Apps Connect to Wifi.

[yuxuantim]

I realize this question has probably been asked a thousand times. I am a beginner programmer, and I need help learning. I have read the documentation of thus area, but it is a little hard to understand as a beginner. I also have looked at other questions like this. My question is: A) Hiw do I search wifi and find info about config. B) How do I connect to one after getting password. (Specifically, WPA2). Thank you for your time. Please remember that I am a beginner.
