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?

So far so good. Nothing else has worked to permanently fix this issue.

My desktop has been fine since i turned off the Killer Prioritization Engine, not 1 hitch, but it sure doesnt say much for microsoft, Dell, and the oweners of KIller software does it.

Interesting. I recently serviced a customers Dell with a similar problem - very slow Internet except in Safe Mode. The culprit was "SmartByte Drivers and Services" a similar piece of junk software pre-installed by Dell (that is ostensibly intended to optimize streaming video). Maybe our info will help others running into this problem.

Intel drivers are bugged out ... Go to your Killer app panel : disable the prioritization engine feature, switch it off and retest you'll see ... On my computer the features is useless since 6 months ago i think it is a bug ... or it is a feature : old drivers at launch were perfectly fined ... Intel(inside) ... You are welcome ... Iam not a MVT professional, just a hacker who knows IT ...

Has anybody had luck with uninstalling the Killer software and having your upload speed not decrease? When I uninstall it, my upload speed drops to less than 1Mb.

Win 10 Pro 22H2, Ethernet upload speed slow, Wireless and Ethernet in safe mode just fine
