[iBook] WPA-PSK

[Wai Lee]

I recently upgraded our wireless router to a Netgear WGR614.  It offers 
a WPA-PSK encryption option.  I have managed to get a couple of WIN XP 
laptops connected ok, but when I try to get our ibook to sign on using 
WPA Personal security, it says "The wireless network ... does not 
support the requested encryption method".  Does anyone know what's up?  
I can't seem to find any other option on the ibook resembles WPA.
