  1. Restart Your Router  

If you are facing a connection interruption error then we need to reset the router to fix it. A router connects our device to the modem and the internet and additionally changes our DNS server settings too. Unplug the router and wait for 30 seconds to restart. It will reset all settings in the router and if it’s the root of all problems, resetting DNS will automatically fix it. Once you reset your router, connect it with your device(PC or Laptop) and try to access the internet. If the connection was interrupted error still persists, then try other methods.

Restarting your router can reset some settings but it cannot change the DNS. We need to flush the DNS in order to reset the IP address. Flushing DNS will remove the old IP address and allow users to assign a new one. Here is how to flush DNS,

  • Go to windows menu and find command prompt, then open it with “Run as Administrator”

ERR_NETWORK_CHANGED

  • Now type “ipconfig/flushdns” and hit enter

ERR_NETWORK_CHANGED

Once you flush the DNS, you can change the IP address.

Now we need to change/reset the IP address in order to acquire a new one.

(Continue from above)  

  • Type ipconfig/renew and hit enter(it will release the old IP)

ERR_NETWORK_CHANGED

Now close the command prompt and open it again(with admin) and type


ipconfig /flushdns

nbtstat –r

netsh int ip reset

netsh winsock reset

Proxy works like a firewall between a browser and the internet. It works as a go-between and filters out connections and prevents websites to open. That’s why we need to change the proxy settings and disable them as well. Here is how to change proxy settings in windows,

  • Open the control panel and find internet option, select connection then open LAN settings

ERR_NETWORK_CHANGED

  • In LAN settings, look for the proxy server option, make sure to uncheck the box that says, “use a proxy server for your LAN”
