Hi,

Thanks for posting here.

Before we go further, may I confirm with you what's the OS version of your Win 10 client?

Meanwhile I would like to confirm whether you can access to Office 365 or Outlook?

Best Regards,
Sunny

sorry for the late reply, Windows 10 version 2004. And another problem is it's too slow when access to Internet with browser after connecting to wifi.

Hello Andre0,

Generally the Internet icon shows connectivity when the system is able to resolve and ping *.Microsoft.com. If you can surf the Internet but you see an icon with a yellow triangle, it's likely that there is no access to Microsoft (thus you cannot access the MS store).

If this ONLY happens when you are on WiFi, then the likely cause is that the WiFi router or WiFi zone has some sort of site blocking enabled OR you have a misconfigured DNS setting on the WiFi adapter.

If this happens regarless of whether you are WiFi or on Cable, then the issue might be misconfigured DNS on your router/adapter, DNS blocking service (such as OpenDNS) disallowing acces to MS or software installed on your PC that block access to MS.

Hi,

Thanks for your reply.

Based on my research "NCSI taskbar icon may report "no internet" on Windows 10 2004 devices that DO have internet access" is a known issue, for more information, please kindly refer to the following link:

https://social.technet.microsoft.com/Forums/en-US/4c8654be-d3da-4611-a649-110ca5a7c70a/ncsi-taskbar-icon-may-report-quotno-internetquot-on-windows-10-2004-devices-that-do-have?forum=win10itpronetworking

You can assign the IP address manually to the impacted client as a workaround, then everything works again. You can even switch back to DHCP after that.

Please refer to the following detailed steps:

Click "Start" button and insert cmd.exe, select Run as administrator. Then please insert the following command in cmd window:
ipconfig /all

Locate the IPv4 address of Wi-Fi adapter and remember the IP address, Subnet Mask, and Default Gateway.

Click Start button and insert "ncpa.cpl", press Enter to access to Network Connections. Right click the Wi-Fi adapter and select properties. And then please select TCP/IPv4 and click Properties.

Please select "Use the following IP address" and inset the IP address, Subnet Mask, Default Gateway manually and click OK to apply the changes.

And then, please go back to the TCP/IPv4 properties and select "Obtain an IP address automatically" and click "OK" to apply the change.


Hope my answer will help you.

---Please Accept as answer if the reply is helpful---

Best Regards,
Sunny

Does not work. We have manual IP's (no DHCP) and use a Proxy Server. Windows always says 'No Internet', but we are connected! When will this issue got resolved?

This was the cause so thank you for identifying that. However there is a much simpler fix if you are using DHCP:

  1. Open a command prompt as administrator

  2. Type ipconfig /release

  3. Type ipconfig /renew

I had the exact problem as the OP. My computer is connected by ethernet. My ISP went down over night. In the morning I could use the Web, ping and resolve DNS. Outlook and other apps would not connect, and the tray icon showed showed as no internet. I'm sure rebooting would have worked as well (as it does for most problems).

For those that say this didn't work, it would be because you have a different problem with the same symptoms.

I'm sorry but is this the official Microsoft response to a bug in the NLA Service? Use Google's servers?

What is the reference for this bug and where can we track its progress towards being fixed? This bug and the fix have been around for at least eight years but based on complaints being raised in support forums for apps that rely on it (Microsoft Store, Spotify etc) a recent Windows Update made it ever so much more unreliable.

Please answer the following questions:

Is this a home PC or a corporate issued PC?
Does the problem occur at your home only or when you take your laptop to other places as well?
Are there surfing restrictions on your laptop by a corporate entity or IT manager?

If you are a small company and it is OK with you to setup the proxy using IP instead of FQDN I think it can work.

Worked for me and doesn't involve changing "ping" servers. Thanks!

Believe or not
1, Unplug the LAN cable which is connecting switch from the Modem. Wait for 1s.
2, Unplug the LAN cable which is connecting switch from the PC. Wait for 1s.
3, Plug-in the LAN cable from switch to PC. Wait for 1s.
4, Plug-in the LAN cable from switch to router. Wait for 1s.
5, Solved until next restart :-)

Luckily I fix the issue by allowing "Core Networking Diagnostic" through firewall:
control panel > Windows Defender Firewall > Allow an app or feature through Windows Defender Firewall
then scroll down to "Core Networking Diagnostics" entry and check the 3 checkboxes under Name/Private/Public.
