Title:
  Broadcom BCM3415 wireless: driver does not work (Natty/Oneiric)

Status in “bcmwl” package in Ubuntu:
  Expired

Bug description:
  Installed both Ubuntu Natty and Oneiric (actually, Mint 11 and 12, but
  this does not seem to be caused by the Mint desktop) on a Lenovo
  Ideapad S10e. Installer and desktop offered to install broadcom STA
  drivers (the device is a BCM3415 802.11g wireless). Wireless did not
  work in either case. In the latter (Mint12/Oneiric), I think it
  installed bcmwl-kernel-source_5.100.82.38+bdcom-0ubuntu4_i386 . Note
  that I had no problems with wireless in Ubuntu 9.x (I deleted it and
  don't remember whether it was 9.04 or 9.10).

  I tried "apt-get install b43-fwcutter", but this didn't work either.

  Finally, I downloaded the source from
  http://www.broadcom.com/support/802.11/linux_sta.php (32-bit, hybrid-
  portsrc_x86_32-v5_100_82_112.tar.gz) and compiled it. (It needed to
  repair a bad path in the Makefile using a symlink in the source
  directory). After installing the module 'wl', wireless networking
  worked through network-manager.

  I have difficulty in finding the best way to get wifi working after a
  reboot, but the following sequence seems to lead to working wi-fi
  (b43-fwcutter is installed, hardware driver is disabled in settings
  menu):

  - - - - -
  modprobe wl
  # result:  kernel message "module license 'unspecified' taints kernel", and no wi-fi again.
  modprobe b43
  # result: kernel message "ERROR: Firmware file "b43/ucode15.fw" not found" (and other similar messages).
  rmmod ssb b43
  modprobe wl
  - - - -

  The strange thing is that the 'wl' module only works after I have
  loaded and unloaded the b43 module. I guess that I will put this
  sequence in my rc.local, but it would be nice if it was streamlined.
  Below are the relevant parts of my system log:

  ### modprobe wl  (first time)
  Here is the relevant kernel log:
