What can be the reason that Windows XP does not show WPA-encrypted wireless networks?

The laptop I have problems with is an older model (Toshiba Satellite Pro 6100) with Windows XP SP3 on it, fresh install.

The wireless network card in it is an Agere product that lists as "Toshiba Wireless LAN Mini PCI Card".

The networks showed up perfectly before I first tried to connect to one (it was set to WPA2). The connection failed (the card supports WPA only), then something must have happend and Windows hides these networks now.

A manually configured WPA setup via Windows' own wizard works, I'm using it right now. The network just won't show up in the list of available network on its own.

I suspect that XP incorrectly set a flag somewhere that this network card does not support WPA. Is there such a flag, and if so, how can I change it back?
