A method to check internet connectivity is by opening a specific application that requires an internet connection. WhatsApp is an example of such an application. When you launch WhatsApp, it immediately attempts to establish a connection with its servers to synchronize your chats and display any new messages. If you can see your chat conversations and receive real-time updates, it indicates that your device is connected to the internet. See the pic below

Connecting to Wi-Fi is the initial step, followed by establishing an internet connection.

However, it's important to note that connecting to Wi-Fi does not automatically guarantee an internet connection. If you are unable to connect to Wi-Fi, the issue may stem from settings on your iPhone or the router/modem.

On the other hand, if you are unable to establish an internet connection despite being connected to Wi-Fi, the problem is likely related to the settings on your router/modem. In such cases, it is advisable to promptly contact your Internet Service Provider (ISP) for assistance.

Update your software: Make sure that both your iPhone and Mac are running the latest software versions. On your iPhone, go to Settings > General > Software Update, and on your Mac, go to the Apple menu > System Preferences > Software Update.
