This video tutorial addresses the issue of connecting a Raspberry Pi to a new Wi-Fi network when the existing configuration is inaccessible. It guides users through preparing the SD card, creating a WPA supplicant file, and configuring the Raspberry Pi to connect to a new network without losing existing data. The tutorial also covers verifying the connection and updating the IP address using tools like Angry IP Scanner and VNC.

What is the main issue addressed in the video regarding Raspberry Pi and Wi-Fi networks?

• Issues with VNC software

• Problems with Raspberry Pi hardware

• Difficulty in installing Raspberry Pi OS

• Inability to connect to a new Wi-Fi network without losing data

What is the first step in preparing the SD card for a new Wi-Fi network?
