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?

How are you measuring the "slowness" ?
After restarting, open the Windows Task Manager,
or run the "resmon.exe" Resource Manager.
It could be Windows Update checking for updates,
monopolizing your CPU & your Internet.
It could be Disk Defragmenter, monopolizing your disk-drive.
Result: doesnt work for me
The only workaround that I could apply is Workaround 2: registry hack, because I already have a static IP for my machine and DNS already setted.
Rebooted my PC: internet connection really slow or absent.
Rebooted 2 times and I'm here to write this post.
I have found the solution here:
It works.
Another crazy problem with 24H2 is: DHCP Server on Hyper-V Virtual machines does not work at all if host OS is Windows 11 24H2! Still no solution presents.
Doesn't work. Tried to disable and re enable network adapter without reboot my PC, but Internet remain slow. I must necessarily reboot completely my PC to have again a decent Internet speed connection
Maybe it works for me because of my connection 1Gb symmetrical Full Fibre, never had a speed problem since getting it.
If it would not connect, then just click the "Skip" button on that "networking" page, to move on to the next screen.
Eventually, when Windows is fully installed, you can complete the "network setup".
So, while using a "hot-spot" on your smart-phone will work, you can finish installing Windows without having any network access during the late steps of the installation process.
