ctrl_interface_group=wheel

network={
        ssid="blog.namran.net"
        key_mgmt=WPA-PSK
        proto=WPA
        pairwise=TKIP
        group=TKIP

}

then run the folllowing
assume if your wireless device is bind to eth1

wpa_supplicant -B -dd -i eth1 -c /etc/wpa_supplicant/wpa_supplicant.conf 

then just DHCP client :

/sbin/dhclient eth1

or

ifup eth1

it shall then request for IP address and all.
