I had the same problem too.  I could connect to an unencrypted, but not 
to an WPA network.  I ended up removing network manager and using 
wpa_supplicant.

Here is my /etc/wpa_supplicant/wpa_psk.conf
------ BEGIN ---------------
ap_scan=2
network={
             scan_ssid=0
             proto=WPA
             key_mgmt=WPA-PSK
             pairwise=TKIP
             group=TKIP
             ssid="My Router SSID"
             psk="My Password"
             }
----- END -------------

And here's my /etc/network/interfaces
----- BEGIN --------
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo wlan0
iface lo inet loopback

iface wlan0 inet dhcp
#       address 192.168.1.30
#       netmask 255.255.255.0
         wireless-essid children
         gateway 192.168.1.1
         pre-up wpa_supplicant -B -Dwext -iwlan0 -c 
/etc/wpa_supplicant/wpa_psk.conf
         post-down killall -q wpa_supplicant
----- END -------------

This gets me online as soon as I boot up.  At any other time, I can 
bring it up with 'sudo ifup wlan0'.
