ports. For wired connections, ensure ethernet cables are plugged snugly into the modem and computer. Loose connections can impair signal and cause blinking modem lights. Inspect cables closely for any damage too.

Review modem light legend

Refresh yourself on what each modem light signifies by checking the indicator legend typically printed on the device or in the user manual. Match up any problematic lights with the definitions to identify where the issue may lie. Knowing the light meanings is crucial for accurate troubleshooting.

Contact internet service provider if needed

If rebooting the modem and verifying connections does not resolve the problem, reach out to your internet service provider for assistance. Be ready to convey details about abnormal modem lights, connection types, and troubleshooting already attempted. Your provider can then help further diagnose the issue using the modem light indicators.
