WPA security / 9.04 / Broadcom Card: Connection Difficulties

[Klemts]

Hey Folks,

Perhaps someone can point me in the right direction.

My Presario v2000 laptop will detect wireless networks, but is unable to connect to any which use WPA security.
It will connect to WEP and unsecured, but stalls (indefinitely) while validating the passphrase with WPA security.
Under Windows, everything, including this particular WPA network, works as expected; no interference. Under Ubuntu; otherwise.

Here are a few specs:
Linksys wireless router; model WRT160Nv2.
Compaq Presario v2000
Wireless Card - BCM4318 (rev02)
Ndiswrapper has been working as expected since 8.04
Current Version: 9.04

Thanks.
