After install the module, close terminal and reboot the system

Wifi work

Tested in linux mint 12 kde and linux mint debian

That's indeed the easiest way to get it working on Mint. Also works on 11.

Note that this can't be used for other Broadcom models. Only the BCM4312, a small sized, low-power wifi chip usually found in older netbooks (it has no 802.11n yet), uses firmware-b43-lpphy.

I'd like to add a minor detail someone can hopefully benefit from.

My wired network interface was broken, so I was unable to successfully apt-get install the installer (which downloads the firmware to be exploded). Using another machine, I could download and transfer the mentioned .debs and .tgz to the target machine, but the installer had no switches to tell it you already had the local file and insisted in connecting.

I managed to open the DEB using Debian Package File Viewer and found out the installer just invokes b43-fwcutter to extract the firmware from broadcom-wl-4.178.10.4/linux/wl_apsta.o and lays the whole bunch of files it extracts in /lib/firmware/b43. It previously deletes any previous versions, and then cleans up its own mess, but essentially that's it.

So I manually opened the tgz, ran b43-fwcutter on wl_apsta.o and moved all the extracted firmware files to /lib/firmware/b43, rebooted, and then the infamous Broadcom 4312 was up and running.

Hello guys,
I'm so excited for this new operating system (Linux Mint), I come from Windows OS, but now I'm really satisfied.
Please have patience with me, because I'm still learning the basics of Linux.
I have a small problem. The wireless does not work.
I followed this little guide (which also corresponds to the one mentioned, but to no avail) :
http://community.linuxmint.com/tutorial/view/796

Because it corresponds exactly to my wireless card:
04:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
My computer is an Hp pavilion dv4-1190el and I installed Linux Mint 14 Xfce 32bit all codecs
Which I command string or write to the terminal to show you my situation(unfortunately, not working)?
Thanks in advance, best regards.
Antony

@ nick85x: Please open a new topic for this. Have you already tried installing firmware-b43-lpphy-installer?

Thank you. even if. I wrote a message here. because the wireless card is that. but the firmware installation mentioned above, not by results. that is to say the wireless does not work. I have also written a new topic, here: http://forums.linuxmint.com/viewtopic.php?f=53&t=129309
I'm hoping for some good soul that can help me.
Good bye

Thanks a lot guys,
Now the wireless is fine.
