    Lost Ethernet Connection after Windows Update


    Windows update yesterday. Immediately after I noticed my network connection had switched to Wireless icon. When I checked Device Manager, my ethernet adaptor was missing (Realtex PCIe GBE Family Controller) Eventually discovered it in "Show hidden devices". In Properties under General it says "Currently this hardware device is not connected to the computer (Code 45). To fix this problem reconnect this hardware device to the computer". How do i do this? After a major amount of Googling it appears that this is a fairly common problem with Window 10 updates - people suggest that the BIOS has been changed. I am in completely new territory here - I don't even know how to access my BIOS, let alone "change" it.

    I would be very grateful for any help at all!

    :)

    Loss of Ethernet connectivity after update.

    I lost the use of my Ethernet connection after the automatic critical update to my Windows 10 of two days ago. My wireless connection still worked. When I restored my system to pre-update status, my Ethernet connection was restored. I assume at some
    point soon the automatic update will occur again. What do I do to prevent the loss of my Ethernet connectivity?

  3. Windows 10 Creater update

    After the Creater update on Windows 10, and after the restart, I lost sound, and I lost connectivity to the internet (both ethernet connect and wifi). The only fix was uninstall the update. I got both the sound and internet back but some of my Windows
    apps don't work. I tried uninstalling and reinstall, but it tells me "Acquiring license, then Mapping your download, getting download data, calculating download size, almost ready, then downloading. But it stays there and never downloads.

    I see there are quite a lot of issues with this update. Please help.

    Lost Ethernet Connection after Windows Update

    I would suggest trying sthg simple... in Control Panel, Device Manager simply right click the driver, uninstall, restart.

    Hopefully Windows will detect it and reinstall the driver.

    There is still the possibility of a simple physical connection problem, so as yours is a desktop, that would be the next thing to check.
