Re: BCM4313 & brcmsmac & 3.12: only semi-working?

[Sébastien Le Preste De Vauban]

I'am in kernel 5.8.3.

Today I updated from .2 to .3.
I had not used wireless from a long time (+1 year) in this notebook.
So when I successfully connected to the router,  and started browsing,
I had a complete freeze of my system. Not even ssh access.
Later  I had the same complete freeze when I closed the lid; when I
went back to the device it was completely frozen.
journalctl -b -1 --system does not throw anything significant, no
indication of a kernel panic.

Now I am back to wired connection and no problems so far. So I suspect
it's the wireless card.

l$ sudo lspci -vnn -d 14e4:

For now I have blacklisted this modules just in case.

Has anyone been experiencing this issue in the aforementioned kernel version?

I did get my hands on same device as Michael has/had and it now sits in 
my developement laptop. Just need to find some time to give it a spin.

any update on this issue?
One of my relatives would like to get rid of that Ralink wifi stick she
has been carrying around for 1.5 years now since the internal wifi in her
Thinkpad E130 suffers from this problem.

I did a test with all Bluetooth modules unloaded that I could find but 
throughput was still very low (about 4 Mbit/s with brcmsmac, my atheros USB 
stick archived about 110 Mbit/s).

I don't know. I think I have Bluetooth somehow enabled but I'm not really 
using it. I definitely don't have any Bluetooth devices connected. I could try 
to unload/disable Bluetooth it to see if it makes any difference.

Thanks. It shows you have have the same bt-coex version as Michael. I am 
not familiar with bluetooth side of things. Are you both using bluetooth 
on 4313?

I also noticed the following:

o Watchdog calls itself wl0 while interface name is wlan0.
  Might be a good idea to change it.

o what does "capabilities/regulatory prevented using AP HT/VHT configuration, downgraded"
  mean?

Probably in US, but we are in an office in the Netherlands and do not 
have every flavor of board available. I will dive into some boxes again 
with this info.

The patch is just to provide me with extra bt-coex related information 
in the kernel log. So if you can provide that to me I have to info 
needed to look in the proprietary code base to determine what is missing.

Ok, that was easy.  Now it loads, but wifi link still

Hmm. The function brcms_btc_ecicoex_enab() is calling itself. Please 
remove that call as it causes endless recursion and eventually reboot.

With this patch applied against 3.18-rc5, the machine instantly reboots
once brcmsmac module is loaded.  I'm still debugging this.

With this patch applied against 3.18-rc5, the machine instantly reboots
once brcmsmac module is loaded.  I'm still debugging this.

Hi Arend,

sorry for my late reply, it took me a bit to get the modules compiled with 
your patches. Here is the information from my card. During this test I had 
very bad performance with my wifi connection with big latency and lots of 
packet loss.

here, all the messages are not present in the compiled modules.

Well, it shows tx looks ok, but with download there is not much of that
going on. At least no large packets. However, I did find some missing
pieces related to bt-coex. Given that you device is a wifi-bt combo card
that is likely an issue for you. One of the missing pieces looks in
sprom for parameters and that is provided by bcma. However, it does not
seem to extract bt-coex related stuff. So I have attached a patch based
on 3.18-rc5 for bcma that dumps the sprom contents. Could you sent that
content to me.

Arend

Ok, I misunderstood you apparently, -- I only tried 2 patches,
while I should try all 4.  So here it goes.

I especially wrote that I have several days to try things out and
if you'll be quick it will be possible for me to test things.
You never replied before now (which is some more months later).

You didn't tell which kernel it is based on.  So I tried it on 3.16,
ofcourse the patches didn't apply so I hand-edited the debug
printf in drivers/net/wireless/brcm80211/brcmsmac/debug.c (in
3.16 it didn't use seq_printf yet).  So now I have a `hardware'
file (in brcmsmac/bcma0:0/ subdir in debugfs), but not
macstat.  Here's the contents `hardware' one:

chipnum 0x4313
chiprev 0x1
chippackage 0x8
corerev 0x18
boardid 0x1795
boardvendor 0x103c
boardrev P107
boardflags 0x402201
boardflags2 0x884
ucoderev 0x262032c
radiorev 0x1
phytype 0x8
phyrev 0x1
anarev 0xa
nvramrev 8


Since there's no macstats, I guess it is not very useful,
so before digging for too deep, I ask which kernel do you
want me to try here.

