Usually, the broadband users encounter a lot of errors including the network errors. Generally, the network changed error occurs while using Chrome. I also encounter this error while using YouTube, Google Drive or Google Search and that’s why I am sharing here a handful of useful methods to resolve the “Err_Network_Changed” error. You can also share your experiences in the comments. But first, let me explain which techniques I follow whenever I face this error.
Method #1: Browser Troubleshooting (Most Working Solution)
Sometimes the problem is not with your network system. It is your browser that is creating a problem and not moving forward. So you should perform some troubleshooting tasks with the browser. Usually, the majority of users prefer Google Chrome. So, I am writing here about Google Chrome troubleshooting.
A) You need to remove browsing data by using the following steps:
On the top right corner of Google Chrome, there are three vertical dots. It is the option for “customize and control.” You should select it.
Now choose “More Tools” from the drop-down menu and then “Clear browsing data” from here.
Now a window with some checkboxes appears on the screen. Check all the boxes to remove its cookies and saved passwords, cache images and the plugin data, etc. Now select the option “Clear browsing data” at the bottom. It will take a few seconds, and your chrome will be error free.
B) You also need to remove all of the extensions you have currently installed because it may also be a cause for this error.
Go to the “Customize and control” option at the top right corner of Google Chrome (three vertical dots icon).
Now select “More tools” and then “Extensions” option from the menu.
Here, you will see all of the Google Extensions you have installed currently. You need to uncheck the boxes and click the delete icon with every extension to remove all of them.
Method #2: Flushing DNS
You need to go to the Start and type “command prompt” in the search function. Once it appears, just right click to see the option “Run as Administrator.” Click this option.
Now the command prompt appears on the screen. Type here “ipconfig /flushdns” command and press Enter.
Method #3: Reset TCP/IP by Using Command Prompt
If the above-discussed methods are not useful in your case, just try to reset TCP/IP by using Command Prompt Administrator again.
This time you will type the command “netsh int ip reset” and press Enter.
Now you need to restart your computer to make the changes effective.
Method #4: Add DNS Address Manually
If you are still facing the same error, just try to assign a DNS address to resolve this issue.
Go to Control Panel and open “Network and Internet.”
Now you will see “Networking and Sharing Center” category here. Just open it.
From the left pane, you need to select “Change adapter settings.”
Here, you will see your network. You need to right-click on it and select “Properties” from the list.
Now you need to select “Internet Protocol Version 4 (TCP/IPv4” from the list and select “Properties” tab given below.
Here, check “Use the following DNS server addresses” option and type “22.214.171.124” in Preferred DNS Server and “126.96.36.199” in Alternative DNS Server. Now click “OK” to save the changes.
I am sure this technique can get you rid of this annoying error.
Method #5: Check Proxy Server Settings
You should check the proxy server settings by following the steps below.
Open Google Chrome. Click on the “customize and control” option on the right top corner (three vertical dots icon).
Now select “Settings” option from the drop-down menu.
On the Settings page, keep scrolling until you reach the bottom of the page. You will see here “Show Advanced Settings” option. Select it.
You see a tab “Change Proxy Settings” under “Network” category. You should select this option to go ahead.
Now internet properties page opens up. Here, you should select “LAN Settings” as shown in the image below.
Here, you will see “Use a proxy server for your LAN” option with a checkbox. You need to uncheck it and click “OK” to apply the changes.
Method #6: Update Windows Drivers
Sometimes this error occurs because you did not update your Windows regularly. So, update Windows drivers, and it will work smoothly. Perform the following steps to do so.
Open “Control Panel” from the Start menu.
Now click the option “System and Security” that lies at the top of the categories.
Look for the option “Windows Update” and click as you get it.
Here, you will see the option “Check for updates.” Select this option to install updates for drivers.
Method #7: Router Power Cycling
The first thing you need to do is to power cycle the router. Just switch it off. Plug out all the cables from it. Wait for at least five minutes. Now plug in the cables and switch it on to see whether it works.
Method #8: LAN Settings
If the error is not resolved, you should change the LAN Settings.
Just click “Start” menu to open Control Panel.
Now click “Network and Internet” category.
You will see Internet Options. Just click on it, and you will see “Internet Properties” box.
Here, internet properties, you should select “Connections” tab as shown in the image. You will see “LAN Settings” tab at the bottom. You should click on this tab.
Now uncheck the option “Automatically detect settings” that appears in LAN Settings window. Click “OK” at the bottom.
That’s it. Now try again to access the internet.
