doesn't get assigned a new ip address after startup - windows 11 bug

I have multiple lenovo devices isn't able to connection to internet after bootup.

There's nothing wrong with the network, and what seems to solve the issues temporarily is:

  • run a ipconfig release & renew
  • reboot adapter

This issue seems to have appeared after recent windows updates (24h2), and I want to know some further details why it hasn't been resolved yet.

    I can see my users request dhcp server multiple times -  like over 500 requests - so must be something with network adapter that doesn't receive correctly from dhcp - thoughts? MrMiken​  Jie-Aosi​

    Microsoft updates sometimes introduce regressions or bugs that take time to identify and fix. Specific hardware (Lenovo devices) may have driver or firmware incompatibilities that complicate the issue.

      absolutely, but I find particular annoying is Windows hasn't been transparent on this particalular issue which I suspect has happened after 24h2 - it's up to us to somehow find an alternative solution

    ​​Reset TCP/IP stack. Open Command Prompt as Administrator and run:

    netsh int ip reset
netsh winsock reset
ipconfig /flushdns

      thank you so much MrMiken​ 

      hmm, it didn't really resolve the main issue of what I suspect is not retrieving IP address from dhcp correctly during bootup, but short term yes.  

      Then I might as well run ipconfig /release ipconfig /renew
