--- Comment #5 from Harald Koenig <koenig@xxxxxxxx> 2010-02-26 20:34:24 UTC ---
(In reply to comment #3)
The ifup/ifdown works as expected [3].

ifup only works for you because you are lucky enough to have
/sys/class/net/wlan0/wireless
this /sys/ entry is missing for my setup since last update, otherwise ifup
still would correctly work.

so this boils down to: why did /sys/class/net/wlan0/wireless vanish with that
last update...
I'm happy to change my configuration if I'd know what to change...


# uname -a
Linux dolby 2.6.27.42-0.1-default

*this* is the full output of [my] uname -a (showing e.g. x86_64):

harald > uname -a
Linux harald 2.6.27.42-0.1-default #1 SMP 2010-01-06 16:07:25 +0100 x86_64
x86_64 x86_64 GNU/Linux



and one more bit of information about that "weak-updates" kernel module:



harald > rpm -qf
/lib/modules/2.6.27.39-0.2-default/updates/drivers/net/wireless/iwlwifi/iwlagn.ko
compat-wireless-stable-kmp-default-2.6.20091112_2.6.27.39_0.2-1.3

harald > rpm -qi
compat-wireless-stable-kmp-default-2.6.20091112_2.6.27.39_0.2-1.3
..
Install Date: Tue Feb 23 01:10:04 2010
Build Date: Tue Dec 1 21:19:42 2009
Distribution: home:Lord_LT / openSUSE_11.1_Update

hmmmmmmmm......


so I removed compat-wireless-stable-kmp-default (and
compat-wireless-kmp-default) and now I'm using

harald > /sbin/modinfo iwlagn| grep filename
filename:
/lib/modules/2.6.27.42-0.1-default/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko

harald > rpm -qf
/lib/modules/2.6.27.42-0.1-default/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko
kernel-default-2.6.27.42-0.1.1


and guess what::::

harald > ll /sys/class/net/wlan0/wireless/
total 0

hoooray !!!

btw. both iwlag drivers report the same version in kernel msgs:
1st the "bad" driver:

Feb 26 00:02:04 harald kernel: iwlagn: Intel(R) Wireless WiFi Link AGN
driver for Linux, 1.3.27ks
Feb 26 00:02:04 harald kernel: iwlagn: Copyright(c) 2003-2009 Intel
Corporation

and now yours which gives a few more msgs/infos:

Feb 26 21:14:38 harald kernel: iwlagn: Intel(R) Wireless WiFi Link AGN
driver for Linux, 1.3.27ks
Feb 26 21:14:38 harald kernel: iwlagn: Copyright(c) 2003-2008 Intel
Corporation
Feb 26 21:14:38 harald kernel: iwlagn: Detected Intel Wireless WiFi Link
4965AGN REV=0x4
Feb 26 21:14:38 harald kernel: iwlagn: Tunable channels: 13 802.11bg, 19
802.11a channels



anything I (our you) can do about the trouble with the iwlagn from
"home:Lord_LT / openSUSE_11.1_Update" ?

this again one of my rants about OBS: neither
"http://software.opensuse.org/search"; nor the repository url give any pointer
or hint where or how to report bugs/problems!
bugs just don't exist (but unfortuneately that doesn't make them go away;-)
IMHO that's really pitty...



I guess, now you can close the bug again ?!?

and thanks for listening and asking ;o)