Thanks,

In our last email exchange I got the impression you switch to Intel 
board and did not want to keep replacing cards for testing. Nice to hear 
you have an alternative setup for this and I assume are willing to do 
some testing.

I submitted two patches upstream and additionally I have attached two 
other that are still under review. Could you try these patches and sent 
me the content of the two debugfs files 'macstat' and 'hardware' after a 
stall has occurred.

Arend

I had a bit of problem with the mmiotrace files. Well, my (virtual) 
linux machine had as it ended up swapping on my disk and went down the 
drain.

I still wanted to look at items 3) and 4) that Rafal mentioned although 
item 4) does not seems to apply to Michael's 4313 it may help yours. I 
submitted a patch to get counter statistics from the 802.11 core on the

I've no idea if there's any progress.  Meanwhile I've an easy way of
testing of my brcm4313 card in a mini-itx board with mini-PCIe slot.
It works rather nicely and the stalls are easy to trigger.
Running 3.16 kernel right now, tried to d/load a file from the
AP, -- boom, it stalled after 77Kb.

Since the previous discussion apparently ended prematurely and no patches
to try emerged, I don't have anything to try on it...

Thanks,

Hi,

I just wanted to ask if there is any progress on this issue since I haven't 
heard anything for a month. Please let me know if you need any additional 
information.

Arend,

As you noticed earlier, this is a WiFi card with BT. I've checked
siutils.c from SDK 7.14.43.7 (got it from Netgear R8000) and it has
three BCM4313 workarounds:


1) si_doattach
SI_MSG(("Applying 4313 WARs\n"));
si_pmu_chipcontrol(sih, 0, CCTRL_4313_12MA_LED_DRIVE,
CCTRL_4313_12MA_LED_DRIVE);

It's already implemented in bcma, see driver_chipcommon_pmu.c


2) si_epa_4313war
/* EPA Fix */
W_REG(sii->osh, &cc->gpiocontrol,
R_REG(sii->osh, &cc->gpiocontrol) | GPIO_CTRL_EPA_EN_MASK);

This is what you already implement in ai_epa_4313war


3) si_pmu_synth_pwrsw_4313_war
I don't think it's implemented.


4) si_btcombo_p250_4313_war
I also don't think it's implemented


The last one (si_btcombo_p250_4313_war) looks promising, the comment
above the function says:
/** WL/BT control for 4313 btcombo boards >= P250 */
I guess you need to re-implement this function and call it somewhere
in brcmsmac.

Thanks, Maximilian

I have been staring at differences brcmsmac and our internal driver 
(which wl is derived from as well). Would you be able to make an 
mmiotrace loading wl and brcmsmac.

Hi Arend,

Today I changed back to the BC4313 card to verify the speed is still slow. At 
first it was slow as I remembered it (down about 3 Mbits/s, up about 1 Mbit/s, 
measured with iperf).
I then booted an Ubuntu Live image to try the wl driver, just to verify that 
it performs better and the hardware is still fine. First on the Ubuntu Live 
image the speed with the brcmsmac driver were the same as in my test above. I 
the installed the wl driver, unloaded the brcmsmac module and loaded the wl 
module. That however did not work as something in the kernel crashed and 
wireless didn't work at all. I rebootet the system to test again in case this 
was a random failure. What was interesting after this reboot was that the 
wireless connection was fast with the brcmsmac driver. I got about 35 Mbit/s 
up and down speed. I then tried the wl driver again but it still crashed.

After this I rebooted into my normal Debian system and the brcmsmac driver was 
still fast. So what was different now than before. I realized that I always did 
a reboot, so the Laptop was never really off between the boots. I then shut 
down the laptop and waited a few seconds before turning it on again. And after 
that the driver was back to the slow speed.

I did not verify this a second time, but for now it very much looks like the 
wl driver is settings something in the card that is necessary for getting 
faster speeds. This seems to be preserved on reboot but not on poweroff.

I hope this my help you finding the problem in the brcmsmac driver. Feel free 
to ask if you need any addition debug information from me.

And for the record, my atheros usb card is still much faster, it reaches 
130 Mbit/s.

