[AuckLUG] Ubuntu 7.04, wireless card and WPA-PSK?

When doing lsmod, the only thing that i can see that appears relevant is
an rt61 module. My card is rt2561st. Should I have an rt2500 module? I
tried the config below and still do not have success.

My machine also insists that the card is ra1, not ra0, despite there being
no other wireless card. I have an onboard ethernet interface that does not
work (sis968 Gigabit according to the manual), a pci ethernet card which
is being recognised as eth0, and of course lo.
 I set up the config below for ra1. iwconfig now recognises the correct
SSID, but shows no sign of a WPAPSK password being used and network
manager now does not even recognise a wireless network. Should the
password be the encoded version?

Thanks
Ken
