Windows 10 says I have no internet connection, but I have.

I am running on Windows 10 Enterprise, Version 2004, OS Build 19041.264.

I recently changed to the Windows Insider Program and updated Windows. In the taskbar, the Wi-Fi icon shows No Internet Access, but I have a stable internet connection wirelessly (Ex: I can browse the internet, ping IP Addresses, etc.). Another problem is when I try to open Cortana it also says that I have no internet connection (By the way, I can also open Microsoft's website).

As I know Windows checks internet connectivity with this URL: http://msftconnecttest.com/connecttest.txt. But this gives Error 404, File Not Found. Maybe it is because of this?

If you know the problem or an answer, please help. Thanks!

Hello, use Registry Editor, go to: 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet

and modify: EnableActiveProbing

then change "Value data" from "0" to "1"

and restart your computer

The proper one is

"HKLM:\SOFTWARE\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator\” -Name UseGlobalDNS -PropertyType DWORD -Value 1 -Force

But the more appropriate way to do this is not through registry directly, but through group policy config:

    You have it right.

    EnableActiveProbing DWORD 1 = active probing ON

    And you should always have active probing ON.

    Disabling NCSI's ability to detect internet connectivity will break apps like Office suite / Teams / Skype / and various third-party apps that call our NCSI API to determine state of connectivity.  

    When NCSI returns false positive "No Internet" status (when connectivity truly is intact) it's because it can't get an answer to successful probe.   These apps trust the status NCSI returns and will assume it's correct and thus err back to the user that it can't do <network operation>.

    When you have an NCSI problem scenario it is necessary to troubleshoot why the active probe to http://www.msftconnecttest.com/connecttest.txt fails, or DNS query to dns.msftncsi.com does not resolve.

    This most commonly proxy failures (can't detect proxy when there is one / proxy not forwarding request properly), or basic network routing issues, or DNS resolution issues.

    Your real problem is failure to resolve the DNS query.  Overriding it with the hosts file may work but if the server address were to change in the future you'd be stuck again.

    To fix this properly run a packet capture and determine why the DNS query is timing out.   So long as your DNS server returns the proper response this should work.
