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)
