Getting errors with new Windows system can be annoying! Now, the question is how to solve them effectively without high costs or downtime. One of the most common error messages people have been seeing is ERR_NETWORK_CHANGED error occurring with Google Chrome.
There are many solutions online, but we have collected them into one single guide with easy to follow simple steps to restore the network connectivity after that annoying error message. Please feel free to comment and suggest any more effective solutions.
1. Fix: “Err Network Changed”: Reboot your modem and check network settings
Now, this may sound like an obvious thing, but simple recycling of the modem can solve many of the problems. Sometimes this may be because of the time needed for the modem to start up again, so that the user herself calms down and figures out that there was not a problem after all. But, sometimes it may be that network settings indeed are scrambled and a simple recycle of power does solve the issue.
Same goes with network settings. It might be, that your manual settings required for the network to function are timed out, and simply by restoring automatic mode might solve the issue. This can be by ensuring that “Automatically Detect Settings” and DHCP are turned on. This way, your Windows PC will do its best to detect the network environment and to configure any settings automatically.
2. Refresh DNS settings
Name servers form a network of nodes in which each node maintains a cache of entires. This makes the Internet work like it does, to have your web sites to appear in a an instant. However, as things change in the network, it may take time for the change to get propagated everywhere. So, this can cause errors too! One way to solve connectivity issues is to reload, or flush, the name server cache.
This will make your computer to forget any former responses it got to queries about network locations. Next time it needs something, it will go and ask others. That can solve many temporary name server issues. To reset the name cache, just write, in console window “ipconfig /flushdns”.
3. Use custom DNS, like ADGuard or Google
Many network related connectivity issues originate also from the broken or invalid name server in use. One easy and common way to check if that is the problem is to set up the Windows to use other name servers. There are many open and public name servers available, eg. from Google, but also from Advertisement blocker companies like ADBlock. These services and act as a resolution to some censored sites too, as it is up to the name server if they deliver a response or not.
From the network connection settings page in Windows, you can define the name servers to be used. The layout and location of the settings panel changes from Windows version to version, so please refer to your respective documentation to find out the exact location of the setting.
Google name servers (Free!)
AdGuard name servers (Free!)
The former name servers will also provide additional security, as they refuse to deliver responses to any malware or advertisement sites.
4. Empty Browser Cache
Small things like clearing up the browser cache can also sometimes solve annoying network connectivity issues. This can happen because the browser might have invalid network addresses in its internal cache or preferences.
Clearing the browser cache varies according to the browser, so please refer to your browser documentation on how to preform that maneuver.
While clearing the cache may not be such a straightforward task in some browser versions or models, one simple way to ensure that browser cache is not to blame is to try out using different browser! That is in effect similar, if not the same, thing than being successful in clearing the cache and any stored preferences or settings.
5. Reinstall or reconfigure your VPN software
While VPN software can give a lot of good for your security it can also cause connectivity issues like this one. Reconnecting, reinstalling or reconfiguring your VPN connection software can potentially solve connectivity issues like this. However, please be careful when tampering with your VPN settings, as removing that could also cause loss off connection altogether or loss of added level of security.
Again, please be aware that some VPN clients come up as trojans, pretending that they provide network encrypted tunnel, but in fact just deploy their malicious infrastructure instead.
