    Fluctuating Download/Upload Internet Speed - up to 50% less


    Hi there. I'm trying to troubleshoot my friend's internet speed that goes from ~150-375 Mbps download and ~15-37 Mbps upload. She's paying for 400/40 and the internet repairman said the speeds going into the modem are fine. She's directly connected (no wi-fi) and the normal speeds are around 220 down/25 up.


    The network card has the latest driver (tried uninstall/reinstall), and I've tried some other things (listed here: https://www.drivethelife.com/windows-10/fix-slow-internet-after-windows-10-anniversary-update.html), but it doesn't seem to make a difference. If it does, the proper speeds don't last long so it just could be a coincidence. I know there is always fluctuation in speeds, but over 50% sometimes is too much.


    Thanks.

    :)

    Slow Download Speed

    Hi,

    Thank you for posting your query in Microsoft forums.

    • I would suggest you to test the speed using any of the speed test website or app to confirm the upload and download speed.
    • I also suggest you to reset the wireless router to check if that helps.
    • You may plug in the Ethernet cable if available and check the speed.


    Hope the information is helpful. Feel free to write to us for any other assistance with Windows, we’ll be glad to assist you

    LAN transfer speed fluctuation

    I recently bought a new Win 10 laptop. I transfered my data from my old win7 laptop to the new one via lan cable. But the copying speed fluctuates between 11 MBPS to 200 KBPS. And am talking about a single large file of about 11 GB. I don't get it. I am
    not using internet connection and only those two computers are connected via LAN. I just wanna know the reason for such fluctuation.
