    Maybe their driver monitors/modifies the settings, not sure. The TCP Optimizer uses standard Windows PowerShell cmdlets and netsh commands to set those, all documented. How do you determine they are not modified? The fact that they are not read at program startup does not mean they are not modified.

    It is possible... You may also want to try the PowerShell cmdlet:

    Set-NetOffloadGlobalSetting -Chimney enabled

    Chimney offload is deprecated, it should probably be disabled anyway.

    I assume you right-clicked on PowerShell and chose to "Run as Administrator" before running the command? Otherwise you wouldn't have the rights to change a lot of settings.

    If you tried as admin, it may not be available with your adapter or version of Windows. As a matter of fact, I get the same error for " -Chimney enabled" on my current Windows machine.

    I tried to run "Run as Administrator". Its all not working. Soo if its depenting on the windows version. I'm using windows newest. Its meaning tcp optimizer working wrong. . Looks like u r profesional here. I need to check my network... what command to cmd do u know or some things to check my network?

    Ok... I'm here because I'm playing counter strike shooter and I have very bad bullet registry. I'm using wifi, signal not bad 4/5. Ping in game 5-25.(In local test ping 1-2) Soo I'm searching what is wrong with my network, I'm sure its something wrong. I dont have packet loss, or choke, lag. But its something not clear.

    I tought its maybe because of my wifi adapter. I changed it to "gaming wifi adapter". Its same...
    There in adapter many settings.

    https://www.intel.com/content/www/us.../wireless.html here is description of the settings. I'm not sure what settings is best.


    ARP offloading for WoWLAN
    Fat channel intolerant
    Global BG scan blocking
    GTK rekeying for WoWLAN
    MIMO power save mode
    Mixed mode protection
    NS offloading for WoWLAN
    Packet Coalescing
    Preferred band
    Roaming aggressiveness
    Sleep on WoWLAN disconnect
    Throughput Booster or Throughput Enhancement
    Transmit power
    U-APSD support
    Wake on magic packet
    Wake on pattern match


    And I need some tips & settings for windows 10, for network tweak. Maybe boost somehow...
