Any other ideas?

    Excellent! After a few days of messing about this solved my problem too!

    Only thing is it switches back on when I restart my pc! How do I keep it switched off?

    It stays off with latest killer suite, if that does not work for you, disable Killer Network Service.

    Change it from Automatic to disabled.

    Updating the Killer app to latest version does not fix the issue. I found this article https://www.intel.com/content/www/us/en/support/articles/000058906/wireless/wireless-software.html and discovered that doing the manual uninstall steps of the clean install instructions fixed it permanently. Remove and do not reinstall the Killer app. Of course, as we all know individual results may vary so please don't flame me if it doesn't work the same for you :D

    Works fine with this Killer version 3.1423.302.1 as long as Killer Prioritization Engine is set to Off. 🤷‍♂️

    I did not need to uninstall or do any other settings change. 😉

    I had this same problem - a reboot would turn on the priortization engine. Found this solution from the Intel Community (https://community.intel.com/t5/Ethernet-Products/Killer-Intelligence-Center-Slow-Upload-Speed/m-p/1482295/highlight/true#M33158) 

    TLDR version: run the Killer Software Uninstaller at https://www.majorgeeks.com/files/details/killer_software_uninstaller.html 

    I ran it about a week ago, have rebooted multiple times, and the upload speeds have remained consistently high.
