+You generate a {{{wpa_supplicant.conf}}} file using a tool called wpa_passphrase:
+{{{#!bash
+~# wpa_passphrase MYSSID MYWPAPASSCODE
+network={
+        ssid="MYSSID"
+        #psk="MYWPAPASSCODE"

+}
+}}}
+
+The following steps below can be used to connect to a WPA access point. You will likely need to alter this depending on your OS and distribution.
+
+===== Step 1: Create wpa_supplicant.conf
+For the following example we will use an SSID of 'MYSSID' and a WPA passcode of 'MYWPAPASSCODE' (replace with values your AP is configured with):
+{{{#!bash
+root@ventana:~# wpa_passphrase MYSSID MYWPAPASSCODE > /etc/wpa_supplicant.conf
+}}}
+
+===== Step 2: Start wpa_supplicant
+To start wpa_supplicant manually:
+{{{#!bash
+killall wpa_supplicant # make sure its not already running
+wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B
+}}}
+
+===== Step 3: HDCP
+To obtain DHCP network configuratnoi:
+{{{#!bash
+dhclient wlan0
+}}}
