    Lost Ethernet Connection with Windows October 2020 Update


    I just installed the October Update and the Ethernet connect is lost. Basically when I go to open the browser, I lose connection, actually the router (Nighthawk X10 AD7200 Smart WiFi Router) just reboots over and over.

    At the same time, when the browser is open and I get the message "Your connection was interrupted" , I run the Windows Network Diagnostics I get the follow results.

    System Specs
    Alienware Area-51 R5 PC
    Nighthawk X10 AD7200 Smart WiFi Router
    Killer E2500 Gigabit Ethernet Controller

    Here is what I've done to date:
    1. Went to Dell download latest drivers, no change
    2. Searched the Diagnostics error and tried those fixes
    3. If I pull the Ethernet line and run on WiFi, No Problem.
    4. Uninstalled the update, and the problem went AWAY!

    It seems like a problem with the update, especially when I uninstall the update the problem doesn't exist but who knows.

    Any suggestions would greatly be appreciated.

    Hello @gzt7d8 Greg,
    It seems like the logical next step is to uninstall the October update and see if that fixes the problem - yes, I realize that sucks, but let's see if it fixes the problem, right?

    That's not a Windows problem, it's a router problem.

    Of course if the router is having issues, your computer will have issues.

    Check the router log for clues.

    I've done that and the problem went away, that's what is so puzzling.

    Yes that is a very possibility, but I've uninstalled the October Update and the problem went away. That's why I thought it might be the update. I'm trying to figure out who is the culprit.

    What's puzzling about the router, is the modem has one IP Address and the Router has a different IP Address. I thought the router got the IP address from the modem. I've tried releasing and renewing it through the router but no luck.

    I'm going to reset the router and see if that helps.

    It makes sense that they each have a different address as they are two different IP devices on the same network. Not sure how the router gets its address - maybe the modem gives it static address that's why it's not charging.

    I reset the router and the problem is fixed. Very confusing but it has been resolved.

    Thanks for your assistance.

    Is it working with or without October CU installed?

    Great. Well that was a bizarre coincidence that the router went nuts after you installed the CU.

    Lose Internet access every couple of days


    I have a similar issue ever since Microsoft forced the 2004 update onto my Windows 10 computers and the 20H2 update has not fixed this issue. I have it narrowed down to a DNS issue, I still have a connection to my router and all other non Windows devices that are connected don't have the issue, it's only my 2 Windows 10 computers this happens to and I have to reboot them every couple of days to correct the issue. The Windows troubleshooting tool doesn't find anything wrong. I've already installed the latest NIC drivers for my Realtek ethernet adapter and it's still happening. This issue only started occurring with the 2004 update.
