    No internet connection after upgrade to Windows 10 Version 1703

    I was running Windows 10 Version 1511 on two of my PC’s without any problems. However, when I upgraded both PC’s to the Windows 10 Creators Update Version 1703, I found I could no longer connect to the internet.

    On the one PC, the following error message appears repeatedly: “The modem (or other connecting device) is already in use or is not configured properly”.

    And on the other PC, this message also appears repeatedly : “After 1 minute automate to connect to the internet”.

    What could be the problem? Has anyone on this Forum a solution? Online there are hundreds of posts with the same problem and I have tried everything suggested on the various forums but in vain.

    Ipconfig /all

    As stated, Press the Win key+X and chooseDevice Manager, Here, are there any yellow flags? Especially under Network Adapters? If so, you will need to download drivers from the computer/motherboard manufacturer.
    Also as stated, press Win key+X and choose Command Prompt (Admin) In the elevated Command Prompt type
    Ipconfig /all> 0 & notepad 0 and press Enter. Copy the text in the notepad results and paste it in your next post.

    Thanks for the prompt responses. No, there are no yellow flags in Device Manager but all the drivers must be fully updated as I had just upgraded to Version 1703 using the Microsoft Media Creation Tool. Anything else I can try?

    WE need the contents of ipconfig /all so we can the state of the network

    what kind of Network adapters do you have installed on your Win10 computer, MikeSA?

    expand the Network adapters section of Device Manager and tell us what Network devices you have on your computer?

    And also what kind of computer are you using?

    try installing at least the August 2017 Cumulative Update - KB4034674 for Windows 10 v1703.

    Thanks for the responses. Herewith are screenshots I have captured using the Snipping Tool. Besides the ZTE modem, I have also tried the D-Link 3G modem but still I cannot connect and troubleshooting cannot identify the problem. I have also connected an ethernet cable but, after awhile, it simply states "Unidentified Network".

    Both my PC's are mid range dual core with Intel Pentium processors and should connect easily to the internet, so what possibly could be the problem?

    Thanks for your further response. It is unlikely that the two modems or the router and the ethernet cable are faulty as everything works fine on my Windows 8.1 PC.

    Even, prior to upgrading from Windows 10 Version 1511 to Windows 10 Version 1703, I had no problems connecting to the internet with the same modems and the router.

    In the circumstances, it appears logical to deem Version 1703 of the operating system buggy and the only alternative is to switch back to Version 1511, would you agree?

    What is strange is that on the one PC, the router LED is green and status is reflected as connected. But when attempting to open a webpage, it states "You are not connected to the internet".

    Have you rebooted the modem/router? By that I mean unplug it from the wall outlet for 5 mins. If that doesn't work, I would try resetting the modem/router......there's a tiny pin hole on the back of the modem/router. Use a paperclip and insert into hole and push and hold down the reset button until the modem/router goes off and comes back on then release the button.
