Intro

This webpage describes possible solutions to the network connection problems when Windows 11 Home Edition is updated to Version 23H2 or later.

The problems arise because those versions change the underlying network connection mechanism and make the computer not compatible.

There are many suggested solutions given on the internet, but try those described here first.

Wifi network device not working

After Version 23H2 or 24H2 is installed and in the process of setting up drivers or add-ons, there can be no wifi network connection to download drivers to go further because the network drivers already on the computer are not compatible and there is no way to use the wifi network to download its own drivers.

Do the following:

  • Use another computer to download the network driver, or copy the driver from computer of similar model.
  • Store the driver on a USB drive. The best option would be to have this done before upgrading.
  • Insert the USB drive to the computer to upgrade.
  • Go back to the relevant setting up page and browse to find the driver.
  • Select the driver and install.
  • Continue with the setting up if the installation can make the network device work. 

Inability to connect to VPN server and Samba server

Try the solution described in Install OpenVPN services first.

If the solution does not work, try the following which is to disable security check for Samba connection.

  • Press the Windows icon key.
  • Enter registry to show the item for Registry Editor.
  • Select Registry Editor to open it.
  • Move down to: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters.
  • Click EnableSecuritySignature on the right to open a menu to change the value data to 0.
  • Click RequireSecuritySignature on the right to open a menu to change the value data to 0.
  • Move to: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters.
  • Click EnableSecuritySignature on the right to open a menu to change the value data to 0.
  • Click RequireSecuritySignature on the right to open a menu to change the value data to 0.

If the above parameters do not exist:

  • Click top menu Edit > New > DWORD (32-bit) Value to create a new item.
  • Rename the item as the above.
  • Click open the item to change the value data to 0.

Exit Registry Editor.

Reboot the computer.

See whether the connection can be successful.
