New brcm80211 driver guide for Broadcom wireless cards

[krvermeulen]

Thanks for the guide, all's working fine. My laptop hung a few times after installing the driver, making me switch it off and on with the power button. It seems to be doing fine now.

If I read one of the posts correctly, the installed drivers are all being deleted by doing a kernel update. Is that correct?

Thanks again for helping this Ubuntu n00b =).

EDIT: Double post.

Hi dreamaker.jorge, your problem is that you need to uninstall the packets b43, b43legacy, firmware-b43-lpphy-installer,

Configurando firmware-b43-lpphy-installer (4.174.64.19-4) ...
Not supported card here (PCI id 14e4:4727)!
Use proper b43 or b43legacy firmware.

It says that your card is not supported, I think you have the card BRCM 4313 (for the PCI id).
Go to Synaptic and uninstall that packets and then try with the guide of the first page of this thread.

There are new commits but they still not compile. The problem is in this commit
staging: brcm80211: Fix WL_<type> logging macros
In it the developers added the functions printk and no_printk, but they forgot to implement them.
I made a little scrip to correct the code, it only erases that functions from the code.

When you go to the directory ~/linux-next/drivers/staging/brcm80211
You need to do this:

create the scrip

nano script.sh

Add:

#!/bin/bash

for file in ./brcmfmac/*
do
	sed -e 's/no_printk(.*)//' -i ${file}
	sed -e 's/printk(.*)//' -i ${file}
done

for file in ./sys/*
do
	sed -e 's/no_printk(.*)//' -i ${file}
	sed -e 's/printk(.*)//' -i ${file}
done

Save and exit

execute

sudo chmod 777 script.sh

execute

./script.sh

and then compile the driver

Hope this help someone. And again sorry for my poor English

Hey, thanks for the how-to! I've sucessfully compiled (using the updated linux-next) on ubuntu 10.10 Dell Vostro 3500.
Now the latency is regular and on 1.3ms inside the lan as expected. Before the fix it often got to 200ms.
Now I just wish ubuntu devs used this driver instead.
Thanks a lot!

I did everything per the guide, but when I tried
"sudo insmod /lib/modules/`uname -r`/brcm80211.ko"
I got an error saying there was an invalid parameter. I continued on with the rest of the steps. Now, when I try to login, the screen goes black and keeps repeating the last two seconds of the login music. Any ideas?

I have Ubuntu 10.10 on a Dell Studio XPS 1640 w/ a Broadcomm 43224 wifi card.

In reference to the previous post, I was having problems with my wifi before I tried this guide. I could not get the wl module to load. I don't know if that means anything.

I had that error, but I found that the notebook has a button to turn off the wl (and bluetoth) than to boot the system automatically shuts down, turned it on and ready
