Apps don’t dettect my wifi and might made it worse

Today I turned on my computer expecting to play games as usual (Windows 11) and certain applications like Microsoft Store and others wouldn't load, and the message "connection expired" appeared. The same applies to pages that are not from Google, such as a bookstore website.

I tried to find information and ended up asking DeepSeek for help. I changed the DNS and then with the console I I reset the IP and ran some commands like ntesh winsock and more. I understand they're for resetting the connection, but I don't really know what's wrong.

Now they simply don't detect my Wi-Fi even though I can browse without any problems. And yes, it's only my computer; other ones that use the same Wi-Fi work fine.

Please help
