Description Ivan Zakharyaschev 2014-12-23 19:39:21 MSK
I've tried regular-wmaker-20141217-x86_64.iso on a Dell Latitude. Thw wifi driver wasn't loaded and no wifi network adapters were available.

altlinux-7.0.4-simply-x86_64-live-dvd5.iso doesn't have this problem.

Please specify kernel-modules-* and firmware-* packages included in environment that works for you; TIA.
Comment 2 Ivan Zakharyaschev 2014-12-24 13:16:24 MSK
Ok, I'll take a look right now.

Another thought: perhaps, in regular-wmaker some service should be started manually to initialize the network drivers?

Perhaps: service network start

I haven't tried that.

I suspect (not sure) that kernel-modules-bcmwl-std-def-6.30.223.141-alt2.199200.1 is the thing that make WiFi work.
Comment 5 Michael Shigorin 2014-12-24 15:25:58 MSK
Weird: firmware packages are basically the same (the only broadcom-related one present in Simply and missing in regular-wmaker is firmware-crystalhd which is related to video decoding I believe); k-m-bcmwl and -staging are also present but it doesn't even matter as brcmsmac.ko is sitting in kernel-image-std-def.

This is definitely not about services per se.

Try getting to the point when "modprobe brcmsmac" on regular-wmaker with any differing packages installed gets you wlan0 interface (putting success/fail dmesgs aside might be useful either).
Comment 6 Ivan Zakharyaschev 2014-12-24 15:37:38 MSK
Thanks for the comment!

"This is definitely not about services per se."

Ok... I even used to think that in SimplyLinux NetworkManager might care about loading the network drivers, and since NM is missing in regular-wmaker I had no WiFi... So, that's not the right way to explore.

Will try to look at dmesg side by side next.

It's rather udev's responsibility but it's the same in both cases.

After that the interface is listed by "ip addr" (but not by "ifconfig"). Probably, if I configure it correctly (in etcnet or after installing NM), it will work.

The confusing part is that the driver is not loaded automatically and not shown in the list of interfaces.

Comment 15 Ivan Zakharyaschev 2014-12-24 19:38:20 MSK
iwlist scan gives results. So wifi works.


It's not quite clear how to configure it easily. (Probably, manually editing etcnet is the way.) alterator has a broken WiFi configuration (at least, in this setup, without dbus): it can't correctly copy the name of the network and has other problems. NetworkManager is not installed.

So, it seems that it is possible to configure WiFi in this distro after installation (without network access, but knowing the correct module name).

A problem was to learn the correct driver name in this situation, because it wasn't loaded automatically.

This *might* be related (via rfkill)...

Indeed; NM (or rather polkit) won't work without systemd-logind operable though, see also http://altlinux.org/sysvinit; but etcnet-based setup should work just fine (manual or via alterator-net-wifi), or say connman-based one.

Now *that* is strange and worth investigating IMO.  dell-wmi.ko is included into kernel-image-std-def either, no idea on what could be the culprit so far.
Comment 17 Ivan Zakharyaschev 2014-12-26 11:55:06 MSK
Just for info: The behavior in altlinux-p7-wmaker-20141212-x86_64.iso is the same: module not loaded, wlan0 not present after booting the Live system.
Comment 18 Ivan Zakharyaschev 2014-12-26 12:12:43 MSK
Perhaps, /lib/systemd/system/systemd-udev-trigger.service does this in Simply Linux, and there is no analogue in regular-wmaker...

/sbin/udevadm trigger --type=devices --action=add

seems to make the interface appear in regular-wmaker. (Under a different name though: eth1)

Correction: in starterkit-wmaker.

Another driver is used: wl . brcmsmac was not loaded.
Comment 21 Ivan Zakharyaschev 2014-12-26 12:29:07 MSK
No, everything I wrote above about udevadm is not correct because that was not a clean experiment: I did it after modprobe -r brcmsmac. After a clean boot, this doesn't make the wireless appear.
Comment 22 Ivan Zakharyaschev 2014-12-28 20:28:41 MSK
In the wmaker system (tested in starterkit), after the boot:

udevadm trigger

makes no difference: no wlan0 interface.

But if I do:

modprobe -r bcma
udevadm trigger

then the wifi interface appears (under the name eth1). "wl" driver is used, "brcmsmac" is not used and not loaded.

So, proably "bcma" somehow gets into the way for correct initialization of the wifi drivers...
Comment 23 Ivan Zakharyaschev 2014-12-28 20:30:23 MSK
But "bcma" is not a problem in Simply Linux 7.0.4 (it is listed above among the moules loaded).
Comment 24 Michael Shigorin 2014-12-28 21:32:13 MSK
Ugh.
Comment 25 Ivan Zakharyaschev 2014-12-29 02:22:05 MSK
Here they also observe similar two variants of modules for a WiFi card: wl vs bcma -- https://bugzilla.altlinux.org/show_bug.cgi?id=29270#c0 .

Here they had problems with bcma, which were gone after blacklisting it -- https://bugzilla.altlinux.org/show_bug.cgi?id=30229 .

The only strange thing is that SimplyLinux 7.0.4 seems to use bcma and brcmsmac successfully, but starterkit-wmaker and regular-wmaker can't do this anymore.

Это цитата из 
https://bugzilla.altlinux.org/show_bug.cgi?id=26854#c1 . Это несколько ссылок на возникавшие проблемы такого рода в этой области.

Какой драйвер из двух работающих лучше, я не смогу судить (пока).

И как так получилось, что грузится bcma и мешает дальше грузиться и тому (brcmsmac), и другому (wl), я не понимаю. Менялся состав модулей и списки в blacklists (в результате они плохо друг другу соответствуют)?

If this machine is interesting for some experiments with these drivers, it is with me.

But I don't remember well all the details. (Well, I see: it was fine with a p7 distro, which I'm using now, but was broken with some newer regular-* distros.)