Greetings,
Maxi

Thanks for taking time to chime in. This chipset is a pain in the....
The label info does help. You have a 4313 with internal PA for which 
support was added later. The card that Michael has seems to have an 
external PA. The initial iPA support patch broke things for everyone 
with external PA so it was reverted. In the second round it was better, 
but it seems Michael still had issues. As he mentioned BT issues and his 
card shares the external PA between WLAN and BT I believe that there is 
a BT-coex issue.

What is causing your 4313 to seemingly do 11g rates is hard to tell 
without any debug info. I have that card over here, but in my cabled 
setup it is doing 72Mbps, ie. 11n rate. I can run a rate-vs-range test 
to see if there is an issue.

Thanks again and

Arend

Hi Arend,

I just saw this thread on linux-wireless and wanted to answer as it might be 
of interest to you.

I also own a BCM4313 wireless network card. About a year ago I reported some 
problems with reception strength which were then fixed after some time, 
debugging and testing passed. At that time I also did some throughput testing, 
but only had a 802.11g access-point to test. The results were not ideal, but 
also not too bad. So at that time I thought the issues were all more or less 
fixed and mostly fine. I also don't use wireless very much, so as long as things 
do work somehow acceptable I probably don't notice any problems immediately.
So it comes that only about some month ago I noticed that the throughput I 
measured with my 11g access-point (about half the rate than with an atheros 
card on the same ap) is about the same on a 11n access-point where it should 
be much faster. I didn't experience any stalls, but that may also be that I 
didn't use the card enough to really notice them.

I always wanted to report a bug because of the low throughout, but never got 
to it because of lack of time. I didn't want to provide a report saying just 
it doesn't work or it's slow without any data about it and a description how 
to reproduce it, as I think without this information a bug report is mostly 
useless.

I also had a look at the kernel changelog of the brcmsm driver and notices 
there was little to no activity lately. Because of this I also wasn't sure if 
there is still someone interesting in fixing bugs for this device.

As I was annoyed by the bad support for this card I decided it would be more 
easy and much less time consuming to simply buy another card than trying to 
get this fixed. So I bought a BCM43228 card, because it also supports 5 GHz. 
Only after it arrived I noticed that it was only supported by the 3.17+ kernel 
(not so much of a problem) and that it only seems to work in 802.11g mode 
(only slow speeds and no 5 GHz). At least I could use it in full 11g speeds, 
so it was a improvement.

So I still don't have a card that does simply work. As I hope the missing 
support for my BCM43228 will hopefully be added some time in the future it 
probably would still be worth fixing the BCM4313 card as other users will also 
benefit from it.

A friend of mine also has the same laptop than me and the same (or at least 
very similar) wireless card. He has told me he has also problem with stalls 
like Michael reported (if I remember the history of the thread correctly).

So I'm not really sure where I should go from here. I can try to provide some 
debugging information as time permits, but I don't know how much time I will 
have for this in the future. Of course ideally I want to use the BCM43228 card 
with full support, as it can work on 5 GHz.

Currently the BCM43228 card is plugged into my laptop, but I want to avoid 
swapping the cards more that very few times because the antenna connectors are 
only designed for very few (un)plug cycles.

If it's of any information, my card is labeled BCM-BCM94313HMGB on the 
sticker, the laptop where it was originally is a ThinkPad Edge E135.

Greetings,
Maxi

Could be. Maybe some BIOS issue. Can you make some hi-res pictures of 
the card and email them to me? If it is identical to what I already have

I also noticed that quite often it does not work after rebooing
the laptop from windows.  But not always. I thought maybe win
switches it into some mode which linux driver fails to notice,
but no, the fact that it sometimes works after windows tells
me that I'm not right.

And note please that the closed-source wl driver always worked
with both of these cards, at least when I was able to compile
it (the prob is always the same - no support for more recent
kernels; and I don't really like to use recent kernels (I myself
currently stay with 3.10.x stable line), but both laptops actually
requires recent kernels to work properly (either because of
great energy saving support in latest intel cpus, or because of
support of gpu in latest intel celerons) -- that's why I really
prefer in-kernel driver).

That to say - the fact that wl always works may tell that the
hw is fine and the prob is elsewhere.

Okay, so finally, today, without any updates from your side,
I opened up the laptop again and inserted a newly bought
Intel 6235ANHMW card instead of this creaky brcm4313.  This
card works right out of the box - plug it in and set up,
both wifi and bluetooth (I had numerous probs with bluetooth
too with brcm card), and it works on both 2.4GHz and 5GHz
bands.  Connection is very good and stable, I wasn't able
to trigger a single glitch no matter how hard I tried.

