I've got a Galaxy Book 4 (NP750XGK-KS2US) that suddenly stopped connecting to the internet. Whenever I try to connect to any Wi-Fi, it shows "No internet, Open" and Chrome gives me the "ERR_NAME_NOT_RESOLVED" error. I've tested several different networks and hotspots, and even tried connecting via USB to my phone, but no luck. Bluetooth is still working just fine. I've already rebooted the device, run the network troubleshooter, and even rolled back a Windows update (KB5066835). Is there anything else I can try?

It sounds like your device might be trying to use custom DNS servers that are no longer reachable. If you've set up your device to point to specific DNS servers like a Pi-Hole, those can get problematic if you switch networks or if the server is down. To fix this, try switching to a more accessible DNS like Cloudflare's `1.1.1.1` or Google's `8.8.8.8`. This way, your device should connect without issues!

I tried changing the DNS to 1.1.1.1 and 8.8.8.8, but unfortunately, it didn't help. What should I try next?
