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?

    If there is one I haven't found it yet and I've tried like 5 times. I'm done for now.

    At your home, you are using your Internet Service Provider's DNS-servers to do DNS-queries, e.g., "find IP-address for the name www.ibm.com". 

    At work, you probably are using either a different I.S.P., or your employer's network is using some other DNS-servers, maybe to "filter" DNS-queries to block access to some NSFW web-servers by the employer's employees.

    So, that's the difference, and changing DNS-servers is a good solution for everybody having the issue.

    By the way, who is your I.S.P. ? I am wondering which ISP(s) have the issue.

    .

    I mainly use my ISPs DNS servers (automatic settings) although I have tried both Google & Cloudflare at various times in the past.

    I'm 21 with 52 years experience 😂 so don't work any more

    Only had this problem with the release of 24H2, all previous versions of Win 11 gave no problems, but as with most things nowadays, fix one problem and create 10 more.

    ISP is Community Fibre in London, UK utilising the Linksys Velop WHW0303 Triband mesh system

    Hey, is there anyone who could try this solution on their 24H2? I'm back on 23H2 more than a week without problems...

    I've just found this:

    I added the following to registry: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters TcpTimedWaitDelay: Set it to 30000 (30 seconds) KeepAliveTime: set it to 60000 (1 minute) KeepAliveInterval: Set it to 1000 (1 second) I also downloaded and ran TCPOptimizer and ran that: speedguide.net/downloads.php Screenshots on this forum for TCP settings: speedguide.net/forums/… Seems to be working so far. I will update if anything changes.
