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.

    Mine started happening immediately because I just received the laptop in July and it came with Windows 11.

    I'm curious about the timing of the problem for everyone on this thread.

    In my case, I bought my Dell XPS 15 in November 2021. It came with Win 11 Home pre-installed. I immediately upgraded to Win 11 Pro.

    From Nov 2021 to May 2022, my Ethernet worked flawlessly. Then, around May 28, the disconnection problems started out of the blue. The timing did not line up with any OS, software, or hardware changes. Also, no changes to my network setup at that time. The same setup that previously worked fine just started failing.

    What about you? Did it happen right after upgrading to Win 11? Did it happen from the start on a new Win 11 machine? Did it work for a while and then mysteriously stop?

    So technically the only workaround I found was using WiFi.

    We have 3420 Dells, so we actually found that plugging the ethernet into the dock was the "fix." We still haven't found anything on our surface devices (Surfacebook2, Surface laptop 3 and Surface Laptop 4) all have this disconnection issue. We have been telling our users to not to update to Window 11s. If they, then we tell them to disconnect the ethernet and use WiFi. I have been having this issue at my org for about 2 months and I have no idea. Something up with the network is only thing left that we didn't touch.

    Yes! I am using a docking station. And unfortunately, since it's a new machine, it doesn't come with an ethernet port. Is there a workaround for this?

    Do you have this issue with the ethernet connected to the device, or some sort of docking station? We're having this issue with Windows 11 Devices when they're connected to a dock (Dell and Microsoft Surface Docks). We're looking into the dock stations, but there are no issue with Windows 10 devices. We have a feeling it is something with the VLANs or something else.
