So yesterday I installed the new update and now my ethernet isn't working..

I already tried network reset and the netsh/ipconfig commands (yes in administrator cmd)

Already tried to uninstall the update and still nothing..

Another thing is.. my start button throws a critical error at me now.. and I can't open it..

I tried to run sfc /scannow but that didnt find any violations so I am at a loss..

Also tried safe mode but still no connection (all tho i don't know if there should be any in safe mode)

And yes I also tried to restart my router and all of that..

Also my wifi is working so it can't be an issue with that right?

Now I tried to restore my pc to the was it was 5 days ago and still nothing.

Is there anything I can do to fix this issue?

    Hi Karel,

    I have reviewed the issue, and from my understanding If your Windows 11 PC can't connect to the ethernet after an update, it could be due to various reasons like driver incompatibility, network settings being changed, or issues with the update itself. Here’s how you can troubleshoot and potentially resolve the issue:

    Step 1: Check Physical Connection

    • Ensure the Ethernet Cable is Properly Connected: Make sure the ethernet cable is securely plugged into both your PC and the router/switch.

    • Test with a Different Cable or Port: Try connecting with a different ethernet cable or port on your router/switch to rule out hardware issues.

    Step 2: Verify Network Adapter Status

    1. Open Device Manager:

    o Press Win + X and select Device Manager.

    1. Check for Network Adapters:

    o Expand the Network adapters section.

    o Look for your Ethernet adapter (e.g., "Realtek PCIe GbE Family Controller").

    1. Check for Driver Issues:

    o If there’s a yellow warning triangle or red cross next to the adapter, it indicates an issue.

    o Right-click on the adapter and select Properties to check the status.

    Step 3: Update or Rollback Network Drivers

    1. Update Driver:

    o Right-click on your Ethernet adapter in Device Manager.

    o Select Update driver > Search automatically for drivers.

    o Restart your PC after the update and check the connection.

    1. Rollback Driver:

    o If the problem started after a driver update, right-click on the Ethernet adapter.

    o Select Properties > Driver tab > Roll Back Driver.

    o Restart your PC and see if the issue is resolved.

    Step 4: Reset the Network Configuration

    1. Open Command Prompt as Administrator:

    o Search for "cmd" in the Start menu, right-click, and select Run as administrator.

    1. Execute Network Reset Commands:

    o Run the following commands one by one:

    netsh winsock reset

    netsh int ip reset

    ipconfig /release

    ipconfig /renew

    ipconfig /flushdns

    o Restart your PC and check the connection.

    Step 5: Uninstall Recent Windows Update

    If the issue started after a recent update, it might be worth uninstalling that update:

    1. Go to Settings:

    o Press Win + I to open Settings.

    1. Navigate to Update & Security > Windows Update.
    2. Click on View update history > Uninstall updates.
    3. Select the recent update that was installed before the issue started and uninstall it.

    Step 6: Perform a Network Reset

    1. Go to Settings:

    o Press Win + I to open Settings.

    1. Navigate to Network & Internet.
    2. Scroll down and click on Advanced network settings.
    3. Click Network reset.
    4. Follow the prompts and restart your PC.

    Step 7: Reinstall the Network Adapter

    1. Open Device Manager:

    o Press Win + X and select Device Manager.

    1. Right-click on the Ethernet adapter and select Uninstall device.
    2. Restart your PC. Windows should automatically reinstall the adapter driver.
    3. Check the connection status after restarting.

    Please let me know if you need further assistance, and keep me updated.

    Best regards,

    Arvind

    I don't have any way at the moment to connect my pc to wifi but other than that wifi is working normally. Nobody has any issue with it.

    I just want to confirm—are you experiencing the issue where the Ethernet cable is not being detected at all, or is it being detected but shows “No Internet”? This distinction can help narrow down the troubleshooting steps to resolve the issue effectively.

    Yeah so I did everything you suggested and still nothing I even bought a new ethernet cable but still nothing.. when I do a diagnosis it says that no cable is connected but I have a new pc. I don't move the cable in any way so I don't think its broken.. it also worked 2 days ago.. I turned my pc off (it installed the update) and when I turned it on in the morning there was no internet connection... So I don't know what to do.

    What update?

    Assuming a branded PC

    Win11 by default only installs critical security updates, unless you made the mistake of selecting “Get latest updates” which includes drivers.

    See your laptop/PC makers support to update both bios and ALL drivers.

    There should be a shortcut to that makers update utility on your system.

    Then set Bios to defaults & Pwr to balanced. At the end of the day shutdown, do not leave in sleep.

    Do NOT update from any other source inc Device Manager
