Since the network works and the issue is the status-detection layer, focus on NCSI and network profile detection rather than the adapter itself.
- Verify what Windows currently thinks the connection state is.
Run PowerShell:
Expected result for normal internet detection isGet-NetConnectionProfileIPv4Connectivity : InternetorIPv6Connectivity : Internet. If the profile is wrong here, the problem is in Windows network status detection, not basic connectivity. - Check whether NCSI active probing is enabled.
Open Registry Editor and review:
Confirm:HKLM\SYSTEM\CurrentControlSet\Services\NlaSvc\Parameters\Internet-
EnableActiveProbing=1
-
ActiveWebProbeHost=www.msftconnecttest.com -
ActiveWebProbePath=connecttest.txt -
ActiveWebProbeContent=Microsoft Connect Test -
ActiveDnsProbeHost=dns.msftncsi.com -
ActiveDnsProbeContent=131.107.255.255
-
- Do not disable active probing. NCSI uses active probes to determine internet connectivity. If probing is disabled, Windows can report no internet even when browsing still works.
- Check the NCSI operational log.
Open Event Viewer and go to:
This is the primary log location for NCSI probe and status events.Applications and Services Logs\Microsoft\Windows\NCSI\Operational - Confirm the probe endpoint behavior.
NCSI uses an HTTP query to:
http://www.msftconnecttest.com/connecttest.txtThe expected result isHTTP 200 OKwith contentMicrosoft Connect Test. - If the machine is domain-joined, also verify the applied network profile.
Get-NetConnectionProfileshould show the expected category, such asDomainAuthenticatedon a correctly detected domain network. On Windows 11, domain profile detection is handled by the Network List Manager rather than NLA. - If this started across multiple Canary builds and all services, drivers, and network reset steps were already tried, compare against known Windows issues before making more changes. Review Windows release health for the installed build.
The key point is that this symptom usually means Windows cannot validate connectivity status through NCSI, even though the network stack itself is working.
