    slow internet upload speeds and computer ethernet connection ?


    so internet download is 370mbps but upload is 0.5 or so. cable guy came and determined upload speed coming out of the modem was 10mbps or more. cable from modem into his test device showed high speed but plug the cable into my computer yielded very slow speed. something happening in the computer? I can install a stand alone ethernet card if needed. what could be happening in the computer to cause this?

    What cable are you using is cat 5 cat 6? Does the cable go close to any power TV, microwave that could effect it? What setting do you have in the network card often full duplex which uploads and downloads at the same time is to fast for domestic routers. Is it a modem or router?

    How did you test the Internet speed?

    Open Edge and type speedtest.net and test your actual download and upload speed

    First isolate any anti-virus/firewall software you have running. I'd do this with Safe Mode with Networking. This mode will disable all the crap that is running on your computer and just leave the bare minimum of OS components running. Now in Safe Mode WITH networking go to speed.cloudflare.com and let that do its thing. May take a good 2 minutes or so to complete. Any upload rate change? What's the jitter like BTW?

    If this test yields your actual paid for upload rate I'd temp uninstall any anti-virus or firewall that might be messing up your TCP/IP stack.

    If it's not anti-virus software or a third-party firewall, then I'd like to have a look at an Autoruns ARN file. This will tell me what you have running in your OS and what may be causing your upload rate to be unsatisfactory.

    Allow Autoruns to load all tabs and then go to File and save the ARN file. Zip that and upload here. https://learn.microsoft.com/en-us/sy...loads/autoruns

    How to Boot Into Safe Mode on Windows 10 the Easy Way


    PS:

    DSL (Digital Subscriber Line) can be problematic if there's water or whatever in the line from the building to the tap. Typically called ingress. Can happen to broadband coaxial cable, too. The cable line to the tap could have ingress and only a competent service tech with the right equipment can test for that. Fiber would be a lot better and that may fix your issue. You'll also have a faster symmetric up and down Internet speed.

    hello F22. bad upload speed was around 0.2
    booted in safe with networking and windows defender still on. got great speed down and up 300/11
    turned off defender and still got 300/11. at least I can use it for work (musician who uploads a lot of files)
    though there is NO sound available in safe mode evidently.

    I made an autoruns file if still needed. the history is uploads were fine then not fine. updated all drivers and that seemed to work. then over a few weeks the problem returned. spectrum shows their box working fine from their end.

    looked into autoruns but did no

    To rule out OS run Ubuntu Live off of a USB to see if the speeds are still wonky.

    have tried multiple ways with or without defender makes no difference. maybe reinstall win 10 or run the win 11 upgrade? get a stand alone ethernet card instead of onboard? did uninstall a few recent programs but made no difference

    Why not just a clean straight-to Win 11 install ? No need to go via 10.

    EDIT : Swap out your drive with a blank/new SSD. Do the clean install to that, keeps your current drive intact in case anything goes pear-shaped.

    Also try @bro67 Linux suggestion above (Mint is a good lite version). Create boot USB and run from that. Do not install, leaves your current system intact. More info if needed.
