Hi 张宇,

The network disconnection is a documented service dependency conflict in Windows 11 version 24H2, rather than an issue strictly caused by the KB5089573 patch or a failing wireless card. In the 24H2 branch, the Windows Connection Manager service, known as WcmSvc, was updated to depend on the WinHTTP Web Proxy Auto-Discovery Service. Because you are running the IoT LTSC Enterprise edition, your system likely has this proxy service disabled by default for security hardening. When the connection manager attempts to load during boot and cannot find this disabled proxy service, it crashes under load and takes your wireless network connection down with it. Restarting the machine forces the services to retry, which can temporarily bypass the timeout and restore the connection.

To permanently fix this, you must remove the proxy dependency from the connection manager using the Registry Editor. Open the Registry Editor with administrator privileges and navigate through the HKEY_LOCAL_MACHINE root folder to SYSTEM, then CurrentControlSet, Services, and locate the WcmSvc folder. Inside this folder, open the DependOnService multi-string value and carefully delete only the line that says WinHttpAutoProxySvc, making sure to leave the other network entries intact.

If your environment restricts editing dependencies, you can alternatively set the proxy service to start manually. Navigate to the WinHttpAutoProxySvc folder within that same Services directory, double-click the Start value, and change its data to 3. This tells Windows to allow the service to trigger manually when the connection manager calls for it, satisfying the requirement without enabling automatic proxy discovery. Once you apply either of these registry adjustments and restart your device, the connection manager will stabilize and your wireless network will stop disconnecting.
