Could it be a conflict, I also have a broadcom card and I had to 
blacklist so that the "free" driver and the propriatary does not both 
try to control the card.

In my  /etc/modprobe.d/blacklist.conf I have these 3 lines added:
blacklist bcma
blacklist brcmsmac
blacklist brcmutil

I had to add this in 11.10 already as that was then ubuntu for whatever 
reason did not automagically remove the free driver when you install the 
broadcom driver
