Trouble connecting to a Cisco LEAP-enabled newtork

Since Windows Vista has no native ability to use the Cisco LEAP protocol,
which my school requires for access to its campus-wide WiFi network, I was
forced to turn to third-party software, as I did while running Windows XP
Professional, SP2. I use a Cisco AiroNet 350 series PCMCIA card for access.
Since I have a ThinkPad T23, I loaded the latest versions of IBM’s
AccessConnections package, which supports LEAP, and the Cisco AiroNet Client
Utility.

Neither of these packages worked under Vista! AccessConnections was able to
load and operate, but had no apparent affect on the wireless connection and
could not “power on� the wireless radio. The AiroNet client utility worked
only in compatibility mode for Windows 98/ME and even then brought up a
message proclaiming that “No client adapters were found.�

With that, there was no way I could connect to my campus’s network. This
would be a BIG post-platform-migration problem for any of the thousands of UA
students who are using Cisco’s AiroNet 350 Series PC Cards to access the
internet while on campus.

The card DOES connect to open, non-secure wireless networks with Vista's
network management utilities.

Our campus network is made of the following:

580 Cisco Model 350s

400+ Cisco 1200 Series APs upgraded to wireless B/G
