Just generate, scan, and connect! Couldn't be easier! If you're rooted, a QR code will be generated as soon as you open the app, or simply select a network and a QR code will be created!

Steps:
1) Select a network Android remembered or you saved.
2) Show another person the QR or save/send it, using email, Dropbox, printing it, etc.

or

1) Enter your network name (SSID)
2) Enter your network password (if you have one)
3) Select your network security type (WPA, WEP, or Open)
4) Show another person the QR or save/send it, using email, Dropbox, printing it, etc.

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