ARRIS Modem Lights On But No Internet: A Quick-Fix Guide

Is there anything more frustrating than your internet connection suddenly dropping out? Especially when your modem seems to be working fine. If you own an ARRIS modem and you’ve noticed that all the lights are on, but there’s still no internet, you’re not alone.

In this article, we are going to explore this problem in detail, check the possible causes, and show you how you can fix it.

Why Are The ARRIS Modem Lights On But No Internet Connection?

Your ARRIS modem has one or more indicator lights depending on the model. These lights show us the current status of the network and different modem functions.

When these lights are on, it typically means that:

  • the modem is receiving power
  • it is connected to the network
  • the internet connection is working properly

However, if there’s no internet, it’s possible that there’s an issue with the ISP service or the device itself.

Possible Reasons For ARRIS Modem Lights Being On But No Internet

Internet Service Provider (ISP) Outage

If the lights on your Arris modem are on but there is no internet, one possibility is that your ISP is experiencing an outage. This could happen because of scheduled maintenance, a technical issue, or a network problem in your area.

Hardware Or Firmware Issues

Another potential cause could be hardware or firmware issues with your ARRIS modem. For example, a firmware update might have gone wrong, or there may be physical damage to the modem preventing it from functioning properly.

Configuration Errors

Lastly, the problem could be caused by some configuration errors. This might include incorrect settings on your modem or an issue with other devices on your network.

How To Fix Your ARRIS Modem When The Lights Are On But There’s No Internet

Now that you know the possible reasons for this issue let’s see what you can do about that. The following solutions can help you troubleshoot and possibly fix this issue.

Check For ISP Outages

The first thing to do right now is to check whether the issue is with your Internet Service Provider (ISP). Your ISP might be experiencing an outage due to scheduled maintenance, technical glitches, or regional network problems.

Xfinity outages reported

To do this, visit your ISP’s official website or check their app from a device that has internet access (like your smartphone using mobile data). Most ISPs have a dedicated section for service outages.

For example:

Another way to check this is to contact their customer service line for real-time updates.

And finally, you can check whether other users are experiencing issues with their ISP on sites like, official forums, or official social network accounts.

 If your ISP is indeed experiencing an outage, all you can do is wait for them to resolve it.

Restart Your Modem

If there is no ISP outage, the next thing to try is a simple modem restart. This is also known as power cycling, and it is an effective way to clear out minor glitches and reset your modem’s connections.

Unplug your modem from the power source. Leave it disconnected for about a minute, then plug it back in. Give the modem a few minutes to reboot completely, and then try reconnecting your devices.

Update Your Modem Firmware

Sometimes, a firmware update may have been incorrectly installed or your modem may be operating on outdated firmware. Both scenarios can lead to internet issues.

To check the firmware version and update it if necessary use the SURFboard Manager app. You can follow the instructions presented in this guide.

Factory Reset Your Modem

If the issue is still present, the next step is to factory reset your modem. This process will return your modem to its original factory settings and is useful for clearing any configuration issues that might be causing the problem.

To factory reset your ARRIS modem, find the small reset button on the back of your modem. Using a small, thin object like a paperclip, press and hold the button for about 10 seconds or until the LED lights on the front panel flash, then release. The modem will reboot and reset, which can take a few minutes.

Please note, after a reset, you need to set up your modem again. This means entering your ISP login details and reconfiguring any custom settings you had before.

Contact Your ISP Or ARRIS Support

If they determine that the issue is with your ARRIS modem, your next step is to contact ARRIS Support.
