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?

Wow - fixed me too. Never thought of checking that the wifi worked but the PC didn't!

Surprised I figured it out. My PC (Dell) uses the Killer E2400 Gigabit Ethernet Controller. Turning off the Killer Prioritization Engine fixed this problem. I had to do the same till I got this latest version of the killer Performance Suite which seems to not affect my E2400 ethernet anymore. My Upload speed is now the one promised by my provider without disabling the Prioritization Engine. 👍

Your solution worked! I turned off the Killer Prioritization Engine (in Killer Intelligence Centre) and my upload speed went back up to normal high speed. Many thanks. DELL XPS 8930

I have the same issue. Tried everything .thanks ,life saved

I have the same issue. Tried everything .thanks ,life saved Glad this worked for you! The Killer software eventually came back on my PC. Solved that by telling the Killer* services to only start manually, so they never do.
