If that isn’t the case, here are some potential causes responsible for your router restarts:

1. Fault in cables – A loss of signal or power temporarily might make your modem restart every time this happens.

2. ISP restart – An interaction or request for remote restart from your ISP, will restart your modem.

How To Fix Arris Modem Keeps Rebooting Issue?

First, it is good to notice whether your Arris modem has been an object of any kind of damage.

A potential water or drop damage can lead up to those sudden restarts users have said, but if you figured that’s not the case, then here are some proven fixes for this issue.

Fix #1 Refresh the Power Of Your Arris Modem

The first fix you will be applying is a power refresh or also called a power cycle.

The power cycle will refresh the electricity from your device, hopefully preventing it from restarting itself any further.

Here are the steps to the power cycle:

1. Turn off your device and unplug its power adapter.
2. Wait for several minutes.
3. Plug the power adapter into a wall outlet.
4. Turn on your modem.

Once you’re ready you can test and if your modem keeps restarting, please move on to our next method.

Fix #2 Remove Power Strip/Divider

In case you have your modem connected to a power strip or divider, it is possible for the modem to restart if the strip device is faulty.

These devices are well-known to develop issues impacting your device’s functionality over time, so make sure to plug your modem into a different outlet if possible.

The wall outlet can provide the best possible power supply for your Arris modem and there is no danger or whatsoever of your device going faulty.

Fix #3 Inspect Power Adapter

Another reason for your modem to randomly restart is a faulty power adapter.

If the power adapter has been disrupted somewhere, it can constantly cut out the electricity to your modem and then supply it back, causing your device to restart.

It is best to inspect the power adapter with another device to ensure its functionality or buy a new one for your modem.

Pro Tip: While you’re still here, we recommend unplugging ALL cables connected to your router and reconnecting everything from scratch.

Fix #4 Update Your Modem

If your Arris modem keeps restarting it could be because of a fault in the software of the device. While your modem’s uptime, you must ensure that the device is updated.

Sometimes even a pending update that has not been accepted can make your device occasionally restart.

To update your modem, you must head to your manufacturer’s website where the process will be described in detail but we will include it here also.

Step 1: Go to the download page on your manufacturer’s website and head to the downloads tab.

Step 2: Locate the newest firmware version available for your modem and compare them.

Step 3: Download the latest version by pressing the apply button.

Step 4: Wait for your modem to restart and the firmware will be updated.

Note: in case you’re wondering how to compare versions, in your modem’s registration, the firmware and its version will be included in the options tab.

Fix #5 Perform a Factory Reset

If the Arris modem keeps rebooting after you update its software, then there might be a severe glitch.

The factory reset is a drastic measure, but really effective and this is exactly what we’re about to describe.

Note: Be informed that ALL settings and configurations (including your WiFi passwords) will be permanently gone after the reset. We recommend creating a backup.

To perform a factory reset on your Arris modem, follow the steps below:

1. Locate the reset button on the back of the modem.
2. Hold the reset button for at least 15 seconds.
3. Wait for the reset to complete.

The reset button is located in a small pinhole and to reach inside you will need a small and sharp object (paperclip, needle, or pencil).

In case you’re having trouble with the reset button, there is another way to reset your Arris router.
