Problem in network Windows 11 24h2

I think I've tried all the options. I've now reset my PC to 23H2.

Both systems aren't using Wi-Fi direct to router and show the same behavior no matter what I try, so I'm going back to 23H2 until MS gets its life together and gives an OS that doesn't require that you fix everything. I do appreciate your response.

For me, the solution was to remove DHCP Option 121, which I no longer needed. All our Win 11 24H2 laptops now connect to our Office Wi-Fi. Check your DHCP server and see if you can remove any of the DHCP options. I read someone had an issue with DHCP Option 43. With so much noise coming from the community, I thought Microsoft would have been a bit more proactive, all seems quiet on their end. Hope this helps someone. Good luck!

My problem has been solved in the meantime. First I discovered that when checking the network settings, instead of only one, there opened two tabs - first one saying that there were two network connections, one private (as always) and the second unidentified. Proceeding, there was the second tableau saying that it was a private network. But the unidentified network displayed in the first case used exactly the same adaptor and the same internet connection. I searched for a solution in the internet, and this seems to be a frequent error ocurring after an update, also in previous Windows versions. I learne that a network reset would solve the problem. As I searched for the solution in German language sites, I can't reproduce the advice they gave. I therefore looked up if there are English language sites with similar proposals. Here is one of them:

The proceeding that I followed was using the command prompt with administor privileges. And if I remember correctly, it was the second of the commands proposed that I applied, and with success. When the operation was completed, he unidentified network had disappeared completely. I had full access to my laptop in my network. But still I couldn't open my NAS. It was displayed, but I had acess only to its control panel, not to the data folders. I called the support of Western Digital, the manufacturer, and the technician there had a solution. With immense patience, he guided me via co-browsing through the process of reintegrating the NAS in the network by adressing it not as usual but using its IP address. Now everything is working as it should.
