Thanks for your report! Do you need that all options at all? I think
hwtkip=0 is default one. Parameter qos should not matter. AFAIK pio is
needed for some BCM4321s only. I didn't check what bad_frames_preempt
does.

Hm, that's interesting. wl should work too.

As for speed, it's known issue. I still hope to get patches ready for
2.6.39 merge window.

What does happen when it doesn't work? Do you get scan results? Can
you associate? Get IP? Transmit?

One request: please blacklist b43, do cold boot (turn off machine for
few seconds), then boot and load b43 with:
pio=1

I ask you for that, because it's possible that using DMA locks up your
card. In such a case further tests can give you false results.
Do you have scan results when using pio=1 after cold boot? Can you associate?

[Clemens Helfmeier]

Hello Developers,

I have just tried the current wireless-testing git tree with my bcm4322 device:

# lshw
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4322 802.11a/b/g/n
    Wireless LAN Controller [14e4:432b] (rev 01)

# dmesg shows:
[   11.358762] b43-phy0: Broadcom 4322 WLAN found (core revision 16)
[   11.400231] b43-phy0 debug: Found PHY: Analog 8, Type 4, Revision 4 
[   11.400257] b43-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2056, Revision 3

I had to apply this patch to b43-fwcutter in order to extract the firmware: 
http://lists.infradead.org/pipermail/b43-dev/2010-July/000225.html

Using WPA2, the connection is very stable, no connection break downs so far.

My dmesg log shows quite a lot of error messages (approx every 7 seconds in 
idle and more often when traffic is high):
[ 4015.044435] b43-phy0 ERROR: PHY transmission error
[ 4021.910720] b43-phy0 ERROR: PHY transmission error
[ 4028.866892] b43-phy0 ERROR: PHY transmission error

Thanks for your efforts to get my hardware working!

Best regards,
 Clemens

Yeah, there was some discussion about getting newer firmware. It's
unfortunately available only in huge firmware and Broadcom doesn't
give a sh* about providing open source community freely available
firmware. That's all about their openess and positive talks brcm80211
related.

For now you have to download huge firmware (and hacking extractor) or
try linking ucode16_mimo to ucode16.

We have some positive reports and not-so-much (coming for example from
Larry). Good to head there is one more person having this working.

Just for sure: can you try forcing rate to 1M, 2M or 11M? Does it
noticeably lowers amount of reported PHY errors? The command you need
to use is like:
iwconfig wlan0 rate 1M
iwconfig wlan0 rate 2M
iwconfig wlan0 rate 11M

The attached patch should fix the PHY transmission errors, which happens 
whenever the rate control code tries to set an OFDM rate. With the patch, those 
rates will not work, but no errors will be printed.

You can also lock the rate at 11M (iwconfig wlan0 rate 11M) to get rid of those 
errors.

Hi Rafa?,

I also have a bcm4322 chip, which works with WPA2 using 2.6.38-rc5.

This is the only thing I had to do to make it work.

I'm seeing about the same here.

Furthermore, I get about 5% packet loss when pinging my wireless
router (with no other traffic).

iwconfig says that my rate is 11 Mb/s, but since I expected it to be
54, I figured this might be wrong, so I tried
% iwconfig wlan0 rate 11M

This appears to solve the problem completely! I have not seen any more
errors and my packet loss is 0%. (The download speed is still
suboptimal, but I read that you already have some patches for that, so
I'll just wait for when they are posted.)

Thanks for making this work! (It is infinitely better than the wl
driver...). If ever you need some testing of new patches related to my
card, let me know.

Cheers,

Tom

Locking the rate at 11M makes the driver not output any more error messages 
here ,too.
Thanks for your work!

Thanks for your tests, however I can not offer you anything right now.
I hope it will get more stable when we get TX patch, some general PHY
rev 3+ improvements and DMA fix. Will try to remember to ping you then
:)
