  1. Massive Wifi slow down on Windows devices with latest updates


    From December 2022, on both my Surface Pro 6 and Pro 7 machines running Windows 11 Pro version 22H2, with all the latest updates KB5020044, I have been seeing massive Wifi slowdown. When wired ethernet download speed is 450 Mbps+, Wifi speed doesn't even reach 4.5 Mbps. Wifi speed is fine on Apple devices so this is a Windows specific bug likely triggered by one of the recent updates. Per Windows update history Surface Ethernet Adaptor driver Realtek - Net - 1153.8.20.608 was updated recently on both Pro machines but Marvell Avastar Wireless-AC Network Controller driver 15.68.17022.122 hasn'

  2. Do windows updates slow down the computer?

    Basically you might as well have the latest stable drivers on a Opticsl disk or usb drive and then updates thst dont bork the os, install updates, then dtivers and leave the system unplugged from ethernet/wifi then set parameters to prevent windows from updating automatically, save a list of settings you adjudted judt incase sn os update resets it to default etc.

    W10 sounds more like a pita than it's worth to install...

  3. Wifi very slow on laptop, but ok on other devices - Windows 10

    Hi Annu

    I've had the same problem as Panayiotis1984. Upgraded to Windows 10 on my Lenovo from windows 8.1 - now the wifi is painfully slow. The wifi still works fine on my other devices (smartphone etc).

    I tried the steps that you suggested but they did not bring an improvement.

    Any other suggestions?

    Wifi Very Slow

    Hi,

    The following are some reasons that may cause of the slow WiFi connection.



    • Corrupted or incompatible drivers.
    • Missing updates.
    • Network connection settings.
    • Hardware or software problems.
    • Inappropriate distance from the router or obstruction.
    • Interference with other devices.


    To isolate the concern, have you checked if the issue persists with other devices? For now, we suggest that you follow the troubleshooting steps provided in this
    article.
