Windows – How to solve “your connection was interrupted err_network_changed” error

administrationinternet connectionnetworkingwindows 10wireless-networking

I have a problem connecting to my home network wirelessly, and so far I have tried almost everything. When connected, I get a yellow sign on the wi-fi icon, and an

err_network_changed

message in browser. I am using two laptops on the same network and one works fine, but the second one is is causing problems.
Here is some information about my machine and things that I have tried so far:

  • Laptop – Dell Inspiron N5100
  • Windows 10 Pro (Version 1803) OS

Tried:

  • Online search

  • Flushing DNS

  • Resetting router

  • Winsock reset

  • TCP/IP settings reset

  • Re-installing drivers

  • Searching for official Dell wireless drivers, but
    can't find them for Windows 10. I've tried Windows 7 but no luck.

  • Disabling Ethernet

  • Disabling/enabling wireless connection

  • Using Google's DNS

  • Changing IP to static.

  • Windows full reset

I doubt it is a hardware problem, because I have been connected to home network and it all worked fine but suddenly this happened. Note that I have no problem connecting to any other network, but for some reason can't connect to the one at home. I've also looked at wireless statistics for my router and I see that package receiving is very low.

Here is some additional info from IP Configuration: enter image description here

I am using the TP-Link WR740N router.
Any suggestion or link to a solution is very helpful, thank you for your time.

I think your WiFi connection is unstable, but there isn't enough information in your question to prove that theory. When you get an 'error: network changed', it is a sign that Windows has registered that the network interface has gone up or down (possibly briefly). Here are a couple things you can try:

  • What is the signal strength reported in windows? Do conditions improve when you move closer to your router?
  • Does your issue coincide with interference (i.e. use of microwave oven)?
  • Are you using wireless repeaters? I find these to be incredibly unreliable.
  • If you ping your router indefinitely (e.g. ping 192.168.1.1 -t), do you see a lot of packet loss? Are the packet counts on your router and computer in close agreement? Does your router list/count packet errors, and is this number at least an order of magnitude lower than the successful packet count?