My only sorry is a lot of wasted time, efforts and money -
all that have much better value than trying to deal with
non-working drivers.  And my only wish is so vendors stop
using non-working parts in their hardware.. But oh well.

When it works it goes 50+ Mbps. I always tested at the same place and the signal there is good. D/load speed is 11Mb/sec steady. When it works. Today after powercycle it worked fine at 11 megabytes per second, I transferred several gigs of data.

I see. Today I ordered an intel wifi  card (which also works at 5MHz) and will swap bcm4313 with it. Since the notebook has to be disassembled for this (it doesn't have separate window for wifi card), and the procedure is rather complex I don't want to do it more times than necessary... ;)

I looked at the log. I see download commence because the packets

I looked at the log. I see download commence because the packets 
received of 1562 bytes length. So within one second I see little over 
200 packets so approx. 3Mbps which is not impressive but I don't know 
what can be expected. Indeed after that it stalls and we only seem to 
receive small packets of 179 bytes that seem to end up in 
cfg80211_mgmt_rx. It could be that the hardware is somehow bogged and 
can not receive at higher modulations as management frames are 
transmitted at lower rates. The hardware will drop packets that are 
having FCS (aka. checksum) errors. The brcmsmac is missing some code to 
read fcs error count from hardware, but I will get back to you with a 
patch that we can use to confirm this.

Yes.  Initially it started d/loading but some time later the d/load speed
reduced to 0.  It is possible to wait further, and after some more time
it will receive some more bytes/kilobytes/packets and stall again.  Overall
progress is nearing zero.

Did you check your kernel's config? You need to have

So, what should I enable?  I guess there's a suspection of tx path
problem (since according to tcpdump, the other side sends packets
our way, but our side does not receive them), so -e brcmsmac_tx
shold be okay to enable (and should be easy to filter out if
needed, too, I guess).  And using -e, now too, like this:

 trace-cmd record -e brcmsmac -e brcmsmac_tx -e brcmsmac_msg -e mac80211 -e mac80211 -e cfg80211

http://www.corpit.ru/mjt/tmp/brcmsmac-4313-trace-201409232.dat.gz is
the result from the following:

 modprobe brcmsmac (networkmanager is running)
 trace-cmd as above &
 wget http://ip-add-ress/random-file -O /dev/null

I waited for wget to stall (it d'loaded 240Kb) and hit
Ctrl+C.

The trace file isn't really that huge.

Thank you!

Ah, I read back the email from Sep 21 and it says:

I am surprised the capture contains something as -e is missing. Good to

Well, there are a few different trace events defined for brcmsmac. This
would enable the full set:

 $ trace-cmd record -e brcmsmac -e brcmsmac_tx -e brcmsmac_msg

It's been quite some time since I used them, but I think brcmsmac_tx is
quite noisy so you may only want to enable that if you already suspect a
tx problem. I always find it useful to enable the mac80211 and
mac80211_msg events too when debugging wireless, and I often enable
cfg80211 events as well (none of these are especially verbose).

Of course all of this depends on having the right config options
selected. Looks like the relevant options are CONFIG_BRCM_TRACING and
CONFIG_MAC80211_MESSAGE_TRACING.

Well, there are a few different trace events defined for brcmsmac. This
would enable the full set:

 $ trace-cmd record -e brcmsmac -e brcmsmac_tx -e brcmsmac_msg

It's been quite some time since I used them, but I think brcmsmac_tx is
quite noisy so you may only want to enable that if you already suspect a
tx problem. I always find it useful to enable the mac80211 and
mac80211_msg events too when debugging wireless, and I often enable
cfg80211 events as well (none of these are especially verbose).

Of course all of this depends on having the right config options
selected. Looks like the relevant options are CONFIG_BRCM_TRACING and
CONFIG_MAC80211_MESSAGE_TRACING.

Well. This log and the one from a few days ago only show me interrupt 
status changes, which does not tell me a lot. I do see that the hardware 
signals transmit completions, but it is far less informative then I 
hoped it would be. Maybe I am missing some debug configuration here?

It does not work at all anymore again.  Not only after resume but also
after could power up, it stalls right at start of wget for example.

