Before you start
- Check whether other devices can get online. If they cannot, restart the router/modem before changing Windows.
- If only one website or app fails, the problem may be that service rather than Windows.
Check Wi‑Fi and Airplane mode
Open Quick Settings with Windows + A. Make sure Wi‑Fi is on and Airplane mode is off. Select your network and confirm it shows Connected.
Forget and reconnect
Go to Settings > Network & internet > Wi‑Fi > Manage known networks. Select the affected network > Forget, then reconnect from the Wi‑Fi list and enter the password again.
Restart the network equipment
If other devices are also affected, unplug the modem/router from power, wait at least 30 seconds, reconnect the modem first, then the router, and allow them to finish starting before testing again.
Run the Network and Internet troubleshooter
Open the Get Help app and run the Network and Internet troubleshooter. Microsoft recommends this as the first automated Windows 11 diagnostic.
Install Windows and driver updates
Go to Settings > Windows Update > Check for updates. Also check Settings > Windows Update > Advanced options > Optional updates for network-driver updates.
Use Network reset only as a last step
Go to Settings > Network & internet > Advanced network settings > Network reset > Reset now > Yes. Windows removes and reinstalls network adapters and resets their settings. VPN clients and virtual switches may need setting up again afterward.
