    QOS scheme & LLTD can cause this. Also depends on what site they are using to do their speed tests and who their provider is. Along with any third party Internet Security software.

    My guess is that the ISP is throttling traffic. I would run "Shaperprobe", to see if the ISP is doing any type of throttling. M-Lab

    Windows 8 64-bit


    Ok I ran the M-Lab program and the results are as follows;

    Normal Mode

    Estimating capacity:
    Upstream: 11,201 Kbps.
    Downstream: 102,354 Kbps.


    Upstream: No shaper detected.
    Median received rate: 10,976 Kbps.

    Downstream: No shaper detected.
    Median received rate: 186 Kbps.

    Safe Mode

    Estimating capacity:
    Upstream: 12,139 Kbps.
    Downstream: 111,731 Kbps.

    Upstream: No shaper detected.
    Median received rate: 11,946 Kbps.

    Downstream: No shaper detected.
    Median received rate: 105,690 Kbps.


    So something is happening in normal mode then.

    That again would be QOS scheming and/or LLTD. Still need to know if there is any third party Internet security software. Download and run Speccy. You can get it from Download Speccy - MajorGeeks After you run it, you will get a URL at the end. Copy that URL and paste it in a post on here.
