This flowchart shows the step-by-step process a device follows to connect to a Wi-Fi network and then access the internet, including scanning, selecting, authenticating, and obtaining an IP address.

Step-by-Step Trace - 10 Steps

Step 1: Device scans for available Wi-Fi networks nearby.

Step 2: Check if desired network 'HomeWiFi' is found.

Step 3: Device selects 'HomeWiFi' to connect.

Step 4: Device sends connection request with password.

Step 5: Check if password is correct.

Step 6: Device connects to Wi-Fi network.

Step 7: Device requests an IP address from the router.

Step 8: Device receives IP address from router.

Step 9: Device sends request to access the internet.

Step 10: Device is connected to the internet successfully.
