Problem in network Windows 11 24h2

After updating to the new Windows 11h2, some machines experienced network issues with both cable and Wi-Fi. They connect but don’t get network access and receive an IP address starting with 169…, resulting in no internet or network connection. I updated drivers, firmware, and reset the network settings. The machines’ MAC addresses haven’t changed. Does anyone know what could be causing this?

This plus the registry hack fixed the issue for me. Since 24h2 has DNS issues with the internet, I explicitly set it in the IP 4 properties. Internet works great now.

After updating to Windows 11 24H2, this problem appeared. It appears on my computer and on a test virtual machine. I think that the problem is in the DHCP server in my domain. It is version 2012R2 and does not receive updates. The advice above in the thread did not help. After rebooting, you have to manually add the default route, although it arrives correctly from DHCP and is displayed in the routes, but it does not work.

After This update 'Media Tek, Inc. - WLAN - 802.11n Wireless PCI Express Card LAN Adapter' in "Optional updates" which cause the loose of WiFi Module completely ...

and the only solution is to re-install Win 11 24H2.

Please, remove this pilote from "Optional updates"

PC "acer"

Open cmd as admin and typ in the following commands:

netsh winsock reset

and

netsh int ip reset

Restart the computer.

That works for us.

I just tried this. Definitely didn't work.. :( thanks though.
