HOWTO: Use b43 driver with 14e4:4315 (Broadcom bcm4312 rev 01)

[murasan]

Special thanks for yours answers...I try to tell(in my bad english) how is my situation now for if it can help to others...STA work very,very well but not is free and it don't like me, perhaps i don't use my broadcom in mode monitor never but i like can make it if i want..
I install b43 from synaptic and put new kernel from here(it work well and like me) after follow the spanish "how to" for install the driver..all ok and i can put my broadcom in mode managed,monitor and ad-hoc with
sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode monitor,managed or ad-hoc
sudo ifconfig wlan0 up
Only some times after reboot don't find signals..for this i removed Networkmanager and put
wicd and rutilt,this two works better than networkmanager but not well of all.

The great problem came, i think, for use airmon for know if broadcom realy was in mode monitor...with sudo airmon-ng wlan0 it make other mon0 and think it no is good for me after reebot...with:
sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode monitor,managed or ad-hoc
sudo ifconfig wlan0 up
I work ok and not need mon0....I remove aimon and try with Kismet, it work fine...

This sound well:
"The key to getting your card to work is have the latest kernel for Ubuntu Lucid Lynx (2.6.32-16.25) is the latest i believe. Installing the bcmwl package and letting it auto load. Cutting the firmware with the git repo fwcutter and specified driver. Installing the specified compat-wireless package. And finally unloading the wl driver and loading the b43 driver manually after boot. If all the steps are followed correctly you will have a working wireless card capable of connecting from much farther distances than possible any other way along with other features that may also be helpful "

Read this for over with my bad english sound well..i wil translate it and will try but i am very very nood...thanks thanks

Sweeeet! Worked perfectly for me - Dell Latitude e6400 with card:

(output from lspci):

0c:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)

running Ubuntu 9.10 Karmic Koala, kernel:

(output from uname -a)

Linux africa.cv.com 2.6.31-20-generic #57-Ubuntu SMP Mon Feb 8 09:02:26 UTC 2010 x86_64 GNU/Linux

nice - thank you Bigadada_saba - thanks!!!

fyi - i used this from much earlier in this thread from poster Bigadada_saba:

1) i did a fresh install from the live cd
2) after the installation in made sure and turn on the wireless even-though is not detected.
3) then load the the live cd as a source in synaptic
4) then search for broadcom
5) install the drivers
6) got to system/administration/hardware drivers
7) install the STA driver
restart your computer then it should be working perfectly

...and it did work perfectly....on my system as spec'd above

Just to clarify; Are you using the wl driver from the STA package or the open source b43 driver?

chenxiaolong, yea I know what you mean, but - yea - it's a looooong thread, ... check out post #204 in this thread, i.e.

December 6th, 2009 #204

it's back on page 21 of this thread...user with handle of "Bigadada_saba" posted the solution I referenced.

rlelliott - loaded up my ubuntu 9.10 install disk, then chose the following 2 packages in synaptic from the install cd as source:

Description column: Broadcom 802.11 Linux STA wireless driver source
package name: bcmwl-kernel-source

and also this package:

Description: Modaliases for the Broadcom 802.11 Linux STA driver
package name: bcmwl-modaliases

(note 2nd package was a dependency of the STA driver)

hit "apply" in synaptic, then rebooted..and voila, wireless was working perfectly - it's been up for hours now no hiccups, and working fully with WPA2-AES - when i connected it prompted with a dialog box for the passphrase, then connected perfectly. thank god I didn't have to go through working with wpa config file again...

Ahh...I see. That was a while back .

After testing distro to distro, I can finally conclude that b43 WILL WORK PERFECTLY in DMA mode with any Linux system running kernel 2.6.33. Is that great or what?

That is great, but is that with compat-wireless? Because I'm running Slackware-Current with 2.6.33 (vanilla kernel) and still get DMA errors with the b43 driver.

b43 only works if I load and unload wl first like in that lucid howto.

[chenxiaolong]

Sorry, I wasn't very clear in my previous post. I got it working without compat-wireless and for some distros, it would work without loading and unloading wl, while in others, I had to.
