    Hi,

    i recently updated Windows to 1903. After the update and even a 1903 clean install the transmition of data through a Thunderbolt Network is unaccaptable slow. The Windows 10 Client can receive data through the thunderbolt Network in a normal Speed (3-700MBs) but sending data only (20-30 KByte/sek). My other NIC RJ45 1Gbit Ethernet functions normaly (112/110MB).

    Here is the Output of netio:
    Server:

    Done.

    As you can see, the transmition of data to the Server or the reading of data from the Windows Client is Pretty slow. Does someone have the same issue? What can be the issue?

    In such cases the usual suspect is driver,especially if everything was working fine earlier & only change was OS update.Try some older versions(or some latest versions of driver even if beta).

    I know, but I just cannot find the proper Driver. This is the latest Driver I have found so far:
    thisissomelink dell.com/support/home/de/de/debsdt1/drivers/driversdetails?driverid=tbt79

    After install the TB Networking Driver is from december 2018. Someone has a current Driver link?

    Try searching on google using device hardware Id value as shown in device manager--driver properties--details.

    I did. I tried the following Driver versions with all the same issue:
    WHQL:
    1.41.648.5
    1.41.645.0
    1.41.565.0

    Intel:
    17.4.79.510
    17.4.77.400
    17.4.76.300
    16.3.61.275

    Then I guess you need to wait for someone here using TB with v1903 to confirm this.Try some recent dell system launched a bit late after release of v1903 & with similar TB connector to see if it got some newer driver.

    Cannot be, because my 1Gbit NIC has 112-115 MB both ways.

    Maybe the issue is in the upgrade, try clean install if everything else fails.

    I did try a clean install, no help.

    What do you mean? Why should my other 1GBit NIC be responsible for the slow data Transfer of another NIC?

    if your nic is working properly it cant be a driver issue...must be something else.

    My 1Gbit is functioning correctly but not the TB NIC. I thought, if the 1 GBit NIC functions then it cannot be the Firewall or AntiVir. So it has to be a Driver issue. But I tried over 8 different Drivers.

    I mean that you should look at something else what is causing the problem not the drivers and prob not the NIC

    This is why I opened this Topic. No AntiVir installed, Firewall off, clean install. What can it be?
