Problem in network Windows 11 24h2

Hello,

Same here, no network after upgrading to 24H2. But for us it seems that the problem is not DHCP: network adapters are disabled in control panel, but not in device manager.

Unable to enable it. It says enabled but returns back to disable immediately. If it stays for a while, it goes unable as soon as I connect an ethernet cable, or seconds after that.

Wi-Fi button in quick setting bar is totally absent.

All drivers and bios are up to date.

Several machines are concerned, HP notebook and HP desktop mini. We had to roll back to 23H2 to get back a functional network. Surprisingly, every machines are not concerned for now, even if same model...

Also, big problems with SSO in Citrix have been seen, needing a rollback to. And some machines got display problems, with persistent windows on screen even though they're really closed.

It's been a long time since an update was so catastrophic. Too bad it wasn't delayed for the wsus channel...

Not hurry to go back to work on Monday as there will surely be other machines to restore. For example on my machine, problems occured after a reboot, not right after upgrading.

Roll back to 23H2 solves the problems. For now we blocked all 24H2 upgrade!

Hi, I had exactly the same issue.

Few users at home that has Vivo as ISP provider are not capable to receive the IP from the VIVO router. Fixing the IP works...

The impression that I have is that the Vivo router is not "compatible" with the Windows 24H2. I mean, it seems that the Windows 24H2 is not capable to "understand" the IP provided by the router..... it is clear that it is a DHCP issue...

The issue happens either with Cable (wired) or WiFi (wireless) connection. So it is not a driver issue or network card model.....

After some more messing around I think this time I got it.

The WLAN AutoConfig service has a dependency on Windows Connection Manager.

Windows Connection Manager has a dependency on the WinHTTP Web Proxy Auto-Discovery Service.

I went to the registry and removed the dependencies on the WinHTTP Web Proxy Auto-Discovery Service. Rebooted a few times and success.

I base this upon the 23H2 services NOT having the dependencies on the WinHTTP Web PRoxy Auto-Discovery Service.

Here is the change I made in the Registry: NOTE THIS IS FROM MEMORY

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wcmsvc

DependOnService = REG_MULTI_SZ:RpcSs NSI

I Removed the 3rd Service listed there which should be the WinHTTPAutoProxySvc

This has seemed to resolve my issues for now.

The fix for no Wifi:

Open Regedit as admin

Look for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wcmsvc

Open DependOnService and remove WinHTTP Web Proxy Auto-Discovery Services.

Click OK and reboot.

I tested several computers yesterday and restored them to full functionality by simply removing the winhttpautoproxysvc service from dependency.

That service should be disabled because it is insecure.

The exact fix I found to work 100% of the time is:

HKLM\System\CurrentControlSet\Services\WcmSvc

In the root of the key, look for value DependOnService.

Edit it.

Remove WinHTTPAutoProxySvc

Save.

Start Windows Connection Manager service. Start WLAN AutoConfig service.

Then location services complains about being off. Go into Settings, Location. Turn OFF the notifications about location services being off.
