Hi
On a laptop (1525 dell) I've got this wireless adaptator :
Code:
03:00.0 Network controller: Broadcom Corporation BCM4312 802.11a/b/g (rev 01)


I think I must use the kmod-wl non free driver of the rpmfusion repository : http://download1.rpmfusion.org/nonfree/fedora/releases/12/Everything/x86_64/os/repoview/index.html


    # 10-Nov-2009: kmod-wl-2.6.31.5-127.fc12.x86_64-5.10.91.9.3-3.fc12.6.x86_64
    # 10-Nov-2009: kmod-wl-5.10.91.9.3-3.fc12.6.x86_64

First : why 2 versions ?
Second : Can I use it with the free default kernel :-) or should I install the non free kernel :-(

Thx for all !

wait for this afternoon. Think I have the same and it works with linux-libre and openfwwf. But I'm at work for now.
You can try that:

Thx!

Yes! I wrote them some time ago to say that my wifi card which is not listed works too.
Openfwwf is installed by default on fedora 12, so it is on blag 119k. But linux-libre doesn't load b43. So you have to copy the firmware in b43-open.
After:
Code:
#rmmod b43
#modprobe b43

Then it would work without rebooting.
I'll see that later because I'm not on the right box now.
It works too with broadcom sta driver, you have to compile with a linux-libre. But it's non-free.

I try to install a b43 driver for a wireless card
My card : BCM4312 802.11b/g [14e4:4315]).
uname -a 2.6.32.11-libre.99.fc12.x86_64
This link http://wireless.kernel.org/en/users/Drivers/b43#Supported_chip_types seems to say that a kernel 2.6.33 is necessary. But I don't have this...

I've installed the firmware in respect of the link
http://wireless.kernel.org/en/users/Drivers/b43#device_firmware_installation
the install have created a dir b43 that I rename to b43-open

So, return errors of dmesg | tail
(23:11:52) cyrille: ssb0:0: Missing Free firmware

After the IRC discussion, I tested a live CD of F13. After boot, use the b43 driver. But don't work : only the ucode5 is present and the system asked the ucode15.... Same situation, with the rename of the dir (b43-open).
I tested too to compile myself the driver like explain
http://wireless.kernel.org/en/users/Drivers/b43#device_firmware_installation
with the source file : broadcom-wl-4.150.10.5.tar.bz2 and too this source file
broadcom-wl-4.178.10.4.tar.bz2 but always the same error notification.

Finally I think that although this card is glabally supported, this version is not 14e4:4315 with the actual kernel in any case.

Finally, I have installed broadcom-wl from rpmfusion nonfree. It works great but it's non free :-(

So, solved, but not really satisfactory[/b]

broadcom-wl is the broadcom sta driver. It works with a linux-libre but you have to compile it yourself. I use it before openfwwf works on blag. Because openfwwf needs a 2.6.30 or + linux kernel. And 90k has a 2.6.27 one.
You may try if openffwf works with your box by trying a Trisquel live CD.
