Still not fix ‘no internet’ connection bug in Windows 10 2004 (OS Build 19041.546)

Question

I ever posted this issue on MS TechNet and someone told me that it’s a bug on version 2004 from Microsoft. Then nothing can do.

So I tried this.
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet”
Modify “EnableActiveProbing” and change the value from ‘0’ to ‘1’.

Result: Not help. It only works successfully for every several computer start.

Recently, I find this bug is fixed from below info.

• Addresses an issue that might prevent applications from opening or cause other errors when applications use Windows APIs to check for internet connectivity and the network icon incorrectly displays “No internet access” in the notification area. This issue occurs if you use a group policy or local network configuration to disable active probing for the Network Connectivity Status Indicator (NCSI). This also occurs if active probing fails to use a proxy and passive probes fail to detect internet connectivity.

After upgrade my PC to OS Build 19041.56. The issue is not solved. It only works normal for every several computer start.
If 'no internet' issue happens, I can't syn email normally on Outlook / Open onedrive files from Excel / Spotify app failed.

Please help.

p.s. How can I get email notification if someone answer from this new forum?

Answer 1

Hi ,

Thanks for your updating. Have you checked HKLM\Software\Policies\Microsoft\Windows\NetworkConnectivityStatusIndicator to see if there any registry keys?

Find a solution. If I connected Surfshark VPN and access Internet, then disconnect VPN. It will return to normal. 'No internet' issue will be disappeared.

Good to hear that you have solved this issue by yourself. In addition, thanks for sharing your solution in the forum as it would be helpful to anyone who encounters similar issues.

In addition ,if there is no specific event/error about the problem, it is hard for us to analyze root cause from forum support level . In such case, we need to trace network monitor to find any clues. Unfortunately, analysis of network traffic is beyond our forum support level. If the issue is urgent and you want to find the root cause, I would suggest you open a case with Microsoft where more in-depth investigation can be done so that you would get a more satisfying explanation and solution to this issue.

Answer 2

I had temporary success when starting the diagnostic wizzard on the network adapter. It couldn't fix any issues but starting the diagnose wizzard triggered something which lead my network adapter to display Internet Conectivity. At least till the next reboot.

After the next reboot, everything was like before: No Internet.

Looks like the diagose wizzard triggers NLA or something like that....

On my system this bug began with Windows 10 Version 21H1. All the Registry and GP hacks above do not resolve the issue. I have deleted the driver for my primary network adapter and restarted my PC. This fixes the issue temporarily but it returns the next day. Now the Globe icon is an ever-present and unwanted guest in the Notification Area (System Tray) even though the Internet connection works fine. This is a major bug in Windows 10 and needs toe e fixed in the very next monthly update.

Answer 4

We are seeing the issue with multiple users working from home. Not at work (maybe proxy server caches)?
I see lookups on DNS probe - TTL is 30 seconds, so maybe the issue is that it times out ? Too slow response, and this dns.google is better, as it has a much longer lifetime (600+ seconds).
Mirosoft could use a much longer TTL, if their network stack is sensible (i.e. deletes cached DNS entries when network state changes, to allow for split-DNS (same name internal/external gives different replies).)

Maybe the www.msftconnecttest.com is too slow at times ? I am really considering using cloudflare fronted company site for the connecttest.

Answer 5

We experienced this issue for any user on 20H2 connecting via VPN.
Users on 1809 worked without any issue.
The fix for us was to enable the below. Since enabling no further reports of the issue.
This may or may not be of use to others but resolved it for us.
