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:

Any other ideas?

    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.

    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.

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

    I downloaded the most recent (as of 3/5/23) Killer drivers Killer-PCIe-Ethernet-Controller-Driver_RWTJJ_WIN_33.22.1182_A50.exe and when I ran it I got 3 choices: modify, repair, remove. I chose the remove and after it finished there was a restart and voila DL and UL speeds were at or above my ISP plan! Yay. The driver was 9.0.0.50 and there was no Killer Performance software. I did set a restore point.

    For grins, I did some more research and somewhere along the line I saw Intel (the new owners of Rivet Killer) articles about the MS Store as a source of drivers and also how to prevent it from updating Killer from the Store. I didn't follow up on those leads. I then ran the Dell download again and let it fully install Killer driver and software. The driver stayed the same but the Killer Performance software was now re-installed. And guess whose UL speeds were less than 1.0 mbps again! I used the right click uninstall the software but it did nothing for the speed problem. I suspect the original problem settings of the software were left behind somewhere and the uninstall was far short of a cleaning.

    I re-ran the Dell download as before, did a removal and everything was once again running at top speeds. At no time in all of this did I try the settings for Killer Prioritization Engine or anything else. The Killer Performance software is less than intuitive to say the least. I never found/read a user guide. Maybe if Killer "comes back" I will pursue that angle.

    Meanwhile I would be also interested to know if there are other network adapter drivers "out there" that would work without the useless bells and whistles of the (ahem) performance software.

    Regards to All

    Glad it helped. After I changed that setting I uninstalled the Killer software. Unfortunately it went back to having a slow upload speed, so it’s one more unnecessary app on my PC.
