Hardware drivers dialog?

[Ignasi Cambra]

Hello,
I remember installing the lucid live cd about three weeks ago. Every time the system got started, a dialog appeared telling me to install some proprietary drivers, which actually worked and made my wi-fi adapter active. I installed lucid again yesterday and this dialog doesn't appear anymore. Is it Orca not reading it for us, or is it simply not appearing? Opening the hardware drivers application doesn't provide me with the wireless driver anymore, so I wonder how to get my wireless card to work again...
Thanks!
