wpa_supplicant -B -D wext -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf
iw wlan0 link
dhclient wlan0

or automate by add this to /etc/network.interfaces

allow-hotplug wlan0

Console connection

Using this console cable, you can enable remote access from your laptop.
From osx, you just type as,

sudo screen /dev/cu.usbserial 115200

GPIO order is,
Green, White, Black, blank, Red.... Careful not to connect Red if power comes from another source as well.
