    Slow WIFI on Surface Pro 5th Gen


    My wifi is extremely slow compared to my cell phone. Phone gets 400 mbps with speedtest.net, Surface Pro gets less than 100 mbps. I went through all the Microsoft recommendation with no change. I went looking for a new driver from Marvell and found none.


    My current driver is:

    Provider: Marvell Semiconductors, Inc.

    date is: 1/21/2020

    driver version: 15.68.17018.116


    So I thought I'd try going back to the first driver shipped with my Surface and low and behold, my wifi got to 355 mbps. So I then picked a prior driver date:2/9/2017, ver:15.68.9114.29 and it too worked well. So apparently the 15.68.17018.116 driver slows things down.

    How to rollback your driver:

    1. select Windows Key and x

    2. select Device Manager

    3. expand Network adapters

    4. right click on Marvel AVASTAR Wireless-AC.........

    5. select Properties --> Drivers --> Update Drivers

    6. click on "Browse my computer for drivers"

    7. click on "Let me pick from a list of available drivers ........"

    8. make sure "Show compatible hardware" is checked

    9. the driver at the top of the list is your current installed driver, so select a driver below it, click on Next, driver will install, click on close.

    note: Before you reboot, you can see the driver version by repeating steps 4 & 5 above.

    10. reboot to activate


    Hope this works for you as well.

    :)
