Wifi Code allows you to generate a QR code for your Wifi network.
You want to share your wifi network:
1) Enter the name of your network (SSID)
2) Enter your network password (if you have one)
3) Select your type of network security (WPA default, WEP)

This is by far the easiest and most convenient way to connect to a Wifi network.
