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:

    Thanks Tom for the kind comments.

    I have got a solution adding a key from PS

    New-ItemProperty -Path “HKLM:\SOFTWARE\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator\” -Name UseGlobalDNS -PropertyType DWORD -Value 1 -Force

    Glad to hear it worked!

    I did not say that NCSI has *never* had a bug.

    But of course you are testing on a system that is fully up-to-date with our monthly updates.....correct?

    In your URL list there's 2 distinct NCSI bugs.   See (*) and (**)

    - You have three separate URLs for KB4554364 which fixes bug (*).  This has been public for some time, and should no longer be an issue if you keep your machine current with our monthly updates.

    • You have two URL's that point to (**) which I have mentioned in earlier comments it is actively being investigated.
    • You have two URLs that have nothing to do with NCSI

       - How to install CABs

       - Wifi connection issues troubleshooting page is not a bug, nor does it necessarily have anything to do with NCSI.

    "!!! in dutch: information about DISABLINGactive probe (official Microsoft documentation)

    https://docs.microsoft.com/nl-nl/windows/privacy/manage-connections-from-windows-operating-system-components-to-microsoft-services#bkmk-ncsi"

    I've spoken about our GPO that allows for active probe disable earlier in this thread, but I'll repeat it here:

    A long time ago (Win7) we introduced this GPO because some big public sector customers demanded it.  This was back in the day when Windows didn't send out a lot of unsolicited packets to the internet without prior admin configuration, and so the behavior was not desired by high-security environments.  Today this unsolicited outbound packet behavior has been normalized considerably with the development of all kinds of Windows components that do this...AOVPN and DirectAccess are big ones and must do this to "manage out" client machines.   

    Although we added this GPO, we certainly put the buyer beware verbiage very clearly in it:

    "This may reduce the ability of NCSI, and of other components that use NCSI, to determine Internet access."
