  1. Very slow upload speeds


    I get around 250-300 Mbps download, but only .02-.05 Mbps upload. I know it's not an issue with my internet or router because i get 30-40Mbps on other devices. The issue persists across both wifi and Ethernet.

  2. Slow upload speed

    I have a cable service which is supposed to provide download speed of 300 Mbps and upload speed of 20 Mbps. My PC is connected to the service providers modem via an ethernet cable. I recently had a problem with both speeds being ultra low. A technician
    visited and traced the problem to a broken copper wire tip on the input cable to the modem. He cut the end off the cable and crimped a new connector on. He ran some tests presumably to check that no other faults existed, reconnected the cable to the modem
    and both speeds ran within the correct ranges.

    The next day I decided to run a speed test and the download speed was fine but the upload speed was very low (down to 1.9 Mbps).

    being curious I disconnected the infeed cable to the modem and checked the new connection. Everything looked fine so i reconnected the cable and ran another speed test. Both speeds were back up where they should be.

    The next day I ran another speed test and the upload speed was low again. This time disconnecting and reconnecting the input cable to the modem did not resolve the problem.

    Sorry for being so long winded here but my technical knowledge is rather limited and I prefer not to play with things I do not understand, but my question, "should I be concerned about the slow upload speed?" It does not appear to be causing any great problem
    but the technician who visited did indicate that a slow upload speed could cause other problems with the modem, such as it automatically rebooting itself. This has occurred twice since the slow upload speed came back.

    Other than going back to the service provider and waiting until they can send another technician out, is there anything I can do myself to resolve the problem?

  3. Slow Download Speed

    Hi,

    Thank you for posting your query in Microsoft forums.

    • I would suggest you to test the speed using any of the speed test website or app to confirm the upload and download speed.
    • I also suggest you to reset the wireless router to check if that helps.
    • You may plug in the Ethernet cable if available and check the speed.


    Hope the information is helpful. Feel free to write to us for any other assistance with Windows, we’ll be glad to assist you
