    Ethernet keeps disconnecting

    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.

  3. Internet Randomly Disconnects: Ethernet Network Adapter Keeps Disconnecting

    My internet keeps randomly disconnecting throughout the day. Its a Dell (Windows 10Pro 22H2 - Dell Precision 5770) with Network Adapter: Realtek USB Gbe Family Controller Ethernet. I tried these steps below, no resolution yet:

    One thing I noticed, everytime the internet randomly disconnects, I go to Device Manager, and notice the Realtek Network Adapter has totally disappeared from the list (with no option to reenable, even after finding it in Hidden devices).

    I have to go through these two steps in this order to bring back internet.

    1. Restart Computer
    2. and then Restart Modem Router. ( I do restart modem by unplugging/plugging back in).
    If the ethernet disconnects, Restarting the Modem won't work. Neither will Restarting Computer work. It has two be those two steps above in that specific order. I'm curious if having this resolution path, to understand why ethernet adapter disappears. If you can help target or specify why its occurring?

    Already attempted this: and the problem still continues

    1. Updated Dell Drivers
    2. Windows Update
    3. Network Adapter Troubleshooter

    4. (a) Network Reset and (b) tried manually uninstalling/reinstalling network drivers separately
      Windows 11 ethernet keeps disconnecting. ext?url=https%3a%2f%2fi.stack.imgur.com%2fK7cfH.png

    5. Tried manually downloading the software drivers at Realtek website Downloads - REALTEK
    6. Replace cable just in case, but the other computer in home does not have internet randomly disconnect
    7. Tried:
    1. Disable these three in Device Manager: (a) Energy Efficient Internet (b) Green Ethernet (c) Wake on Magic Packet
    I use the modem with another computer, and no issues whatsoever, until I got a new computer.

    Note: this is different from previous question, since its looking at a problem/diagnosis path, rather power management settings.

    Constantly disconnecting with ethernet cable

    Hello,

    Thank you for keeping us posted on the status of the issue.

    I suggest you to check if rolling back the Ethernet driver helps to resolve the issue. Follow the below steps.

    • First of all, Press Windows logo + R from keyboard. It will open
      RUN.
    • Now type devmgmt.msc and press Enter to open Device Manager.
    • You will see all the device list of your PC. Expand Network Adapters
    Rollback driver

    Double click on your Ethernet driver in Device Manager. Then Click on
    Driver tab and select Rollback.

    Important: If your drive is performing well and there is no error, Rollback driver button will be grayed out as an option.

    If it still does not help, I suggest you to reinstall the drivers for the Ethernet driver and check if it helps to resolve the issue.

    Note: Once you uninstall the drivers the Ethernet adapter device will be disabled and you won’t be able to connect to internet. So it is advisable to keep all the installer files as a back up in your hard drive.

    Write to us with the results for further assistance.

    Thank You.
