[ndiswrapper] Realtek RTL8187B cannot connect to WPA/WPA2 network

Binary package hint: network-manager

I'm using ndiswrapper with the vendors driver, and I'm trying to use my usb wireless card :
;; net8187b.inf
;;
;; Realtek RTL8187B Wireless 802.11g 54Mbps USB 2.0 Network Adapter

The access point is configured this way:
WPA: WPA-PSK (No Server)
WPA mode: WPA/WPA2 mixed mode
Encryption technique: AUTO for WPA, AES for WPA2

I enter my ESSID chose "WPA personal" and use my Pre-shared Key (PSK) on nm-applet
It keeps asking the password and never connects. I also tried with "WPA2 personal" and other options and they all fail.

Is there a way to connect on WPA2 with this configuration on access point???
I'm sure I typed the (PSK) on the right place with the right value... did i had to type the generated key???
I tryed without the encriptation and the wireless card worked just fine so in think ndiswrapper is working ok.

ps:
I looked the windows configuration and it says its connected through WPA2, (AP says wpa/wpa2 mixed mode).
When I did some manual configuration through ifconfig, iwconfig the network manager lost the wireless networks options like they vanished ...
It became slower too, when trying to apply changes I have to wait several minutes

Im using Ubuntu Hard 8.04 beta
