Good going.

lwfinger, I just noticed this thread. Well done and many thanks for this contribution.

Going steady for 12hours now.No problems whatsoever with b43
Receive rates in excess of 20Mbps

Broadcom Corporation BCM4312 802.11b/g (rev 01), 14e4:4315
Driver works flawlessly, no errors in dmesg, survives suspend-resume cycles.
Thanks again.

Its not as stable as I wish because the driver often hangs on system startup.

Someone/something has broken the source at compat wireless driver archive and so I am not able to test any newer version since 06.09.2009.

What has been broken you can see here:
Ubuntu Forums - View Single Post - [ubuntu] Does ubuntu supports Intel WiFi Link 5300 (AGN) network card?

I'll pass the problem with the build on to the compat-wireless folks.
I know how it happened, but I'm not sure what it takes.

There have been no changes in the LP PHY code (4315) since the
beginning of September as the main developer has been having trouble
with his machine.

If you have any definitive diagnostics on the hang at bootup, please
let me know. Does the entire boot process fail, or how would you
describe it?

The only thing I can tell you about the 'hanging' is, that if I start the system in recovery mode the the text stops after calling for b43 driver and a few seconds later it switches to black screen and stays there.
The only thing that helps after that is a hard reboot (power switch) and to try again - after some trys it suddenly works.

Without some diagnostics, this will be hard to fix. The symptom has
not been reported by anyone else.

I'm using kernel 2.6.30.5-43. Apparently the broadcom-wl-4.80.53.0 firmware doesn't work. Dmesg says

b43 ssb0:0: firmware: requesting b43/ucode15.fw
b43 ssb0:0: firmware: requesting b43-open/ucode15.fw
b43-phy0 ERROR: Firmware file "b43/ucode15.fw" not found
b43-phy0 ERROR: Firmware file "b43-open/ucode15.fw" not found
b43-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version. Please carefully read all instructions on this website.

Any ideas on what firmware I should use?

[chenxiaolong]

Nevermind. The correct firmware was listed on the Linux Wireless B43 page, but not under the Fedora section.

You need the firmware from at least 4.150.10.5.

If you have Internet while running Linux, just do

sudo /usr/sbin/install_bcm43xx_firmware

If you don't have Internet access, you will need to download

http://mirror2.openwrt.org/sources/b...0.10.5.tar.bz2

The driver file with the firmware is
broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.o
