Problem in network Windows 11 24h2

...

Here is what I found though it does appear to be a timing problem with the Network Adaptor not finding the connection that is causing it, if after resuming or a Restart and it comes up with No Internet, disabling the adaptor and waiting approx 30-40 seconds then re-enabling it, it finds the connection, there is the odd occasion I have to use the Diagnose option and Restart the Adaptor to get it to work.

I've read this also from another user, so I decided to retry and actually this works, it's not necessary reboot completely pc, but could to not work immediatly at the first attempt, could be necessary retry more times and however 30 seconds are too much. It Works also restarting network adapter after 10 seconds.

Agreed, trouble is it is not constant, that's why I suggested 30-40, I have now set up a Command Prompt batch file to do this with a shortcut to make the batch file run as Administrator, much easier.

netsh interface set interface “Ethernet” disable

TIMEOUT /T 30 /NOBREAK

netsh interface set interface “Ethernet” enable

Check what your interface is called in " "

The update so awaited is arrived, it's named KB5050094 and is possible to download it just now without wait 11 february, but it hasn't solved the bug! I think my Windows 11 is corrupted and I must format completely my PC but now I will disable windows Update because I don't trust Microsoft anymore

Cara, como mencionei no post acima.

Resolvi esse problema desativando a opção 43 no escopo DHCP.

É provável que o roteador da VIVO esteja com essa opção no DHCP Server habilitada. Tenta verificar se tem opções de escopo habilitado no DHCP Server do roteador.

To be clear. Our computers don't even have Wifi and/or Ethernet icons so impossible to contact any DHCP server. When you click on network icon we have no wifi available and no SSID available. So is not a DHCP problem.

A interface do roteador VIVO é muito simplificada.. só permite habilitar ou desabilitar o DHCP, definir a faixa de IP's a serem usados e "fixar" IP's para uma lista de MAC ADDRESS. Estranho que foi algo introduzido no 24H2, porque antes de atualizar, estava tudo funcionando muito bem.

But this is the problem, how to request the people who is working at home to access their ISP router, and deactivate the option?

I see that this solution will work for a few people, but not for a large group......

It was working perfectly before the upgrade, so there is something different in the 24H2 that must be fixed..
