Fix Windows Connected to Wi-Fi with No Internet Access

Resolve No Internet connection issues on Windows while connected to Wi-Fi. Follow these steps to reset your network stack and clear DNS settings.

1. Run the Windows Network Troubleshooter. Open the Settings app using Win + I. Navigate to System > Troubleshoot > Other troubleshooters. Locate Network Adapter and select Run to initiate the automated diagnostic tool.
2. Reset the TCP/IP Stack. Search for cmd in the taskbar, right-click Command Prompt, and select Run as administrator. Execute the command 'netsh int ip reset' and press Enter to reset the Internet Protocol stack.
3. Flush and Renew DNS. Within the administrator Command Prompt, type 'ipconfig /flushdns' and press Enter. Follow this with 'ipconfig /release' and then 'ipconfig /renew' to force your network adapter to request a fresh IP configuration from your router.
4. Assign Public DNS Servers. Press Win + R, type 'ncpa.cpl', and press Enter. Right-click your Wi-Fi adapter, select Properties, and double-click Internet Protocol Version 4 (TCP/IPv4). Select 'Use the following DNS server addresses' and enter 8.8.8.8 for the Preferred and 8.8.4.4 for the Alternate DNS server.
5. Restart Network Hardware. Power cycle your router by disconnecting it from the power source for 30 seconds. Reconnect the power and wait until the indicator lights reflect a stable connection before restarting your Windows machine.
