[Bug 42067] Re: not working on Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03)

[jason chan]

You are using a bcm4306?  Usually when I sudo iwlist eth1 scan and get
no results, then that means my wireless was disabled when I loaded the
bcm43xx module... are you sure its enabled?

That being said, I have to agree Ubuntu's wireless for the bcm43xx
series is abit flaky ... my connection is somewhat unstable - sometimes
it works great, other times it seems to stall.  I think this can be
traced to the softmac authentication...  But sorry, I don't have any
simple answer for you.  When you replaced the firmware, did you reload
the module (ie rmmod bcm43xx and then modprobe bcm43xx)?  I find that I
usually have to do a `sudo ifdown eth1 down` and then a `sudo ifdown
eth1 up` after the module loads for it to correctly load my settings...

Sorry, hope this helped somewhat, but I'm still kind of confused as
well...
