Connect to Network without assign IP address

[Carlos Patricio Amigo Haering]

What I'm doing wrong ? wlan0 doesn't have assigned IP. I have to set 
special parameter to the network if i'm not using IP?

# service network-manager stop
# cat /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant

network={
	ssid="OF"
	bssid=20:aa:4b:54:f1:ce
	key_mgmt=WPA-PSK
	group=CCMP
	pairwise=CCMP
	proto=RSN
	psk="*****"
}

# ifconfig wlan0
wlan0     Link encap:Ethernet  direcci?nHW 00:1b:77:15:7d:d1
           Direcci?n inet6: fe80::21b:77ff:fe15:7dd1/64 Alcance:Enlace
