    I suddenly lost internet connection in my PC a few days ago. I checked with my phone and the internet was still working so the problem was narrowed down to my PC and the ethernet cable. I've done network reset, uninstalled windows updates and tried to install a new driver but none of it worked. The only adapter that I see on my device manager is the Realtek PCIe adapter but it doesn't show on the change adapter options in windows settings. On the ethernet port, there are two LED's. One of it is orange which means the connection/speed is around 1 Gbps data rate and the other LED blinks from time to time which means that there is data transmission occurring. I'm not entirely sure if this cancels out the possibility that the motherboard itself is defective. Unfortunately, I don't have a system restore point to rollback to a state when the PC was fine. I tried testing with another ethernet cable and it still didn't work. I checked for any VPN's that may have been present but found none.

    :)

  2. Ethernet driver thrwing an error "Windows is still setting up the class configuration for this device. (Code 56)"

    Hi,

    I had to reinstall the RealTek Ethernet driver on my Windows 10 [1803] 64 Bit V5.3 2019 machine

    The device manager shows the status as "Windows is still setting up the class configuration for this device. (Code 56)"

    I do not have any VPN connection

    I disabled Anit virus and tried installing the driver and still got the same error

    Any suggestion to resolve the issue

    Thanks

    Windows is still setting up the class configuration for this device. (Code 56)

    Hi,

    My windows 10 system was working fine, but after windows update, TAP-Windows Provider V9 network not able to reinstall.

    TAP network Adapter failed to configure with message "Windows is still setting up the class configuration for this device. (Code 56)"

    Same network adapter was working fine on the same system. Also verified same adapter on another windows system also works fine without any issue.

    This issue started after windows update. Before update same TAP adapter install-uninstall was working on the same system without any issue.

    Also do not wanted to reset network or revert windows update as per solution provided in another forum topics due to other applications working fine on the system.

    Thanks and Regards,

    Manish

    What does Windows is still setting up the class configuration for this device. (Code 56) mean?

    Hi,

    Conflicts with a third-party VPN software is one of the possible reasons why you are having a "Windows is still setting up the class configuration for this device (Code 56)" on each of the network adapter in the Device Manager. May we know if you have a third-party
    VPN software installed? If yes, kindly try to uninstall the software, and restart the computer, and check if you will still encounter the same issue.

    Should you need further assistance, don't hesitate to get back to us.
