A small error in b43

A small error in b43

[Gregory Bellier]

Dear list,

I would like to test the b43 driver for a BCM4322. I tried with 2.6.38.2 
and 2.6.39-rc2 but I'm stuck with a firmware error in dmesg :
[   75.922582] b43-phy0 ERROR: Firmware file "b43/ucode16_mimo.fw" not found
[   75.922587] b43-phy0 ERROR: Firmware file "b43-open/ucode16_mimo.fw" 
not found

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.

I have b43-fwcutter v13.

# b43-fwcutter -w /lib/firmware/ broadcom-wl-4.178.10.4/linux/wl_apsta.o

Did I miss something ? I promise I read carefully.

Sorry, I wrote this email in several times. I finally did a symlink in 
/lib/firmware/b43 : # sudo ln -s ucode16.fw ucode16_mimo.fw
And it worked like this.

Symlink should work for now. The real solution is not use:
http://mirror2.openwrt.org/sources/broadcom-wl-5.10.56.27.3_mipsel.tar.bz2
and the newest fwcutter (which is needed to support this 5.10.56.27.3).

I still hope to get easy access to newer broadcom-wl, so I'm waiting
with updating howto on wiki page. I just mailed OpenWRT team day or
two ago.

I'm not sure if those two firmware files are equivalent or not.

There is a new version of b43-fwcutter in the git repository at 
git://git.bu3sch.de/b43-tools.git that knows how to extract the firmware from 
URL http://mirror2.openwrt.org/sources/broadcom-wl-5.10.56.27.3_mipsel.tar.bz2. 
After untarring, the object file is
broadcom-wl-5.10.56.27.3/driver/wl_apsta/wl_prebuilt.o

Yes, it works properly with this one !

Thanks for your report! :) Support in 2.6.38 is known to be speed
limited. Actually, if you check
http://wireless.kernel.org/en/users/Drivers/b43 , we report BCM4322 as
supported in 2.6.39+. With this newer kernel you should get 54M TX.

How did you test this speed? Was this iperf or something else? 1.2MBps
is 9.6 Mbps. I was able to achieve 15.2 Mbps (1.9 MBps) with the same
card.

What were the conditions? Were you far away from AP?

You can see my comparison for PHY rev4, which means for example
14e4:432b: http://zajec.net/blog/view/2011-b43-n-phy-rev3plus-performance

Thanks, I'll try nc && dd.

Did you connect your server by cable to the AP?
