I've hit a breakthrough on this.

Once I removed the proprietary 'Broadcom STA ...' driver this issue was resolved.

So this isn't about kernels. And I did confirm this by testing some kernels.

This is about the presence of the proprietary driver that breaks support for the card.

Once I uninstalled it using the 'Software Sources' I had my interface back.

So there are two issues here. One is that the proprietary driver doesn't work. At least not in quantal for this card.

The other issue is that this proprietary driver was installed automatically in one of the quantal updates at one point. I didn't call for it, IIRC. And it would make sense that if I would have installed it by myself I would have remembered that I had and would have reverted back once I had no WiFi.

Thanks,
Shahar