And here -- http://www.corpit.ru/mjt/tmp/brcmsmac-4313-trace-20140923.dat.gz
is another trace, after insmod brcmutils & brcmsmac, starting trace-cmd record
(with network-manager running in the background), and running a wget on
http://ip-add-ress-of-the-access-point/somefile (which immediately stalls,

Hopefully this will help to find the problem.  And for the record, I'm

I can at least buy some other, better supported wifi adapter now, because
this laptop does not have a bios lock (is 6235ANHMW any good?)

No, I didn't have that opportunity.  As I mentioned before, the second
laptop where I faced the same problem with brcm4313 wasn't mine, and I
had to return it back to its owner, so I had nothing to test things on
for quite some time.

However, a few days ago, after I was searching for a good notebook of my
own (obviously without broadcom parts ;), another friend of mine sent me
a gift - a new laptop.  But this one has even worse wifi card (from linux
support PoV anyway) -- it is mediatek (formely ralink) MT7630e card.

After trying to build drivers for it for a while, I gave up, and an idea
come to me to swap this mediatek card with that broadcom 4313 card.
And surprizingly it worked - both laptops accepted the "new" cards and
I verified both works.  So now the mediatek from my laptop works in
my friend's hp envy, and his brcm4313 works on my new asus.

So from now on I again have some playground for this stuff.

As I mentioned before, the card appears to work fine, at least at
first, I wasn't able to trigger any lockups/stalls before.  Now
I can't trigger any stalls either, again, at least easily.

However, I found a 100%-reliable - so far - reproducer for the
initial behavour I described in the very first message in this
thread, which soon be one year old...

Namely, after resume, the card does not work. ARP works, ping and
DNS sometimes/somewhat work, inital TCP connection establisment
works, but eg http download does not work, it stalls almost
immediately.

Also during resume, I see the following kernel messages:

I dunno how related these are -- bluetooth is another function of
this card.


http://www.corpit.ru/mjt/tmp/brcmsmac-4313-trace-20140921.dat.gz -- this
is a trace collected after resuming from suspend-to-disk, after the above
kernel message, and doing this:

  stop network-manager
  rmmod brcmsmac brcmutil
  modpobe brcmsmac
  trace-cmd record brcmsmac:* &
  start network-manager
  wget http://<ip-over-wifi>/some-random-file
  <Ctrl+C>

wget did received some series of packets, with pauses in-between, but overal
the progress looks like it is stalled completely, there's almost no progress.

This is 3.16.3 kernel.  Note that reloading module after resume is not
sufficient (I'll try reloading whole brcm stack).

Thank you for your interest!

Hi Michael,

Did you have any opportunity to create a log file. Got a question from
someone else who got bad bcm4313 behaviour after a certain upgrade. Did
you have the same experience?

A kernel log (so no trace) of stalling interface might be useful so if 
you can provide that and put a marker in there where you believe it 
stalled that would be great.

Well, the wireless twiki has that info [1]. Regarding features the 
important ones that I know are still not there are 40MHz support, and 
power-save. The bcm4313 does not support 40MHz. Community contributions 
added ibss, and ap mode. For P2P and TDLS probably some changes would be 
needed although most of the legwork is done in mac80211.

That's past already.  I had several issues with wl driver,
and current issue is that even the latest (Aug-2014) version
of wl driver doesn't work with current kernel.  So I can't
really even compare wl and brcmsmac, -- in kernels < 3.16
brcmsmac does not work, but wl can't be compiled for 3.16,

Okay.  This turned out to be not so simple.

My initial attempt indicated that brcmsmac in 3.16 does
not work at all.  This isn't actually true - subsequent
attempts shows that it works.  I was ready to conclude
the problem is fixed (after transferring several gigs
of data over wifi, with tracing enabled or disabled,
after fresh boot or after reboot from wl-enabled kernel,
etc - it all worked.

Until I hit the same stall as I described initially, the
same which happened numerous times with kernel 3.12 ($subj).

After several mins of transferring it stalled.  But this
time (unlike with 3.12), it continued after about 30 secs.

So, while my initial test of 3.16 indicated the prob is still
here, at the same (or even worse) state, I can't really
reproduce it, at least in a reliable way.  There's something
wrong still, but at least current version is significantly
more useful than before (in a hope it wont stall at the
very wrong moment exactly ;).

