 |
|
Hello,
I run Gentoo on a Hp Probook 640 G1 equipped with a Broadcom Corporation BCM43228 wireless device. Most of the time it is possible to get good traffic through the wireless interface.
But once and a while it losses connection without a specific reason. Sometimes it is even not possible to establish a proper connection at all. I searched on google a lot without finding a solution. But I learned also that the Broadcom BCM43xxx are causing a lot of linux users a headache.
My kernel (4.1.12 version) is using the b43 module.
Who wants to take the challenge with me, to find a solution in order to make the Broadcom BCM43228 working stable within Gentoo Linux.

GenHeDi ...
Not enough information to point at a probable cause ... but from the fact that its intermittent I'd probably attribute the issue to the fact that wireless is radio (with all that implies).
Anyhow, please provide details of your setup ... and the output of the following (where 'wlan0' is whatever your interface happens to be named):
| Code: | # iw dev wlan0 station dump
# iw dev wlan0 get power_save
# iw reg get
# awk '/(WEXT|(MAC|CFG|NL)80211)/' /usr/src/linux/.config
# modinfo b43 |
It might also be worth enabling debugging in wpa_supplicant, and log it.
| /etc/conf.d/net: | | wpa_supplicant_wlan0="-Dnl80211 -dd -f /var/log/wpa_supplicant.log" |
Also, if the issue occurs, besides a 'station dump', the output of 'iw event -f' would be useful (you'll have to leave it running for a while, and/or redirect the output to a file).

By the way, following questions:
My /etc/conf.d/net
| Code: |
cat /etc/conf.d/net
config_enp0s25="dhcp"
config_wlp2s0b1="dhcp"
modules="wpa_supplicant"
|
And from the wpa_supplicant wiki:
| Quote: |
Enable Logging
By default, wpa_supplicant performs very little debugging without the debug flag enabled.
root #USE="debug" emerge --ask wpa_supplicant
FILE /etc/conf.d/netfor usage with the Setup for Gentoo net.* scripts
| Code: |
modules_wlan0="wpa_supplicant"
wpa_supplicant_wlan0="-Dnl80211 -d -f /var/log/wpa_supplicant.log"
config_wlan0="dhcp"
|
|
| Code: |
emerge -pv wpa_supplicant
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] net-wireless/wpa_supplicant-2.4-r3::gentoo USE="dbus hs2-0 qt4 readline ssl -ap -eap-sim -fasteap -gnutls -p2p (-ps3) (-selinux) -smartcard -tdls -uncommon-eap-types -wimax -wps" 0 KiB

- Is it necessary to replace the _wlan0 part with my _wlp2s0b1?
- Is it necessary to extend the modules line to modules_wlp2s0b1?
- Do I need to emerge the wpa_supplicant with "debug" use-flag?

GenHeDi ... yes.
| GenHeDi wrote: | | - Is it necessary to extend the modules line to modules_wlp2s0b1? |
Yes, without it this would be also be set for enp0s25. So, to be more explicit:
| /etc/conf.d/net: | modules_wlp2s0b1="wpa_supplicant dhcpcd"
modules_enp0s25="dhcpcd" |
| GenHeDi wrote: | | - Do I need to emerge the wpa_supplicant with "debug" use-flag? |
No, in fact there is no 'debug' useflag on wpa_supplicant any longer, I had requested (via a bug report) that DEBUG_FILE be set by default, it doesn't add much in terms of code but it means that users with issues don't have to enable the useflag and re-build simply to use '-dd -f'.
The output above seems ok ... but generally the advice with b42 is to disable hwcrypt (at least it was ... not sure what the current status is ITR).
| Code: | | # echo "options b42 nohwcrypt" > /etc/modprobe.d/b42.conf |
If you post with output as and when the issue occurs then I might get a better idea of what's happening.

Is it possible that you mean b43 instead of b42?

| Code: | | echo "options b43 nohwcrypt" > /etc/modprobe.d/b43.conf |
Results in a non working wireless adapter (after a restart of my computer).
After a look in dmesg I found following line:
| Code: |
[ 15.932047] b43: `' invalid for parameter `nohwcrypt'
|
Is it possible that you mean:
| Code: | | echo "options b43 nohwcrypt=1" > /etc/modprobe.d/b43.conf |
Regards

GenHiDi ... yes ... the above 'modinfo b43' states the parameter is an integer '(int)'
| Code: | | parm: nohwcrypt:Disable hardware encryption. (int) |
In my case, ath5k, its boolean '(bool)'.
| modinfo ath5k | egrep '^parm.*nohwcrypt': | | parm: nohwcrypt:Disable hardware encryption. (bool) |
I do wish if different drivers used the same parameter they would be consistent in how it was enabled.

