To fix a Secured, No Internet Connection, start by restarting your router, modem, and the affected device, as this can often resolve temporary network glitches. If the problem persists, try forgetting and reconnecting to the Wi-Fi network to reset the connection. Updating your network drivers can also help, as outdated drivers might cause connectivity issues. Additionally, resetting the TCP/IP stack and flushing the DNS via Command Prompt can resolve configuration errors. Finally, if you have firewall or antivirus software, consider temporarily disabling it to check if it's blocking the connection.