There's one more difference between brcmsmac and wl -- with
wl, I see significantly better speed, -- it is about 5MB/sec,
while with brcmsmac it jumps between 2.0..4.5MB/sec (with
58..65Mbps connection rate in both cases).  Here's a typical
iwconfig output for brcmsmac version:

wlan0     IEEE 802.11bgn  ESSID:"mjt"
          Mode:Managed  Frequency:2.412 GHz  Access Point: 64:70:02:29:D9:30
          Bit Rate=65 Mb/s   Tx-Power=19 dBm

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:56355  Invalid misc:472   Missed beacon:0

I'll keep trying/testing various cases, in attempt to
understand what's going on.  For now, I can't provide the
requested traces (it wont be very useful, I guess).

BTW, are there other things not implemented in brcmsmac?
I see the module reminds about power management, what
does it mean?  Anything else missing?

Thank you!

Well, sorry about that. I did see the other messages fly by and noticed 
you were using the wl driver so assumed you were fine with that. 
Admittedly the brcmsmac got very little attention as all our resources 
were put on brcmfmac.

Ok. Let's put frustration aside and make an effort. So could you make a 
trace using trace-cmd utility. The log can get quite big. The brcmsmac 
driver needs to be built with CONFIG_BRCM_TRACING enabled. Please 
execute the following commands (assuming you use ubuntu with 
network-manager):

$ sudo stop network-manager
$ sudo insmod brcmfmac.ko
$ sudo trace-cmd record -e brcmsmac:*

In another terminal:

$ sudo start network-manager

The trace-cmd must be stopped using ctrl-c.

You might be a good politician :)  These are blames, quite strong...

Seriously. As you revisited this thread, I had quite some issues and
money loss after all this, -- after initially especially choosing a
model with a supported wifi card which turned out to be non-working,
which I tried to fix by buying a new wifi NIC (which didn't work
thanks to Lenovo), and which I finally broke due to usb wifi dongle
I used.

But that's all "poetry", the main source of my blames is you reaction -
your first reply was really ecoraging, I hoped we can have some solution
together (I have strong programming background, just not as good with
kernel and drivers as you).  But after your single reply, you never
spoke again until now.  That's 8 months.  _That_ is where my frustration
comes from.

And the actual facts are true - by now I have had 2 entirely different
devices (my original laptop which is now thrown away and another, given
by me by a friend because I needed something) - I dunno if that's
exactly the same wifi card or not (lspci output looks similar, and
this one is also bt/wifi combo), but they both doesn't work in a
quite similar way.  So, the driver doesn't work with 2 out of 2 devices
which I've seen.  Not a good statistics generally, but that's 100%
"hit" ratio for me.  So I really am curious if this driver works at
all.

I tested this "new" laptop with 3.16 kernel just briefly.  I may try more
complete analysis.  I can participate with the debugging/dumping (I already
mentioned my strong programming background - but I'm really not into drivers
and hardware internals).  So, basically, I'm all yours ;)  Not that I really
need this driver anymore (since I will avoid these cards like a plague, for

Hi Michael,

Thanks for your encouraging suggestions. I revisited the threads you 
referred to. In the boardflags it shows you have a bt+wifi card. It 
could be that is an issue. The brcmsmac supports other devices, ie. 
bcm43224/5 and the bcm4313 comes in a number of varieties. From what you 
tell here it seems you have trouble in rx path so I will look into that 
area if there is any specifically done for your variant of the bcm4313.

Hi Michael,

Thanks for your encouraging suggestions. I revisited the threads you 
referred to. In the boardflags it shows you have a bt+wifi card. It 
could be that is an issue. The brcmsmac supports other devices, ie. 
bcm43224/5 and the bcm4313 comes in a number of varieties. From what you 
tell here it seems you have trouble in rx path so I will look into that 
area if there is any specifically done for your variant of the bcm4313.

Regards,
Arend

Today I tried 3.16 kernel today too, just for fun (since this whole brcmsmac
thing looks not more like a non-working toy).  Now with another laptop and
the same broadcom wifi adaptor (BRCM4313 802.11bgn Wireless Network Adapter
rev 01) (because due to cracked usb port on my original notebook it does not
work anymore).

This combination (kernel & wifi) does not work at all.  Or, it is more jokish
than before -- the NIC works for ARP packets but nothing else, not even ping
or DNS or NTP.  I see the access point sending replies (to pings or dns), but
these replies are not shown by tcpdump on the laptop.  Even not all ARP packets
sent by the AP reaches the laptop.

