Ethernet keeps disconnecting

So I just got a new PC, everything works smoothly, however whenever I try to plug in my ethernet, it'll connect for a random amount of time (few hours or few days) and then mysteriously it disconnects.

I try unplugging and replugging it into my PC but with no results. Only when I remove it from the router and replug it in to a different port does it finally connect, but this is only a temporary solution.

Any ideas?

Drivers don't need updating, I've already checked.

    I'm having the exact same issue on a brand new Lenovo (less than a week old) that came preinstalled with Windows 11 pro. I keep getting booted out of Zoom meetings because the Ethernet connection suddenly drops without warning.

    I've done all the steps suggested but I haven't gone so far as a clean install of Windows 11 since, as I said, this is a brand new computer. Is this a glitch in Windows 11 Pro that has yet to be addressed? Any other steps I might take to fix this issue?

    I have the same issue here as well. I have a Microsoft Laptop 3 with a Lenovo Gigabit USB ethernet adapter. I upgraded to Win 11 2-3 months ago and I have been having this same problem. With Win 10 over the past 3 years no issues at all with the ethernet adapter.

    It has to be related to the OS, but having followed all the the advice above, except a fresh install of Win 11, the problem still persists. Is it just a coincidence this many people are having similar issues?

    I have the same issue on my Dell XPS 15 laptop (which worked normally for many months after I set it up). I've ruled out all hardware culprits (Dell even swapped in a new motherboard). I've done every last suggestion in this post and all other tutorials I've found about Ethernet disconnects and "default gateway not available" errors (including a repair install of Windows 11 Pro). My wi-fi connection is fine, but all of a sudden after six months, my laptop cannot maintain a stable Ethernet connection. It disconnects after a few minutes. Sometimes it spontaneously reconnects for a little while before disconnecting yet again. If I remove the Ethernet cable and reconnect it, that will usually restore the connection for a short time. The problem happens whether IPV4 is enabled, IPV6, or both. The only option I have not tried is the nuclear one: a clean reinstall of W11.

    Hi MC_88,

    Apologies if the suggested methods didn't work for you.

    Since the issue persist, kindly perform a repair install of your Windows which fixes the broken system files on your machine.

    1. Download the media creation tool here: https://www.microsoft.com/software-download/win... (click on "Download tool now") and wait for the download to finish
    2. Temporarily disable your firewall/antivirus, then open the tool and select the option "Upgrade this PC now".
    3. Wait until your machine goes to the process of repair install. There should be no worries in performing it since you will select the option to keep your files during the process.

    You may also look into the Windows 10 recovery options(see "Reset your PC"): https://support.microsoft.com/help/12415/window...

    Note: ensure to have a backup of your files

    Please let me know how it goes. Thank you.
