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?

I had the same issue after updating to 24H2. Luckily i could recover 23H2 from a system image. The only way i can update to 24H2 and retain the wifi setting (mine disaapeared altogether) is to install the update via a mounted iso of 24H2. the download is avialable from Microsoft.
I believe it is disabled because WPAD is a known security vulnerability. Look at the description on that service and it refers to WPAD. WPAD should have been disabled in any secure configuration via GPO or other secure config management tool. WPAD has not been required for around a decade or more.
Well, Microsoft will release updates today. Do you guys know about the possibility to this issue be addresses on the monthly updates that is about to be released?
Another thing, It is clear that it is a 24H2 issue, how to correctly report this issue to Microsoft? Is there some special channel to follow, engage?
Thank you,
I'm having similar issues but have found that only on a USB-C connection. For example, when connected to a USB-C based docking station or USB-C based network adapter. The issue for us is that the computer isn't getting its DNS information from DHCP. Wireless works fine, USB-A based network adapter works fine. USB-C, not at all. If I manually enter DNS information, I can get out on the internet but if I leave it on DHCP, no DNS information is set.
Corrections - after more testing, this affects USB-A adapters as well. I'm finding that the first port I plug into will get DNS info, but the next port will not. I can move back and forth and DNS will always come to the original port used the very first time, but not to any additional USB ports the adapter is plugged in to.
I am having the DHCP issue on two HP EliteDesk computers using wired Ethernet connection. This is a fresh install of 24H2 from Microsoft ISO. The only workaround is to set static IP address on the network adapter. Using automatic (DHCP) does not work. Both computers worked perfectly fine on Windows 10 and Windows 11 through 23H2.