So, I'm curious -- why this driver is found in regular section of kernel?
It looks like it should be in staging at least, or better yet, in a new section
titled "toy drivers" or something like this.  Does it work for any device at
all?

Tried kernel 3.14 with this device.  Still no go, the brcmsmac driver still
does not work correctly, it stalls as before.

On the other hand, I found out how to compile the proprietary driver for
3.10+ kernels, it requires some rather minor source modifications.

Re: BCM4313 & brcmsmac & 3.12: only semi-working?

[Michael Tokarev]

After some more unsuccessful digging with brcmsmac driver, I thought I'd
give wl driver a try.

Unfortunately it does not work with kernels > 3.8, so I tried with 3.2.

There, wl.ko built successfully, created eth1 device on load, and wifi
apparently works fine.  I transferred a few gigs in both direction, and
the signal is very stable at 65Mbps.  It worked for several hours.

Unfortunately, kernels before 3.9 has another problem on this laptop:
it is the battery life.  3.8 and older kernels draws battery much faster
(even without wifi enabled), this laptop lasts about 4 hours on battery
with 3.2 kernel, compared to more than 7 with 3.10 kernel.  I guess it
is the new ivy bridge pstates support introduced in 3.9.

I tried compiling wl.ko for 3.10 kernel, but unfortunately it doesn't
work there (after some minor tweaking of the source - I just commented
out procfs support) -- it does not find any devices.

So it looks like brcmsmac driver has a prob/bug, while wl driver works,
but wl doesn't work with more recent kernel.

It is still better than to use a separate usb dongle.  But it'd be
really nie to see brcmsmac driver just working without the need to
decide which don you want now: battery life or wifi (I'd vote for
both :)

Thanks,

Re: BCM4313 & brcmsmac & 3.12: only semi-working?

[Nikita N.]

Interesting post.
BTW, I have been debugging those issues too, in my case coming from
using bcm4313 under windows xp.
And actually found out the cause, at least in my case: every setup frame
*RETRANSMISSION* invalidates the whole setup connection process.
I dont know if its a bug into the winxp driver of into bcm4313 firmware,
all what I know is that setup fails if router RE-sends even just 1
frame, either with retransmission flag set, or a new one with different
seqnum.
Which in fact means, if the router is not close a couple of meters from
you (hotel,cafes,office,..) you cant connect, as router will inevitably
send at least 1 retransmission.
On the other hand, setup is always successful when a strict series of
1-only-1 setup frames is sent both sides: auth req/auth resp/asso
req/asso resp.

Personally I got used to that issue, and also I always bring with me a
secondary backup usb interface.. sorry, what to do? life is a continuous
workaround.. :P

Re: BCM4313 & brcmsmac & 3.12: only semi-working?

[Michael Tokarev]

So, I returned from my newyear trip.  There, I tried to use this my laptop
with many various wifi networks, in hotels, cafes and other places.  And
it never worked.

So I bought an usb wifi adaptor, some cheap old orient model, which worked
MUCH better than the built-in broadcom wifi. Except of 2 issues.

First, the antenna in this usb dongle is small, so signal quality isn't as
good as for the built-in adaptor with good antenna.

And second, which is much more severe, it is an external adaptor plugged
into an usb slot, so it isn't that easy as internal one, but it is very
easy to BREAK the usb slot.  Which is what I did while sitting in a cafe
and someone else walking by.  So now I've one usb port on my laptop broken
now (with very unpleasant large crack on the laptop "body") and the usb
wifi adaptor I bought is broken too.

I also tried to replace the internal wifi card with some non-broadcom
model, but the laptop refused to _boot_ while the card is inserted
(a so-called bios lock).

So the question stands: what is the way to actually use the internal
bcm card, without all those hassles I already encountered?

So far, the expirience was that anything with broadcom inside should
NOT be considered for a purchase, because the issues they gave you
costs much more than a price difference for a different model without
broadcom parts.

Thanks,

Capture file made with tcpdump is attached (gzipped).  I started the
capture with wlan0 disabled, next I  used `nmcli con up id "wifi mjt"'
to connect to the AP (named, obviously, "mjt"), and next I tried to
d/load a file from my website (86.62.121.231).  It d/loaded about 27Kb
and stalled.  Next I tried to ping the AP (192.168.88.65), which also
didn't work.

