unable to connect to network after Windows 11 22h2 update

Peter E Lewis 46 Reputation points

I performed the Windows 11 22h2 update today and it updated successfully. However, I am no longer able to connect to my schools internet. I am able to connect to my schools guest internet but not the student one. I've run the trouble shooter, but it hasn't been helpful. Is this an issue with the update or my schools internet. If it is a problem with my schools internet is there some way that I could uninstall the update (I am unable to do it through settings) so that I could go back to when it did work?
Thank you!

    We have had the issue as well. I believe the problem is due to the fact that the RDS connection is trying to connect over UDP and is not trying to connect over TCP if the UDP fails.

    If you add the following registry setting the Remote Desktop Connection will work.
    Have to set this value to 1 in the registry for Windows 11 client to work outside the network
    Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client
    KEY VALUE - fClientDisableUDP SET TO 1

    I am on the early adopter program with Microsoft and raised this exact issue with Microsoft when the beta came out for Windows 11 and they did not fix the issue.

    Hello there,

    If this is caused by the update you can try to restore the PC to the older date, the date before the update was done.

    To restore from a system restore point, select Advanced Options > System Restore. This won't affect your personal files, but it will remove recently installed apps, drivers, and updates that might be causing your PC problems.

    You can get detailed steps from here https://support.microsoft.com/en-us/windows/recovery-options-in-windows-31ce2444-7de3-818c-d626-e3b5a3024da5

    Ways to fix-

    1. Manage the Network Drivers on Windows 11
      In many cases, connection issues such as the "Windows can't connect to this network" error can be resolved by updating your PC's network drivers. However, if you recently updated the drivers and the error appeared soon afterward, you should roll back the drivers to the previous version until the new ones are fixed. You can also try reinstalling the drivers to see if that fixes the problem.

    All these actions can be performed using the Device Manager, so let's dive in and try some fixes.

    1. Update Network Drivers
      To update your network drivers, perform the following:

    The network adapters section in Windows Device Manager.
    Open the Run application using the Win + R shortcut.
    In the text box, type devmgmt.msc and press Enter to open the Device Manager.
    In the Device Manager window, expand the Network adaptors section.
    Right-click on the wireless adaptor for your device, and click on Update driver.
    On the next window, choose Search automatically for drivers.
    Windows will download and install the latest drivers for your device.

    1. Roll Back the Network Drivers
      If the issue started after you installed a new network driver, here's how to go back to the drivers you had before:

    Driver properties in Windows 11
    Open Device Manager by either using Windows search or running the devmgmt.msc command in the Run application (Windows Key + R).
    Expand the Network adaptors section.
    Right-click on the network driver and select Properties.
    In the Properties window, go to the Driver tab.
    Click on the Roll back driver option. The option will be grayed out if the driver wasn't recently updated.
    Windows will install the previous version of the network driver.
    Reboot your computer.

    1. Uninstall the Network Drivers
      If you want to do a fresh install, first download your network drivers from your manufacturer's website. It's a good idea to do this first before you uninstall your current network drivers; once they're gone, you won't be able to connect to the internet through that network adaptor until you reinstall its drivers again.

    Once you have your new drivers ready, it's time to scrub away the old one:

    Uninstall driver prompt in Windows 11.
    Open Device Manager.
    Again, expand the Network adaptors section.
    Right-click the network driver.
    Click on Uninstall device.
    Check the Attempt to remove the driver for this device option.
    Click on Uninstall.
    When you reboot your PC, Windows will automatically reinstall the driver.

    1. Disable IPv6
      IPv6 is really not needed for most connections unless explicitly specified by your router or ISP. So, you should disable it and try connecting to the wireless network again.

    Here is how you can disable IPv6 on your computer:

    Wi-FI properties in Windows 11.
    Locate the network icon on the System Tray.
    Right-click on the icon and choose Network and Internet settings.
    Click on Advanced network settings.
    Under Related settings, choose More network adaptor options.
    Right-click on the wireless network, then choose Properties. Ensure you have admin privileges.
    Uncheck the Internet Protocol Version 6 (IPv6) option.
    Click OK.
    Reconnect to the wireless network again.
    3. Disable and Enable the Wireless Network Adaptor
    Sometimes, an easy reset of the wireless network adaptor can fix connection issues on Windows. You can do this using the Advanced network options in Windows 11:

    Wireless adaptor in Windows 11
    Right-click on the Network icon located in the System Tray.
    Click on Network and Internet settings.
    Click on Advanced network settings.
    On the next window, choose More network adaptor options.
    Now, right-click the wireless adaptor and click on Disable.
    Wait for a moment, then right-click the wireless adaptor and choose Enable.
    Reboot your PC and try reconnecting to the network.

    1. Release the IP and Flush the DNS Cashe in Command Prompt
      The "Windows can't connect to this network" error can be due to an IP error. To fix this, you'll need to release the IP and flush the DNS cache.

    This may sound complex, but all you need to do is run a few commands in the Windows Command Prompt, and Windows will handle the rest. Here's how to do that:

    Command Prompt in Windows 11
    Type cmd in Windows Search.
    Right-click on Command Prompt > Run as administrator.
    In the Command Prompt console, type the following commands and press Enter after each one:
    netsh winsock reset
    netsh int ip reset
    ipconfig /release
    ipconfig /renew
    ipconfig /flushdns
    Close Command Prompt and reboot your computer to see if the error is still there.
