Windows 10: Network Sharing Centre says Not connected, but PC has internet access?

    Network Sharing Centre says Not connected, but PC has internet access?


    I have a Win10 Pro machine upgraded from Win7 Ultimate. All was well with Win10 until the network and sharing centre stopped believing I was connected to the internet, despite being able to connect just fine. That is, the "View your active networks" just says "You are not currently connected to any networks", but my ethernet adapter settings say I'm connected, and indeed I am.

    For a while, this was "OK" because seems to have been operating as a Public network, but now it's completely gone and I cannot get network shares to work at all. This is now causing hassle!

    I have tried:
    • Disabling the adapter and Enabling again.
    • Uninstalling the adapter and reinstalling it, with a reboot.
    • Tried all the network troubleshooters, multiple times. They all report 'couldn't identify the problem'.
    • Running "netsh winsock reset", and also "netsh interface ipv4 reset", "netsh interface ipv6 reset", with reboot
    • Reinstalling the adapter from the latest Intel i218-V driver (was using 2015 MS driver), with reboot.
    • Restarting multiple services, such as the Network List service.
    • Running the intel adapter selftest suite: no issues found.
    • Resetting some services to be "Automatic" start from Manual.
    • Removing a bunch of registry keys in the HKLM\System\CurrentControlSet\Network tree and forcing their regeneration by reinstalling the ethernet adapter driver again.


    My only hint of success is that when I reinstalled the adapter driver, for a second or so the view active networks did change to suggest it was looking for a location, but then very quickly reset back to 'not connected'.

    I'm getting a bit desperate....

    Is this a real bug in Win10 or is there some config setting that can be changed or reset?

    If (and I really don't want to, because it will invalidate at least one software license) I had to reinstall Windows, how would I do so given that I only have old Win7 install media?

    Do MS have any useful support service these days?

    Try running this as admin to see, if it helps. Mine network normally shows Not Connected and this enables it.

    Thanks for that. The first part ran fine with nothing unexpected; the remainder did this:

    Code:
    C:\WINDOWS\system32>wmic path win32_networkadapter where index=0 call disable
    Executing (\\SHERLOCK\root\cimv2:Win32_NetworkAdapter.DeviceID="0")->disable()
    Method execution successful.
    Out Parameters:
    instance of __PARAMETERS
    {
            ReturnValue = 0;
    };

    C:\WINDOWS\system32>
    Not sure if this was expected or not, but no change in the COnnected status is visible.
