        Windows 10 2004 seems to have an issue deciding if it is connected to the internet. The System Tray Icon shows the “World” type icon and it keeps insisting that its not connected. From the fact that I have posted this you will realise that its actually working.

        Does anyone know how to fix the issue. Resetting the network has no effect and turning proxy setups on/off etc has no effect and I see a lot of wpad.home errors in my DNS server logs. The DNS server on the system is unbound using DoT and DNSSEC. I had no issues whatsoever with V1909 and the only change is the 2004 update which sneaked itself in this morning when I wasn’t looking via windows update.

        Thanks for any pointers

        I had this happen on a whole bunch of PCs on V1903…

        To ‘solve’ the problem, the following procedure was found to work, for no obvious reason.

        1. In Network and Sharing Centre, click on Change adapter settings
        2. Right click on the Ethernet adapter, and choose Properties
        3. At the top, choose Configure
        4. Select the Advanced tab
        5. Select IPv4 Checksum Offload, which will probably be set to “Rx & Tx Enabled”
        6. Change this value to Disabled, and click OK
          After a few seconds, the ‘world’ icon in the system tray should change to the normal ‘rectangular’ icon.
        7. Now change the IPv4 Checksum Offload setting back to “Rx & Tx Enabled” and click OK.
          Having waited a few seconds, there should be no change to the system tray icon.
        8. Things should now have returned to normal!

        I’ve had this issue with multiple machines over the last couple years but never with mine… until I upgraded to 2004. Tried all of the fixes, rebooting router, reset  and new drivers and nothing seemed to work. Then all of a sudden yesterday it was fine.. until I rebooted!

          I think MS has had a problem with that off and on since the pciclearstalecache days. I run into it here and there, not just on Win10, but Win7/8.1 too.

            Have never seen it myself until 10, although I’ve read numerous reports from 7 on. The other weird thing I notice with 10 is if a machine connects via wireless to the router, the LAN connection name will sometimes be changed from “Network” to the name of the wireless network SSID. Can be aggravating! Windows 10  definitely prefers wireless over wired connections it seems.

        I tried your suggestions but the WiFi adapter does not have those options. What I did find however was the when the Windows Sandbox is installed it runs a Hyper-V virtual adapter which does have those options. However changing them made no difference. I then uninstalled the Sandbox rebooted and that made no difference either. I reset the network, still no joy. I then uninstalled and removed the drivers when prompted all the items in device manager under the network branch and rebooted. It was then working as it should. Windows then decided it wanted to update the WiFi Adapter Driver – and then it looks like the install fails (each time) and when that happens things go wrong. It seems it is a Microsoft Driver Issue See this link:

        The driver installed at the moment is:

        V15.68.17018.116

        looks like it will be a while before it gets fixed – not sure how long it will work for time will tell.

        Thanks all for your suggestions.

        Hi,  I too ran into this problem on one of my laptops while testing 2004. I tried many many things and eventually –   This is what I did to fix the issue for me (and it so far worked).

        Note that I have Fast Startup disabled so your mileage may vary if this is enabled for you.

        Regedit > Computer > HKLM > System > CurrentConmtrolSet > Services > NLASvc > Parameters > Internet

        Change the value of EnableActiveProbing from DWORD 0 to DWORD 1

        Reboot
        Voila

          I think this workaround refers to msftconnecttest.com poping-window on the start of Windows system. But it could work somehow to fix @RayG ‘s issue, if this probing defines system try icon status and if it is disabled in his registry.

           

          Also you can try type

          nslookup

          into elevated cmd, you will see what DNS are you using

          then type

          exit

          and flush cache by command

          ipconfig /flushdns

          Then restart your PC

        Regedit > Computer > HKLM > System > CurrentConmtrolSet > Services > NLASvc > Parameters > Internet

        Change the value of EnableActiveProbing from DWORD 0 to DWORD 1[\quote]

        I will try this to see what happens.

        I am using unbound as a local DNS server which is started as soon as the interface gets an IP address and it is also using DoT + DNSSEC which is also working correctly.

        nslookup http://www.microsoft.com
        Server: localhost
        Address: ::1

        The NSLOOKUP command won’t do anything – it’s just informational – but IPCONFIG /FLUSHDNS might. Try that before the registry change.

        cheers, Paul

        All – thanks for your suggestions.

        Nothing suggested has worked, it’s strange as sometimes it appears to work and then 10 minutes later its gone again.

        Latest updates did/do nothing. The system is still useable its just got one or two annoying issues at this time but they can all be worked around. I even tried using the Media Tool to reinstall windows (keeping apps/files and settings) and that again made no difference. The windows .old folder had also gone, I read that some times when that is automatically removed by windows things are resolved, again that made no difference.

        Look like a waiting game…
