Why Your Arris Modem Keeps Disconnecting And How To Fix It

If your Arris modem keeps disconnecting you are in the right place. This issue can be pretty annoying when you are trying to work from home, stream a favorite show, or in the middle of an intense online gaming session.

In this article, we will explore the possible reasons for the recurring disconnections and provide some practical solutions to restore your internet connection.

But first, let’s see why this is happening.

Why Does Your Arris Modem Keep Disconnecting?

Before we list the solutions, it is important to understand why your Arris modem keeps disconnecting. The frequent disconnection can be caused by several different factors.

Poor Signal Quality

Is the Wi-Fi signal weak

If you haven’t placed your modem in the optimal position, it is possible that it is not getting a strong enough signal. Physical obstacles like walls and furniture or interference from other electronic devices can also affect signal quality.


All electronic devices, including your Arris modem, are prone to overheating. If your modem runs for long hours without proper ventilation, it could overheat and disconnect frequently to protect itself.

Cable Connection Issues

You need to make sure that all the cables coming to the modem and out of it have to be firmly and properly connected. Loose or damaged cables can cause connectivity issues.

ISP Issues

Sometimes, the problem can be caused by your Internet Service Provider (ISP). Network congestion or downtime at your ISP can make your modem disconnect regularly.

Outdated Firmware

If your modem firmware is outdated, it could cause instability in your connection, leading to frequent disconnections.

How To Fix The Issue Of Arris Modem Disconnecting

Knowing what is causing the Arris modem disconnections is half the battle. Now you can implement the following fixes.

Restart The Modem

Restarting, or power cycling, your ARRIS modem can often resolve temporary connectivity issues or glitches. You can easily do it in a few simple steps:

  • Step 1 – Unplug your Arris modem
  • Step 2 – Wait for a while (1-3 minutes)
  • Step 3 – Plug your modem back in
  • Step 4 – Wait for the modem to boot up and the Arris modem LED lights to stabilize.
  • Step 5 – Check your internet connection

If you are still experiencing frequent disconnections, try the following solution.

Optimize Your Modem Placement

The placement of your modem can have a great effect on the strength and stability of your connection.

Make sure to place your modem in an open, central location, away from physical obstructions like walls and furniture. Other electronic devices can also cause interference, so keep items like microwaves, cordless phones, and baby monitors at a safe distance.

Try moving your modem to a different location to see if the disconnection issue improves. Once you find a location with a stable connection, place the modem there permanently.

It can take a bit of trial and error, but the result will be worth it.

Prevent Overheating

Is Arris modem overheating

Touch your modem to see if it’s unusually hot. If it is, it may be overheating and causing disconnection.

Make sure that the modem is in a well-ventilated area and not enclosed in a cabinet or stuck in a tight corner.

If you think the modem is already overheating, disconnect it, let it cool down for a bit, then plug it back in. In case the disconnections continue, it is possible that overheating is not the issue, but an obsolete firmware.

Update Your Firmware

If your firmware is outdated, it could cause instability in your connection, leading to frequent disconnections. Login to your Arris modem using a web browser (you can find the exact steps in our Arris modem login guide), and check if there are any available firmware updates.

Follow the instructions to upgrade the firmware but remember to back up your settings before you do, just in case anything goes wrong.

Contact Your ISP

If you have tried the above solutions and your modem is still disconnecting frequently, your ISP is probably the reason. They sometimes experience network congestion or have to perform routine maintenance. Both these situations can make your Arris modem disconnect frequently.

Check your ISP’s network status page or contact their support to confirm if they’re experiencing any issues. They can give you an estimated timeline for when they will fix the issue.