Oke, I have put everything in place according to your description. First result of the wpa log file is shown below (last bunch of lines).
The connection is not dropping connection yet, but is not fast at this moment. The forum site was build slow (the emoticons were first only text hyper links and than one by one becoming pictures)

GenHeDi ...
ok, I need to see the output of 'iw dev wlp2s0b1 station dump' and 'iw event -f' during this same period (the latter may take some time to generate output). Also, is there anything in dmesg ... specifically related to b43, or (MAC|CFG|NL)80211.

Luckely during this data collection session I lost connection. I played on youtube a long song and suddenly the music stopped. I hope this output give you some information.
I gained a new connection by ifconfig wlp2s0b1 down/up.

GenHeDi ... here's what (little) I can tell you ...
| GenHeDi wrote: | | Code: | | wlp2s0b1 (phy #0): CQM event: unknown event |
|
CQM is "connection quality monitor", such an "unknown event" probably means a buggy driver, if it were protocol related it would probably know, and report, the cause.
The dump shows some level of failed TX (transmissions), which we can attribute either to the driver (bug), or radio interference. When you get transmission failures the bitrate drops, higher bitrates translate to tighter packed frames (and so more chance of collision/failure) so stepping down is normal/expected ... though, as you noticed, it effects throughput.
So, we know something is wrong, and given the 'unknown event' I'd suspect it's either hardware, or the driver (rather than general radio interference).
| GenHeDi wrote: | | I gained a new connection by ifconfig wlp2s0b1 down/up. |
If you're runing wpa_supplicant from /etc/init.d/net.wlp2s0b1 you shouldn't need to, wpa_cli should be running and will call /etc/wpa_supplicant/wpa_cli.sh when DISCONNECT is registered. Does it not automatically reconnect (if not this is another hint at a driver bug).

| Have you tried cutting proprietary broadcom firmware with b43-fwcutter? That helped me on fedora once, not long time ago. I had exactly the same problem (connection dropped after a while) |

@khayyam
Yes, I'm running wpa_supplicant from /etc/init.d/net.wlp2s0b1 and it is definitely not always reconnecting automatically. I checked /etc/wpa_supplicant/wpa_cli.sh and it is available.
The only way to reconnect in current situation is to execute ifconfig wlp2s0b1 down/up. Although sometimes the connection get suddenly slow and the browser is waiting on traffic from the visited site. I think that during those moments it is reconnecting automatically, but definitely not always.
@NForce
Nope, at this moment I'm using the standard b43 driver delivered with the Gentoo installation. Cutting proprietary firmware is new stuff for me, is it possible to explain some steps to follow?
Regards to all

GenHeDi ... if you get 'disconnected (by AP) reason:' then it should automatically attempt to reconnect, you'll see this in 'iw event -f' (as in the above) ... are you saying that this occurs but no connection is established? I'm not really sure I understand why you think its not doing this (even if irratically). Please try adding the following to the global definitions in wpa_supplicant.conf
| /etc/wpa_supplicant/wpa_supplicant.conf: | eapol_version=2
fast_reauth=1 |
BTW, rather than 'ifconfig iface up/down' you can do 'wpa_cli reconnect'.

According with the b43 page, b43 only support the BCM43228 device with the PCI-ID 14e4:4359 , unless the chip ID do not correspond to it's PCI-ID.
So, the output of the command
will help to be sure if b43 support this Broadcom device.

The deauthentication reason is 2. According with the page Linux WiFi: Deauthenticated Reason Codes, the client is authentificated but not authorised. The problem can come from the AP router configuration and/or the client permissions.
I have seen Wireless connects, then disconnect as Solved problem for reason 2 deauthentication by changing the AP configuration to only accept Wpa authentification encryption.

I had a look in my router (a TP-Link TL-WR1043ND) and I have following options:
WPA/WPA2 - personal (recommended) >> is selected (also possible to select WPA/WPA2 - enterprice)
- version > automatic (recommended) >> is selected
> WPA-PSK
> WPA2-PSK
- encryption > automatic (recommended)
> TKIP

It is an assumption, not based on data. I was just looking at the screen of the browser and not looking into log-files. I apologize for the fact that I might have put you on the wrong track.
Fact is that my connection was frozen while collecting the data above.

Logicien ... it can happen if there is a breakdown in transmission (lost beacon) between the AP and the STA.

I don't think this is the case, the above suggests the issue is not on the protocol level. These things are always very difficult to debug because radio is inherently prone to environmental pollution. So, it *could* in fact be anything (ie, the Faraday effect, location, weather, solar flares, heavy traffic in the same spectrum from adjacent AP's ... you name it), but I would suspect the hardware/driver based on the above (and assuming GenHeDi doesn't have similar issues with other clients/OSes/machines).
