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.

    Where did you find this version of the driver available? I didn't see it on the Realtek site.

    I was able to just use the 'Roll Back Driver' button via Device Manager. It wasn't greyed out when I had the newer driver.

    The way I fixed it was by rolling back to a previous version of my Realtek network adapter driver.
    Here's my driver:

    The version that caused this issue for me was:

    1153.6.418.2022 (there could be other versions that are having this same issue)

    Dated: 4/19/2022

    The version I rolled back to which fixed the problem for me was:
    10.38.117.2020
    Dated: 9/26/2015

    Could be other newer versions that fix the problem but this worked for me and I've already wasted to much time trying to troubleshoot it.

    Hopefully this helps!

    Thank you!

    As I've mentioned in other posts, I had tried nearly everything to solve this problem. But I had not tried rolling back the Realtek USB ethernet driver.

    I had also been running the 4/19/2022 version previously. I was able to find a previous version on Dell's website (2.45.2020.214, A00 from March 2020).

    After rolling back, my Ethernet has not lost its connection for over 20 hours according to the Internet Connection Monitor Chrome plugin. Usually, it disconnects in under 5 minutes.

    Crossing my fingers that this end-around continues to work until a driver or Windows update permanently fixes the problem.

    Note: As far as I know, I am not running a VLAN on my home network. No evidence in my modem/router config screens. But I have so many access points and (unmanaged) switches in my network that I can't say for sure.

    Did you find a resolution to this problem? I confirmed only Windows 11 computers are having this problem. We also have vlans setup. Is there any configuration that will help or just unplugging the etherport?

    USB to Ethernet adapters worked for us. It's a crappy workaround but I don't think there is anything else we can do until Microsoft fixes acknowledges it, and then actually fixes it.
