    I own a Surface Pro 2 and it runs the latest Windows official release. My network is working with 50 MBits. Only my SP2 is unable to work fine with that network. It reaches a maximum of 30 MBits while connected via Wi-Fi.

    I had that problem im the past, after upgrading to Win 10. I did several clean installs and at a point I’m unable to tell “why”, it works with up to 46 MBits. After a Win update, don’t know exactly which one, the issue is back and I get only 30 MBits down.

    This issue only exists on that SP2. All my Chromebooks, Smartphones and Tablets are fine. I did a network-reset, but no solution.

    Do you know any possible option to fix this?

    you may need 20minutes to fix those.

    step 1. connect to your inet at least 5minutes and open cmd do the following command:
    netshintipv4set glo minmtu=352
    restart you computer

    step 2. connect to your inet at least 5minutes and open cmd do the following command:
    netshinttcpset glo autotuninglevel=experimental
    restart you computer,..

    step 3. connect to your inet at least 5minutes and open cmd do the following command:
    netshintipv4set glo minmtu=576

    restart you computer ..again please tell me how it work then 🙂

    last updates broke ip connection, use these and restart windows
    open a CMD admin (right click on START windows logo)

    netsh winsock reset
    netsh int ip reset
    ipconfig /flushdns
    ipconfig /release
    ipconfig /renew
