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:
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.
