This flowchart starts by checking if Wi-Fi is available. If not, it shows a message and ends.

If Wi-Fi is available, the user is asked to enter the password. If the password is wrong, a message is shown and the process ends.

If the password is correct, the device connects to the router.

Next, it checks if the internet is accessible. If yes, it shows a 'Connected' message; if no, it shows 'No internet' message.

Finally, the flow ends after showing the connection status.

Variations - 2 Challenges

[intermediate] Draw a flowchart for connecting a device to a Wi-Fi network that includes retrying password entry up to 3 times before stopping.

[advanced] Draw a flowchart for a device that can choose between multiple Wi-Fi networks, connect to the strongest one, and verify internet access.
