Lately I've seen more firmware issues with the "older" Broadcoms (like the 4311 & 4312). It seems to me that the 10.xx versions of Ubuntu are having a difficult time with some of the "older" firmware recently- possibly the kernel has been "tweaked" in this vicinity.
Also, have you tried any of the "proprietary"
hardware drivers like the
Broadcom STA driver? The
Broadcom 4321 in my HP laptop seems to prefer the "STA" driver, but it also worked fine with the "b43" proprietary hardware driver too from what I remember from long ago (somewhere around Ubuntu 8.10-9.04).
