Everything you posted as dmesg output came from your firewall and involved eth0, 
not your wireless card. As such, that output tells us nothing.

A BCM4306 (14e4:4320) with Rev 3 should use b43, not b43legacy. You could tell 
that by looking at the output of dmesg immediately after running the following 
two commands:

sudo /sbin/modprobe -rv b43
sudo /sbin/modprobe -v b43

A BCM4306 is pretty simple. The one I use is a PCMCIA device with two LEDs. One 
is steady to indicate power, and the other blinks when there is traffic. I have 
no idea what configuration you have, or what the LEDs indicate.

When the device stopped working, what was changed on your system? Was there a 
new kernel, or did some other software get changed? Perhaps your device 
malfunctioned.
