Experiencing 'No Internet Access' on Wi-Fi can be frustrating, but there are several troubleshooting steps to resolve the issue:
Check Wi-Fi Connection: Ensure your device is connected to the correct Wi-Fi network. Verify the Wi-Fi icon in the system tray or settings to confirm the connection.
Restart Router and Modem: Power off your router and modem, wait for about 10 seconds, and then turn them back on. This can often refresh the connection and resolve connectivity issues.
Check Other Devices: If other devices are also unable to connect, the issue may be with the router. Restarting it or contacting your internet service provider may be necessary.
Forget and Reconnect: Forget the Wi-Fi network on your device, then reconnect by entering the password. This can establish a fresh connection.
Update Network Drivers: Ensure your device's network drivers are up to date. Visit the manufacturer's website or use the device manager to update the drivers.
Disable and Enable Wi-Fi: Turn off Wi-Fi on your device, wait a few seconds, and then re-enable it. This can trigger a reconnection to the network.
Check for Interference: Other electronic devices or neighboring Wi-Fi networks can cause interference. Change the Wi-Fi channel on your router to minimize interference.
Reset Network Settings: On your device, reset network settings to default. This may involve resetting Wi-Fi passwords and network preferences.

If these steps don't resolve the issue, contacting your internet service provider or seeking technical support may be necessary to address potential network problems.
