You need to remove the module before loading it with new options.

Try
# rmmod b43
Before the modprobe command.

You're right!  I tried it here too:

# modprobe -r b43
# modprobe -v b43 options hwpctl=0
insmod /lib/modules/4.4.39-gentoo/kernel/net/wireless/cfg80211.ko.gz 
insmod /lib/modules/4.4.39-gentoo/kernel/net/mac80211/mac80211.ko.gz 
insmod /lib/modules/4.4.39-gentoo/kernel/drivers/ssb/ssb.ko.gz 
insmod /lib/modules/4.4.39-gentoo/kernel/drivers/net/wireless/b43/b43.ko.gz 
qos=0 options hwpctl=0

However, it doesn't seem to report this when I look at the sys entry, just 
like yours:

$ cat /sys/class/net/wlan0/power/control 
auto

Even if power control reported as auto (perhaps some other kernel setting 
imposes this) as long as the power control setting (0 or 1) help your problem 
then use it.  If it is ineffective remove it and let the kernel do its own 
thing.

Did you increase verbosity and have you checked your logs and dmesg to see if 
there is anything reported when connection is lost?

Hello,
It returns alway "auto".

On the official Systemd documentation, I see that there is a new
directory to say which modules load, but to change options, it's always
with modprobe.

I tried to modified the option on a command line, but, it's stay at "auto" :
# modprobe b43 options hwpctl=0
# cat /sys/class/net/wlp36s0b1/power/control
auto
# modprobe b43 options hwpctl=1
# cat /sys/class/net/wlp36s0b1/power/control
auto
# modprobe b43 options hwpctl=off
# cat /sys/class/net/wlp36s0b1/power/control
auto

What is wrong ?

I really think that I use this module :
# lsmod
Module  Size  Used by
x86_pkg_temp_thermal 4663  0
kvm_intel 148031  0
b43   385652  0
kvm   309648  1 kvm_intel
irqbypass   2616  1 kvm
sha1_generic3067  0


For help, this is my kernel options about its :
# grep -i "b43" /usr/src/linux/.config
CONFIG_B43=m
CONFIG_B43_BCMA=y
CONFIG_B43_SSB=y

Try setting:

 I have a wireless card :

 Globally, the card works fine. I use wpa_supplicant. I have a systemd
 service to start the connection when I want. The DHCP client works fine
 too. etc. All is right.

 But, because there is always a "but", After a certain quantity of
 downloaded data, the card's stopping to work fine. I can't receive
 anything. I need to stop an restart the systemd service.

 I herd that there is many problems with Broadcom wireless devices
 because the driver is only based on reverse engineering.

 That is the reason ? And there is a solution for this kind of problem ?

 Thank you very much !

Hello !

Thanks for help. But for now the result of your cat command returns "auto".
I created b43.conf in /etc/modprobe.d/ with same permissions than others
files in the same directory with content:
options b43 hwpctl=0.
I restarted.
The cat command returns "auto" again.

What is wrong ?

Thanks again !

[snip ...]

The above parameter is the only one I see related to power management.  So, 
let's see what the card is configured to use at present:

cat /sys/class/net/wlp36s0b1/power/control

The default setting would be off and since this parameter is specified as an 
integer it is likely to be 0.  There is also a possibility of it being set at 
'auto'.  In any case you can try switching this on, to see if it is makes any 
difference, or if it is set at 'auto' force it to off.

I see you are running systemd.  I am not well versed with it, so others will 
hopefully chip in to correct me.  On a normal Gentoo system with openrc I 
would use this file to set options:

 /etc/modprobe.d/b43.conf

So create it and add in it:

options b43 hwpctl=1

to switch power management on, or:

options b43 hwpctl=0

to force it off.

Then unload/reload the module using modprobe, or reboot and see if with either 
setting the problem goes away.

PS.  I am using the same module, but with a different card.  I noticed on mine 
I had set qos=0 for some reason.  I must have found this advice somewhere on 
the interwebs and set it so.  You may want to try this too to see if it makes 
any odds.

PPS.  You may also want to increase verbosity in the logs in the first instance 
to see if something is reported as a result of the fault you are getting.  Use 
this setting:

options b43 verbose=3

to increase verbosity.

I don't know what problems are being reported on the model you are using, but 
previous models were experiencing problems with power saving.  Use modinfo to 
find out what power saving parameters the module has and try disabling these, 
in case power management is the cause of the interruptions you are 
experiencing.

[gentoo-user] Broadcom wireless problem after a certain time

[Hogren]

Hello,

I write to the list for a little strange problem.

I have a wireless card :
# lspci |grep -i 802
24:00.0 Network controller: Broadcom Corporation BCM43228 802.11a/b/g/n


Globally, the card works fine. I use wpa_supplicant. I have a systemd
service to start the connection when I want. The DHCP client works fine
too. etc. All is right.

But, because there is always a "but", After a certain quantity of
downloaded data, the card's stopping to work fine. I can't receive
anything. I need to stop an restart the systemd service.

I herd that there is many problems with Broadcom wireless devices
because the driver is only based on reverse engineering.

That is the reason ? And there is a solution for this kind of problem ?

Thank you very much !

Hogren