That's quite a typical behavour of this whole thing.  Sometimes it
lasts a bit longer, but that's rather unusual and it ends up stalling
anyway.

Is it worth the effort to try 3.13-tobe kernel here?  I browsed changes
in there made in drivers/net/wireless/brcm80211/ compared with 3.12, but
there aren't many changes related to the softmac version, and most
looks rather cosmetic.

Thank you very much for the help!

Nope. The brcm80211-dev-list is just a (hopefully) convenient way to get
your message to the brcm80211 driver developer within Broadcom. So it is
always best to Cc: the linux-wireless list as well.

Now about your card. I am not sure where to start, but can you dump
contents for following debugfs file:

/sys/kernel/debug/brcmsmac/bcma*/hardware

Also a capture file would be great so if you have wireshark or dumpcap 
you can add monitor interface and capture 802.11 packets from connect up 
until the stalls. Commands for adding/enabling monitor interface (ass 
root/sudo):

# iw dev wlan0 interface add mon0 type monitor
# ifconfig mon0 up

BCM4313 & brcmsmac & 3.12: only semi-working?

[Michael Tokarev]

Hello.

Got a Lenovo Thinkpad notebook with the following wifi card:

03:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)
	Subsystem: Broadcom Corporation Device [14e4:0608]
	Flags: bus master, fast devsel, latency 0, IRQ 17
	Memory at f1600000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [40] Power Management version 3
	Capabilities: [58] Vendor Specific Information: Len=78 <?>
	Capabilities: [48] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [d0] Express Endpoint, MSI 00
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [13c] Virtual Channel
	Capabilities: [160] Device Serial Number 00-00-24-ff-ff-fe-48-d2
	Capabilities: [16c] Power Budgeting <?>
	Kernel driver in use: bcma-pci-bridge

With 3.12 kernel, the device is recognized and it is possible to
connect to the access point and exchange some data.  In 3.10,
even connection (assotiation with the AP) was quite a bit
problematic, and packet exchange never worked).

However, after receiving a few packets (about 100 packets), the
interface almost stops receiving data, except a few packets once
in a while.  For example, when d/loading some file over wifi, first
part (very beginning) gets d/loaded fine, and next d/load stalls,
with Rx counter of the card not changing.  Terminating the process
makes the counter to increase by one or two.

Stopping and re-starting the interface in NetworkManager makes
it go again, also for just about 100 packets, till it stalls
again.

Sometimes it works longer, say, 500 or even 1000 packets, but
at the end it stalls anyway.

Here's a typical iwconfig output:

wlan0     IEEE 802.11bgn  ESSID:"mjt"
          Mode:Managed  Frequency:2.412 GHz  Access Point: 64:70:02:29:D9:30
          Bit Rate=1 Mb/s   Tx-Power=19 dBm
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=56/70  Signal level=-54 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:84  Invalid misc:13   Missed beacon:0

(Note the bitrate of 1Mbps: the AP is pretty much capable of
running at 54Mbps, and actually my smartphone, when used in
exactly the same place, goes at full 54Mbps just fine.  The
signal conditions are very well in here, AP is about 15 meters
away, stright visible.  When I force-reconnect it, it displays
some more sane value here for a few moments but drops to 1mbps
anyway).

Here's some dmesg output when I start/stop wifi network and
try to d/load something:

The same notebook with the same wifi card works just fine under
windows (both windows 7 and 8), demonstrating stable reliable
about-54Mbps connection.

Is there any hope to get this device working under linux?

I can re-build kernels and stuff, enable debugging etc, -- that's
no problem, but I've really limited time.

I purchased this notebook especially to be used when travelling,
to be able to access to my office/work network over hotel wifi,
I plan to have a trip starting Jan-2.  After figuring out that
it doesn't quite work as I'd expect it to do, I purchased another
wifi card, just to face another issue: it my notebook refuses to
_boot_ while that card is inserted! (it was a completely new
and unexpected "feature", now I know what it is, and will avoid
lenovo and HP notebooks in the future), -- so I returned the card
back.  But now I'm again without wifi, and I can't return the
notebook...

P.S. I tried to find archives of brcm80211 list, or a way to
subscribe to it before posting, but found neither.  Are there
archives?

Thanks,
