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

Hey everyone,
  After much tears and many blurry eyed hours staring at forum posts, I got the native bcm43xx driver to work.  Essentially, ndiswrapper and bcm43xx conflict, so if you upgraded from Breezy (like I did), then Dapper now tries to load bcm43xx, which is why ndiswrapper does not work.  You have two options, outlined here:

https://wiki.ubuntu.com/WifiDocs/Driver/bcm43xx

Just look at the section for Dapper.  I got my BCM4306 (dell branded)
card to work by removing all traces of ndiswrapper and then using the
firmware package provided in the link.  That was the real crux-I was
trying to use the same version as the one on my windows partition, but
it kept failing.  Installing the deb, and then manually copying the
firmware files from /usr/lib/firmware/bcm43xx to /lib/firmware and
following the rest of the guide did the trick for me.  (For some reason,
the dpkg-reconfigure for that package wasn't working for me, so I
manually copied it over).

Btw, eth1 is now the wireless device (when using bcm43xx at least).
