- Try the same network on a phone. If the phone also opens nothing, restart the router: unplug it, wait thirty seconds, and plug it back in. If it stays dead, the fault is the ISP or the router.
- If only the computer fails, forget the Wi-Fi network and join it again. Check the password.
- In PowerShell run
ipconfig /flushdns. If a site opens by its numeric address and not by name, set the adapter DNS to1.1.1.1and1.0.0.1as a test. - Turn the phone into a hotspot and join it from the computer. If the web returns, the home Wi-Fi is the problem. If it still fails, the problem is that computer.
Do not install a network optimizer. The phone-hotspot test already shows which side is broken.
