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.

    Mind you that all kinds of things can cause ethernet to randomly disconnect. I've even seen ethernet cables slowly pop out and a random disconnect then reconnect from a bad jack where replacing the jack fixed it.

    I am seeing no ethernet disconnections on Windows 11. Haven't seen a single one from that since release all the way to 22h2 using Realtek. So it would be hardware specific or a messed up Windows installation if its involved in the OS.

    The router can also cause disconnects and other weird things. This too can be hardware specific, can happen after its automatic firmware updates, etc.

    Networking is complicated :)

    For VLAN issues, we found that connecting the ethernet cable directly to the device works. You cannot use an ethernet port on a dock or USB Adapter. Those will result in internet disconnection issues.

    Right. I forgot that USB adapters didn't work for everyone here. They work for us, for whatever reason. Which is good since only 1 of our current laptops has a dedicated Ethernet port. Who can say whether it's the adapter, device, network or some combination, but all docking stations and laptop models here have had this issue with Windows 11. Windows 10 and Linux are unaffected.

    We haven't tried a USB C to Ethernet, only USB A to Ethernet. However, the USB A to Ethernet failed. Which Adapter are you using? I wondering if we're just using a cheap one, but we don't want to start buying random stuff for no reason just for testing.

    It seems that both have worked for us. One of our users bought himself a USB-C to Ethernet adapter. Since that seemed to work I requested an order of the same model but it looks like we got Amazon Basics USB-A to Ethernet instead. Both seem to do the trick here, I deployed them to the affected users weeks ago, haven't heard any complaints about the network since. I don't know what to tell you.
