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?

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

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. 👍

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

Thanks, Mac! Prior to getting your reply, I disabled the three Large Send Offload properties for Killer in Device Manager. That seems to be doing the job for me, but if I have the issue again, I'll definitely give your approach a try!

Had similar experience with the software activated again after using the majorgeeks tool. So this was useless. What I found to work so far was keeping the software installed, and turning the Perioritization Engine off, and also disabling Auto Bandwidth. This will prompt for setting a bandwidth. Set the up and down speeds to something like 1500 MB. This I found on the Dell website at this link: https: //www.dell.com/support/kbdoc/en-us/000135709/slow-internet-speed-using-killer-ethernet-adapters I do have XPS 8930 and this did the trick for me . I hope this works for other models or brands. So far this solution has worked. I have turned the PC on and off for several weeks and the UP and DN speeds are normal at the ISP nominal rates, and those settings at the Killer software have stayed the same. Cheers.....
