I see - a fresh install and not really an upgrade, technically. And it 
is is of course always supported.

OK, that is a Broadcom card which should be supported (and actually you 
wrote that it worked with 10.04). IIRC, there are several Broadcom 
drivers and maybe the wrong one was automatically selected for some 
reason, or perhaps the firmware is missing. However I can't help you 
further because I'm not familiar with Broadcom chipsets. Hopefully 
someone else on this list has an idea what to do.
