Internet works on phone but not on the PC

Because your phone works on the same Wi-Fi, the internet service and router are probably available; the fault is more likely in the PC’s IP, DNS, proxy, VPN, or network-adapter configuration. First forget the Wi-Fi network in Settings, reconnect with the password, and restart the PC. Run the Network and Internet troubleshooter in Get Help. Then open Command Prompt as administrator and run ipconfig /release, ipconfig /renew, and ipconfig /flushdns in that order. Check Settings > Network & internet > Proxy and disable any manual proxy you did not intentionally configure; disconnect a VPN temporarily as a test. Try one trusted site and record the exact browser error. If Ethernet works, focus on the Wi-Fi adapter and install its current driver. If neither connection works, use Network reset only as the final step because it removes network adapters and requires VPN and Wi-Fi settings to be configured again.
