My Win 10 machine has upload speeds under 1Mbps when using an Ethernet connection. Wireless upload speed is 15-20Mbps. Safe mode Etnernet connection is also 15-20Mbps. Here's what I've tried: Install latest network card driver Run the network troubleshooter - no problems found Followed the netsh and ipconfig commands at https://answers.microsoft.com/en-us/windows/forum/all/upload-speed-is-slow-only-on-win-10/fd9c7c38-c84d-4791-a77d-c480fea05875 Reset connections via Start > Settings > Network & Internet > Status > Network reset Any other ideas?

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

Thank you! All sorted ☺️👍

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.
