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 have a similar issue. The original 24H2 build worked fine, but the October cumulative caused wireless network issues to appear. After the cumulative update, WiFi is totally missing from the system tray (but bluetooth still appears) and Wi-Fi doesn't work. Ethernet does still work via DHCP. Running IPconfig from the command prompt reveals 169. address and no connections can be made with WiFi.

    Same issue with a gigabyte z690 UD DDR4 motherboard and realtek 2.5Gb ethernet.

    Approximately each 24 hours when I turn on my PC i have link up but no valid IP (only ip in 169, default ip when no dhcp). I I thought it was my DHCP server but no, each other computer get IP address.

    With wireshark i can see traffic on network.

    i have try a lot of things like reinstall windows, change drivers, change switch, change DHCP server.

    I have found a workaround, i turn off my switch, wait 15s and turn on my switch. Windows detect link down/up and network is back.

    For the moment i downgrade to 23h2, waiting for a real patch from MS.
