    Intel gigabit CT-desktopadapter - missing driver


    Greetings. As the onboard netadapter gave me an unsatified speed (systeminterrups maxed out one core of the CPU), and after searching for a better driver, I gave up and got a PCIe Intel(R) Gigabit CT-desktopadapter.
    This adapter has the same problem!! And I can't find any driver for this either!
    I have been looking here:
    https://downloadcenter.intel.com/Sea...esktop+Adapter
    But only some tools shows up, no driver at all. And not even these tools I can get to work/show up.

    All this started with windows 8.1. What can I do? (except going back to windows 7 ultimate)

    Hi Burgurne,

    If you have Java installed, you can try this Intel Driver Update Utility which should find the driver you require. Note that I have not yet tested it on 8.1 but I'm guessing it should work for you:

    Intel® Driver Update Utility

    Good luck and I hope this helps you.

    Well, that said there is a newer driver, and download a 32,5Mbyte file. But when I run this file it says that I don't have any Intel adapters in my PC!!
    So how and why the online drivercheck can see my driver is old, I don't know.

    i literally just installed one of these in a workstation and they are great. it was on a windows 7 system though but try this one and see what happens. https://downloadcenter.intel.com/Det...adType=Drivers all they have for 8.1 is utilities which is odd. EDIT what version did it have you download? and it is seen in your device manager right?

    In devicemanager it is seen as "Intel(R) Gigabit CT-desktop adapter". The driver is made by Microsoft (??), and not by Intel.

    From the readme.txt:
    Intel(R) Network Connections Software Version 18.7 Release Notes


    ​But it don't install anything, it just replied that I don't have any Intel adapter in my PC!

    oh sorry i thought you meant that was for the one that you got off the update tool and it says Microsoft atm because its using windows built-in drivers and not intel's. you might have to manually install it. right click it and select update drive then manually look for it. now you need to extract that exe you downloaded to a folder like mine (i used winrar to do this) in the screen shot then select that folder in the next screen and make sure include subfolders is checked, then hit next and it should find the one needed in there.
    best of luck

    Latest Intel drivers for an Intel Gigabit CT card


    I just got through installing this card on a Win7 machine as a test case for an upcoming Win8.1 build.
    The platform was a repurposed Dell clean install Win7(32).
    These notes might help somebody else.

    Start with https://downloadcenter.intel.com/Default.aspx?lang=eng and you will get the Intel Download Center.
    Use the Find By Category selections, Active Products and make selections for questions 1, 2 and 3.
    (1) Select Network Connectivity
    (2) Select Intel Desktop Adapters
    (3) Select Intel Gigabit CT Desktop Adapter

    You should get a page that lets you select the operating system you are interested in. In my case that was Win7(32).
    Select Drivers(7).
    That will get you a list of 7 potential drivers. It turns out that the Win7(32) and Win8(32) drivers use the same latest pkg from Intel (Ver19.1 on July 3 2014).
    The latest was Network Adapter Driver for Windows 7* (Win8* for you).
    Selecting Win8* gets you to a Win8* list of 7 driver downloads.
    The date for both was 4/10/2014 and version 19.1.
    Downloading the pkg gets you Intel PROWin32.exe, 21,689KB.

    When I installed the new card and booted, Windows found generic drivers for the Gigabit CT card.
    The driver turned out to be ver 11.05.21 4/6/2009.
    I switched the CAT5e cable from the onboard LAN port (an Intel 82562V-2) to the new card.
    The card and generic drivers functioned ok as is but did not have the latest features from Intel.
    I installed the Win7 driver pkg (PROWin32) as an administrator (no problems, default install selections).
    I did not install PowerShell or SNMP Agent.
    PROSet install was selected by default and I let it install.
    The install completed successfully.
    Boot.
    The Link Speed tab showed up in the Properties for the Gigabit CT card.
    I disabled the onboard Intel adapter.
    Working OK the next day and the Link Speed tab shows info as appropriate.

    There may be easier ways to do this, but this worked for me (YMMV).

    I "patched" inf file of Intel's driver for Windows 8.1 x64 so you can use it with ANS (Vlans, Teaming, ...)
    you find driver here (see _readme.txt inside and sorry if there are mistakes - I translated dialogs to English from Czech Windows):
