I've spend a couple of hours now trying to get my wifi card working. I moved the PCI-card from a working machine to a new one. Both running Ubuntu 12.04. The card worked fine in the first machine but now it cannot find any wireless networks. I'm using wl driver as it was told to be working with BCM4321 chipset. And I used this page as a guide for installing: https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#A12.04_.28Precise_Pangolin.29_-12.10.28Quantal_Quetzal.29
I hope somebody can give an advice to help my misery :) Details below.
dmesg (BCM4329 looks suspicious as the chipset should be BCM4321):

lshw (Is driver=wl0 OK?):

lsmod (The driver doesn't really communicate with the kernel right?):

The changes I made to /etc/modprobe.d/blacklist.conf (added the 3 last ones):
# replaced by b43 and ssb. blacklist bcm43xx blacklist brcmsmac blacklist bcma blacklist b43
