Test the same Wi-Fi on another device first: if it also has no internet, restart the modem and router or contact the ISP; if only this Windows 11 PC is affected, run the Network and Internet troubleshooter, reconnect to Wi-Fi, renew its IP address, and check an unintended manual proxy. Use Network reset only last.
If only this PC is affected, make sure you know the Wi-Fi password. Open Settings > Network & internet > Wi-Fi > Manage known networks, select the network, and choose Forget. Return to available networks, select it, choose Connect, and enter the password.

Find the failing side
Open two unrelated sites on another phone or PC using the same Wi-Fi, then test this PC on another network if one is available. If every device fails, investigate the router or ISP. If only this PC fails, continue with the Windows checks.
3
Run Windows diagnostics
Open Get Help and run the Network and Internet troubleshooter. Apply only the recommendation that matches its result, then test two unrelated fresh webpages.
4
Restart equipment for a network-wide outage
If other devices also fail, warn users that the connection will drop. Unplug the router and modem for 30 seconds, reconnect the modem and wait for its lights to settle, then reconnect the router and test again.
5
Renew this PC's address
Search for Command Prompt, choose Run as administrator, then Yes. Run ipconfig /release, ipconfig /renew, and ipconfig /flushdns, then test again.
6
Check an unintended manual proxy
Open Settings > Network & internet > Proxy. If you personally enabled a manual proxy and no longer need it, open Set up and turn Use a proxy server off. On a managed network, ask IT and do not disable required scripts or VPN settings.
7
Use Network reset last
Open Settings > Network & internet > Advanced network settings > Network reset > Reset now > Yes. Windows removes and reinstalls adapters; VPN clients or virtual switches may need setup again, and known networks may return as Public. Success means the status no longer says No Internet and two unrelated fresh sites load.
Video walkthrough
If it does not work
If only one site or app fails while others load, troubleshoot that service or app instead of resetting Windows networking.
If ipconfig shows 169.254.x.x, the PC did not receive an address from the router; check DHCP or ask the network administrator.
If every device on the Wi-Fi fails, focus on the router or ISP. If this PC fails on every Wi-Fi network, use the PC maker's adapter driver.
On a managed work or school network, contact IT before changing proxy, DNS, VPN, or adapter settings.
