Hey everyone,

I have spent quite a few weeks trying to resolve the problems I have been having with setting up my wireless card on my netbook to work flawlessly with Gentoo. After working on this awhile, I have gotten my card ALMOST working, but now I have encountered a bug that I cannot find any solution to.

The card can get online fine, I can access the internet and download small files with no problems. When I download a large file, (i.e. emerging something like Firefox) after about 6 seconds of connectivity, dmesg | tail prints out "No probe response from AP <address> after 500ms, disconnecting." And the download fails. I have wpa_supplicant setup to try to reconnect, but it just loops saying it cannot connect due to a timeout. If I reload the B43 driver, it appears to work fine again (until I download a large file.) That is, ifconfig wlan0 down && ifconfig wlan0 up fixes the problem so I can browse the internet no problem, but if I download something I get the "No probe response..." error.

I have a HP Mini 1009TU Netbook on which I have installed the latest version of Gentoo. The laptop uses a Broadcom B4312 card.

Just for reference:
lspci | grep Broadcom reports:
01:00.0 Network Controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

uname -a reports:
Linux caspar 2.6.32-gentoo-r7 #5 SMP Mon May 17 10:32:20 EDT 2010 i686 Intel(R) Atom(TM) CPU N270 @ 1.60GHz GenuineIntel GNU/Linux

lsmod reports:
b43
mac80211

I have been having quite an interesting time getting my wireless working. These are the steps I had to follow to get it to the point I am at:

1) Followed Gentoo Guide to setup the b43 driver / card firmware.
- Allowed me to iwscan list fine, but I could not connect to the internet due to DMA errors. My laptop also lagged intermittently due to a constant DMA controller reset from the B43 driver timing out on DMA transfers.

2) Patched the b43 driver to Force PIO Mode. This allowed me to connect to the internet/browse the internet no problem.
- Encountered an issue where I cannot download large files. When downloading files for an extended period of time, dmesg | tail reports "No probe from access point <address> after 500ms, disconnecting" and I cannot reconnect until I reload the b43 driver.

I cant think of there being a problem anywhere but the B43 driver/firmware.

I would appreciate any help you can provide.

Thank you.

*EDIT* I am trying to increase the beacon poll timeout monitoring interval by editing my kernel source again.. ./net/mac80211/mlme.c
*EDIT* Nope, that didn't fix it. Now it just waits a long period of time not downloading before reporting the timeout :cry:

Have you tried the broadcom-sta driver?

Thanks for the reply man.

I think I did at one point; but that may have been before I found the DMA problem. I switched to the Broadcom driver which I downloaded from the Broadcom linux page at one point.

I will try that again.

Thanks again!

No need to download, it's in portage, just emerge it
Code:
emerge broadcom-sta

Just need to add to package.keywords if your running stable , its an ~arch package

heh I am actually having some issues with my kernel configuration with that at the moment. Apparently the sta driver requires CONFIG_LIB80211 and not CONFIG_MAC80211... It also says I shouldn't have CONFIG_B43 asserted either. I am working on getting that fixed at the moment :<

Before you can emerge the broadcom-sta driver, you need to add this to your make.conf (for anyone reading this with a masked ebuild error when trying to emerge)

Code:

ACCEPT_LICENSES="Broadcom"



*EDIT* What exactly is the STA driver? And how is it different from the B43 module / firmware? This is probably a dumb question, but I am having problems finding a clear answer.
Never mind, apparently it is a proprietary driver from Broadcom that has a lot better performance :) I wish the Gentoo wiki page had mentioned that.

Thank you, that fixed it. The STA driver is a LOT better than the B43 module. I can download at rates exceeding 10 kbps now, and I stay connected!

Thanks again.

Glad to hear it worked :) . I had tried the b43 before but had all kinds of issues too, that's why i also went with broadcom-sta.

Quote:
ACCEPT_LICENSES="Broadcom"

I forgot about this.
I got annoyed with accepting licenses and am guilty of using ACCEPT_LICENSES="*".

Indeed, broadcom-sta are pretty good nowadays.

after spending some time trying to resolv the problem with my b43 card (Broadcom Corporation BCM4312 802.11b/g (rev 01)) I found the solution and now the card is working pretty stable.
The problem was that each time 6 seconds after each AP association the connection was dropped with this error in the dmesg:

No probe response from AP xxxxxxxxxxxxx after 500ms, disconnecting

The fix is to disable the QOS of the driver.

Quote:

sudo touch /etc/modprobe.d/b43.conf
echo "options b43 pio=1 qos=0" | sudo tee -a /etc/modprobe.d/b43.conf


thanks to chenxiaolong

P.S. The QOS setting depends of the processor, for some it have to be 1

QOS on --> Intel Core Duo, Intel Atom
QOS off --> Intel Core Solo, Intel Core 2 Duo, Intel Core i3/i5/i7, and AMD

Personally I got round the problem by turning off the "Enable Powersave by Default" on all 3 of my laptops, and the desktop with the USB dongle.

But glad to see the broadcom-sta drivers work as well.

which driver are you using? br4? what is the card model?
because when I try
iwconfig wlan0 power off
I got
Error for wireless request "Set Power Management" (8B2C) :
SET failed on device wlan0 ; Operation not supported.

Using the b43 in kernel driver...

Works wonderfully. Was having problems with random disconnections, but once the powersaving option was turned off it worked well.

The card here is 4312, b43 is build as a module and my the firmware is version 478.104 (2008-07-01 00:50:23), probably power save isn't working yet in Broadcom 4312, but I'll test with your firmware version also (just in case) :)

what version of net-wireless/b43-firmware are you using?

not what I've asked for...
what is the output of emerge -s b43-firmware?


hmm, acctually I used not the gentoo provided firmware, but broadcom-wl-4.178.10.4.tar.bz2

Ok, I emerged b43-firmware and now I have:

Code:
[86416.564235] b43-phy1: Loading firmware version 410.2160 (2007-05-26 15:32:10)
[86416.566662] b43-phy1 debug: b2062: Using crystal tab entry 19200 kHz.

[86417.952396] b43-phy1 debug: PIO initialized
[86417.952416] b43-phy1 debug: QoS disabled
[86417.961137] b43-phy1 debug: Wireless interface started
[86417.965771] b43-phy1 debug: Adding Interface type 2


but setting the power save mode is still not working
Code:
iwconfig wlan0 power off                       
Error for wireless request "Set Power Management" (8B2C) :

you are using kernel 2.6.34, you should use that package.
I have the same card on my dell laptop, using b43 and that package and it works great
unless your trying to get an special feature on, in that case, I apologized, I though you have problems getting the adapter to work.

hmm, yes with this firmware I think is better - the wifi connection is much stable
what about the qos=0 and power save settings? Do you use them?
what about the drivers's DMA and PIO?
I'm using it with PIO mode on and DMA off and the CPU is under heavy load for 7-8 M network traffic the first CPU is 85% ...

I don't use qos or powersave
have no idea what DMA and PIO cause and my cpu isn't heavy loading at all.

Sorry, I meant here in the kernel...

Under Networking Support -> Wireless.
