    Win10 capping internet at 20%


    Having an odd problem.
    Win10 latest insider build appears to be capping my internet at 20%.

    If i run ookla speedtest through chrome or ms edge i get close to my full 1 gig connection up and down.

    However if I run the ookla app from windows I barely hit 200meg.

    I have tried multiple network resets and every possible suggested tweak google has offered with no change.

    I have 2 other pcs and they both give similar speeds in bot the browser and the app.

    Is there any way to do a scorched earth reset ?
    Wipe out everything and start with factory settings for services, registry, network card settings ?

    Are you saying you're running the Desktop version of Ookla's Speed Test?

    If so, are you hitting the same test servers as Edge and Chrome?

    Exactly.
    When I run Ooklla through chrome through a browser like chrome on edge it gives me close to my 1gig speed.
    I run the Ookla desktop app and I get approx 200meg.

    Only difference I see is the browser shows multiple connections and the desktop shows single.

    My motherboard is an Asrock z730 Taichi Ultimate with 3 NICs.
    ASRock > Z390 Taichi Ultimate

    AQUANTIA® 10 Gigabit LAN
    Intel I219V and I211AT

    The Aquantia is wired directly into a port on my router, Pace 5286AC
    The two Intel connections are connected into a switch which is then connected into another port on the router.

    My wife's PC is using a single connection, directly into the router and she is getting roughly the same speeds regardless of using browser or desktop Ookla.

    I have tried every ting I can think of to reset my networking, every 'trick' I can find on google, nothing has had any impact.

    I REALLY don't want to do microsoft's usual 'fix' of "just reinstall windows completely from scratch".

    So, any and all suggestions and ideas accepted.

    If I had hair I'd be tearing it out.

    @Bob77 -

    Did you test with these websites and compare to the other systems?

    Browser based examples:

    fast.com
    speedof.me
    testmy.net

    BTW - you can always download the installable Ookla for 64 bit here: It works on W10. It's not the Browser based or Microsoft Store app.

    I said in the original post that the downloaded ookla app is showing 200meg while the browser based ookla is approx 900meg.

    I would also check that whatever security software you're using is not scanning traffic on the Desktop Ookla app.

    Add an exemption for speedtest.exe
