    Thank you for taking the time to read my post.
    Feel free to request any other information if needed.

    Please note I am using a TP LINK N900 WIFI card.
    There does not seem to be any CPU spikes in Task Manager's graph.
    There does not seem to be any Network Usage spikes in NetBalancer's graph.

    The following issue is present on my computer using

    Windows 10
    Windows 10 new user account
    Windows 10 Safe Mode with Networking
    Old Windows 7 drive

    The issue is not present on
    Ubuntu booted from USB
    Different computer connected via WIFI

    The issue
    When connected to the router via WIFI, I get two lag spikes, one following the other.
    This occurs at least once every 60 seconds.
    This can be small ~40ms or large enough for the ping to timeout completely.
    The issue began about a week ago.


    What I have tried
    Uninstalling Avast
    Reinstalling Avast
    Reinstalling network drivers
    Resetting WINSOCK entries, IPv4 TCP/IP stack and IPv6 TCP/IP stack
    Updating Windows

    The WIFI is shared between the different rooms in the house. Don't know if other people have the problem or if they even use the internet. The issue is present on both 5GHz and 2.4GHz on only my computer specifically only on Windows but not Ubuntu.
    My girlfriend's laptop, also connected by WIFI to the same router doesn't have the problem. The problem only started recently.
