Hi,

There is no Vista Pro, so I don't know what you upgraded from. If you meant
XP Pro, did you check with Dell support to see if the wireless card is Vista
compatible?

You might try removing/uninstalling the device via device manager, then
reboot and reinstall it with the most recent driver set from the card
manufacturer (not Dell, but the actual maker of the component).
