Wi-Fi QR Generator

Description: The Wi-Fi QR Generator creates scannable QR codes that let devices connect to a WiFi network without manually entering credentials. It supports two modes: automatic detection of the current wireless network or manual entry of SSID, password, and security type. Generated QR codes can be exported as PDF or image files.

Features:

• Auto-detect mode that reads the current wireless network’s SSID and security type
• Manual entry mode for SSID, password, and encryption type (WEP, WPA/WPA2)
• Support for hidden network configurations
• Export QR codes as downloadable PDF files via jsPDF
• Export QR codes as downloadable image files
• Shell script component (wifi_gen.sh) for command-line network detection

Motivation: Sharing WiFi credentials with guests typically means dictating a long password or writing it down. This tool generates a QR code that any modern smartphone can scan to connect instantly. The auto-detect feature makes it even faster by pulling the current network’s details automatically.

Technologies Used:

• HTML/CSS/JavaScript
• QRCode.js library for QR code generation
• jsPDF library for PDF export
• Shell scripting (Bash) for wireless network detection

Impact: The Wi-Fi QR Generator eliminates the friction of sharing WiFi credentials in homes, offices, and public spaces. Guests can connect by scanning a single QR code instead of typing a complex password.
