So, it restricts the user’s access to the network. Restarting the computer doesn’t tend to work in this case. It is a mystery to solve but I would definitely assist you in getting rid of this.
To fix this error, it is important to recognize the culprit. There are a number of reasons causing this error message to appear on the browser.
The first and the most known reason causing it is the antivirus software program installed on your PC. Antivirus tends to protect you over the internet using Firewall strategy which can also result in disconnection to the internet at various occasions.
Your Local Are Network (LAN) or Wireless Connection can also be the reason of its occurrence. Sometimes, a change in LAN can affect the settings and disconnect your PC.
Browser cookies and caches can also stop the internet access.
Reconnect to your wireless or wired network (do a power cycle, power the router/switch off), then turn it back on & then re-connect your device (iPad/iPhone/Computer or any other device)
In General; your system is not able to access the Internet. So the first thing to ensure is the connectivity (whether it is wireless or wired) check and make sure that you are able to connect to the router or switch from your other devices; in case of wireless try connecting a phone or a smart device to this router wirelessly and see if internet works; in case of wired another computer over the ethernet to the router. This will confirm if the router is getting internet from the provider; if it is then we continue with the steps below but if it is not; then we need to troubleshoot this with the ISP or the Internet Provider.
Solutions to Fix Error ERR_INTERNET_DISCONNECTED
Based on the reasons I mentioned above, there are numerous solutions to resolve this problem. You should give a try to the following methods and check if a particular method works for you or not.
Method 1: Fix Local Area Network Settings
One of the reasons behind the error ERR_INTERNET_DISCONNECTED is an automatic change in Local Area Network settings inside your PC. So, by modifying those settings, you can bring your internet back to work.
Go to Control Panel by pressing Win + X on the keyboard inside Windows 10 and selecting Control panel from the list. In other versions of Windows, you can open it from the start menu. Inside the control panel, click on Internet Options. If you can’t find it, then switch the view to small icons and you would see it.
Inside Internet Options window, navigate to the Connections tab located at the top and press on the LAN settings
When you are inside LAN Settings, uncheck every option and click on OK. It would definitely work for you. If, for some reasons, it doesn’t do the job, then move to the next solution.
Method 2: Clearing Browsing Data
Cookies and caches can terminate your network connection. So, clearing them will resolve the issue related to your internet connection. Follow the steps to clear browsing data on the famous browsers.
Clear Browsing Data on Firefox:
You can clear the browsing data on your Firefox browser by pressing Ctrl + Shift + Del shortcut key on the keyboard. It will open a new window with default options. Just click on Clear Now button and restart your Firefox browser to browse the web.

Method 3: Reinstalling Antivirus
Antivirus and Firewall or other security softwares can also restrict access to the internet. The first step here is to uninstall antivirus from Control Panel -> Programs & Feature -> Uninstall a Program. After it has been uninstalled; check if you can now access the Internet; if YES then your AntiVirus software was the culprit (you now have the choice to) continue using the same by reinstalling it and allowing it to allow internet; or use a free one like AVG which does the same job in my opinion as any other anti-virus software.
Method 4: Delete WLAN Profiles (Wireless Profiles)
Hold the Windows Key and Press X and choose Command Prompt (Run as Administrator) or Click Start -> Type cmd -> Right click cmd and choose run as administrator.
Once in the command prompt, type netsh wlan show profiles
then, type the following command and remove all wifi profiles.
netsh wlan delete profile name=”[PROFILE NAME]”
Do this for all the wifi profiles, and then reconnect to only your wifi.
Make sure you do not include the “quotes” when removing Wi-Fi name.
