New brcm80211 driver guide for Broadcom wireless cards

[goldeneyexs]

Attached you will find a patch that I can only promise will cleanly apply to 7d5fc5c4d03.

Save the file to your home then run the following commands:

#from ~/linux-next if you followed OP
git apply --check ~/brcm80211.txt
#IF NO ERROR CONTINUE
git apply ~/brcm80211.txt
cd drivers/staging/brcm80211
make

If the patch does not apply cleanly try (these steps are for the future after this post and the patch becomes stale), then try above again.

git reset --hard
git checkout 7d5fc5c4d03

goldeneyesx:
You makefile is just a blank text :S
Is the driver working in your system without any crash?
I could use it under Debian Squeeze (the driver is included by default...), just installing the firmware from Squeeze non-free repository. But it caused many crashes on my system. That patch should work, I think, but I don't know how to aply it (may I edit the source code, maybe?).
Anyway, I downloaded the Broadcom STA driver (wl) directly from Broadcom website. It is a little more up-to-date (sorry for my English ) than the one I was using in Lucid, but seems to be much more stable...

Sorry about the blank makefile...copy/paste error I guess. I have yet to have a crash running the new patch. I will not say it's fixed all issues until I use it for a few days, as the problem could take up to 6 hours before it would crash.

I had an issue with the STA driver and wpa2 enterprise disconnects, which may or may not have been caused by network manager, which I have since removed trying to troubleshoot the crashes.

If you follow my new directions above, you will get the patch I mentioned.

my bcm4313 doesn't capture any packet with airodump, I read somethind about wireshark and b43 drivers but I haven't understand very well...

[naveedahmadkhan]

Having the exact same problem as alan2796.

Running bcm4313 on an eeepc 1015pem

I have a feeling I'm missing some includes but am not too sure. Anyone has ideas?

I am also having same problem, Plz help us

[some-one]

I've seen that as well, I really don't know how to solve the problem

The driver now is divided in two, brcm full mac and brcm soft mac. The first one doesn't compile, but the second one does.

For compile you have to download the driver from this link:
http://git.kernel.org/?p=linux/kerne...4d1e202;sf=tgz

You always can download the latest version browsing the git:
http://git.kernel.org/?p=linux/kerne...bc0156;hb=HEAD

Uncompress the file and then go to this folder:

cd linux-next-52bac5b/brcmsmac/

There is a Makefile in that folder, you have to add this lines:

KDIR    := /lib/modules/$(shell uname -r)/build
ccflags-y += -I$(SUBDIRS) -I$(SUBDIRS)/../include -I$(SUBDIRS)/../util -I$(SUBDIRS)/phy

default:
	echo $(PWD)
	$(MAKE) -C $(KDIR) SUBDIRS=$(shell pwd) CONFIG_BRCM80211_PCI=y V=1 modules

And then you have to erase some function calls to "no_printk", I don't know what are they for, but there are just for debugging (for the driver developers), you have to execute this command

sed -e 's/no_printk(.*)//' -i wl_dbg.h

Without that command the driver doesn't compile.

Then execute make and if there is no problem the driver compiles. One more thing, now the output file is named brcmsmac.ko

you can renamed it

mv brcmsmac.ko brcm80211.ko

And then do the things from the guide.

brcm80211 is not getting data packets... I have bcm4313

Was it able to do this before? From my knowledge it wasn't able to before but I may be wrong.

itwas not able... I read something about wireshark but I don't understand...

Installing wireless via Additional Drivers worked yesterday, but today I reinstalled Ubuntu and Jockey Backend kept crashing.

I followed your guide under Ubuntu 10.10 x64 for my BCM43224. Thank you for the easy step by step guide, it worked perfectly. With the generic driver from Additional Drivers my ping was always fluctuating, speedtest.net alone showed it jumping up and down every second. With the driver from your guide it is now stable and oddly enough I'm hitting speeds slightly faster than in Windows 7.

Thanks again.

This driver shows up in the driver list as "Broadcom 802.11n", but it will only work with my router in bgn mode. If I set my router to "n only mode", the connection would drop, and it would repeatedly ask for my password. Is this something that can be easily fixed?
