Hello, thank you for your feedback. I understand your concerns with your device connecting to Wi-Fi without internet and I will be more than happy to take a look into this with you.
Sometimes Wi-Fi problems are caused by simple network issues. Other times, you may need to take additional steps on your phone or tablet to ensure your Wi-Fi connection is stable, such as re-adding the connection or assigning a static IP address.
Make sure you have the correct password for the network. Sometimes an incorrect password will make it appear as though you are connected but will not provide any access.
Navigate to Settings, and then tap Connections. Tap Wi-Fi, and then tap the Settings icon next to your desired network. Tap Forget, and then try reconnecting to the network.
Restarting your router and devices can help fix simple connection errors.
If you are unable to access the internet after you have rebooted the Wi-Fi router, please contact the Internet Service Provider for further troubleshooting.
