How to add persistent configuration in /etc/network/interfaces to connect to wireless access point.

Just edit /etc/network/interfaces and write:

auto wlan0
iface wlan0 inet dhcp 
                wpa-ssid {ssid}
                wpa-psk  {password}

A good tool to have installed is the iw command. Run the command 'iw dev' to show the wireless adapter information.

#####

To have a non persistent configuration use the following commands.

//This creates a configuration file for the wifi
sudo wpa_passphrase WLAN_NAME WLAN_PASSWORD > /etc/wpa_supplicant.conf

//Optional command to run to see drivers
wpa_supplicant

//Run command with config file and driver as options
wpa_supplicant -i wlp3s0 -c /etc/wpa_supplicant.conf -D wext

NOTE: This is best used on a machine with network manager not installed as they will compete.
This is also only for wireless access point using WPA authentication, which is most nowadays.
