How to solve "your connection was interrupted err_network_changed" error?

Question

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:

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

Solution

Problem was with my wireless configuration in router, my channel was set to "auto", therefore router was assigning wireless channel automatically and thus causing the interference with another near by access point, i was able to solve it by changing the option. See how to change wifi channel
