My laptop shows connected to WiFi with full signal but says No Internet Access. All other devices work fine on the same network.
This means your laptop has a WiFi connection to the router but cannot reach the internet. The most effective fix is a network reset. First try the quick method: open Command Prompt as Administrator and run these commands one at a time — netsh winsock reset, then netsh int ip reset, then ipconfig /flushdns, then ipconfig /release, then ipconfig /renew. Restart your computer after running all five. If that does not work, go to Settings, then Network & Internet, then Advanced Network Settings, then Network Reset at the bottom. Click Reset Now — this removes all network adapters and reinstalls them with default settings. You will need to reconnect to your WiFi afterward. Another common cause is incorrect DNS settings. Go to your WiFi adapter properties, double-click Internet Protocol Version 4, and make sure Obtain DNS server address automatically is selected, or manually set DNS to 8.8.8.8 and 8.8.4.4 (Google's DNS servers). A corrupted VPN or proxy configuration can also cause this — check Settings, Network & Internet, Proxy and make sure Use a proxy server is turned off unless you intentionally set one up.
