To fix the “ERR_INTERNET_DISCONNECTED” problem, you must first figure out where it came from. This error message might show in the browser for several reasons.

The primary and common cause is the presence of antivirus software on your computer. Antivirus usually uses a Firewall to safeguard you when you’re on the internet. It can occasionally cause internet disconnection. Web browser cookies and caches can also prevent connection to the web.

It could result from a problem with your LAN (Local Area Network) or wireless connection settings. A change in LAN may affect your internet settings, causing your computer to disconnect from the internet.

  • Your internet is down due to network connectivity issues.
  • Network drivers that are out of date or incompatible.
  • Your antivirus software is blocking the connection.
  • The network settings on your computer are incorrect.

It could also be a faulty wire or a router that needs to be rebooted or replaced. If you are encountering the “ERR_INTERNET_DISCONNECTED,” then you are at the right place. Today, we will provide you with several troubleshooting methods that you can perform to get your internet back up and running again.

Troubleshooting Methods

There are multiple troubleshooting methods that you can perform to fix the “ERR_INTERNET_DISCONNECTED” internet error. But before you perform any of them, it is crucial to isolate the problem. Make sure not to skip the first troubleshooting method.

First Method – Make Sure You Have Internet Service

Check to see if the Internet connection in your location is up and running. Use a different device on your network to connect to the internet.  If the problem affects all of the devices in your network, then it could be a problem with the internet itself.

If the issue affects a single device, then it means your internet router is working fine, and your computer’s network settings cause the problem.

Rebooting your internet router may fix the problem. Hold down the power button on your internet router and wait 30 seconds for your router to turn off (steps may vary on the model of your router).

Now press the Power button again and wait for the internet router to finish booting. After your router has booted, see if the problem still exists. If the problem persists but only on a single device, you go ahead with our troubleshooting methods. However, if you are experiencing it on all devices, you should contact your Internet Service Provider to report the issue.

Second Method – Refresh Your Computer’s Connection to Your Network

One of the simplest remedies on our list for the “ERR INTERNET DISCONNECTED” message is to tell your computer to ignore your internet connection. This will allow you to re-establish your computer’s connection to the network connection and determine whether the error message was caused by a routing issue on the Wi-Fi network.

  1. Click on the Internet Icon on your system tray located on the bottom right corner of your desktop.
  2. You will see the list of Wi-Fi networks available in your location and the one that you are connected to.
  3. Right click on the Wi-Fi network that you are connected to and click on “Forget”.

Third Method – Clear Your Internet Browser’s Cache

If you’re using a web browser like Google Chrome, Mozilla Firefox, or Microsoft Edge, you should try deleting its cache files. The cache files stored in your browser will help the site load faster when you revisit a website. These cache files can become corrupted and cause your storage to fill up, causing some websites not to load or slowing down your computer. To clear your browsers, follow these steps.

Fifth Method – Disable Any VPN Service

You may get the “ERR_INTERNET_DISCONNECTED” internet error if you are using a VPN service. Most of the time, the VPN you are using connects you to the internet with an IP address from a different country. Try to disconnect your VPN from your computer to see if it fixes the problem.

If you are using a third-party VPN service provider, make sure to disable it to determine if it is the one causing the problem.

Sixth Method – Disable the Windows Firewall Temporarily

The Windows Defender Firewall is an essential tool that helps prevent any potential data breach.  However, it may mistakenly identify certain websites as malicious and block access in other cases. The err internet disconnected error happens as a result. To fix this problem, use the steps below to disable the Windows Defender Firewall temporarily:

  1. Hold down the “Windows” + “R” keys on your keyboard and type in “control firewall.cpl” in the run command line.

  1. Click on the “Turn Windows Defender Firewall On or Off” on the left pane.

Remember, before you perform any of these steps, make sure to contact your Internet Service Provider (ISP) first to avoid committing any of the steps that will only lead to nothing. Imagine going through the trouble of doing all these steps only to find out that your ISP is just doing some maintenance on your network.
