Thanks Cyrnel, I think the end is in sight.
Unfortunately, I've found myself back at square one. After installing the driver, I was able to activate the card and even recognize the network.
But for some reason I couldn't enter the WEP key in the field. It was open (not greyed out) and I could place the cursor there, but was unable to type.
I clicked okay and I seemed to be online. But when I tried to open Explorer, my homepage wouldn't load. Absentmindedly, I clicked on the "Detect Network Connections" link on the default error page.
The computer immediately shutdown.
I've uninstalled and reinstalled the driver and removed the other network adapter devices through the device manager to no effect.
I'm not sure anymore what needs to be inplace for the card to trigger the new hardware wizard rather than a shutdown.
