Yesterday I installed Alpha 7, it's the first time I installed an openSUSE 10.3
version at all. As openSUSE 10.3 ships the new mac80211 subsystem, I tried to
make the 'Intel PRO/Wireless 3945ABG' device of my ThinkPad T60p work, using
the iwlwifi driver from intellinuxwireless.org, which was written for the
mac80211 subsystem.
So I got the iwlwifi driver (version 0.1.8) from http://intellinuxwireless.org/ 
together with the microcode image (version iwlwifi-3945-ucode-2.14.1.5). It 
compiles without errors and loading the iwl3945 kernel module works fine and 
brings up the 'wlan0' interface. Well, only the wlan LED on my ThinkPad does 
not light!
Now the device shows up in Yast too, and it seems like it can be configured as
usual. But actually it doesn't work, because the settings are not written to
disk. Every time I launch the Yast network device settings section again, my
WLAN device appears unconfigured. Looking in /etc/sysconfig/network reveals,
that no configuration file for the wlan devices is ever created. I nearly tried
all possible settings in Yast by now, just to see if it will save the
configuration to /etc/sysconfig/network/ under any circumstances, but that
never happened. In contrast, the settings of my wired e1000 device are written
to /etc/sysconfig/network/ifcfg-eth0 with no problem.
Next I tried copying the configuration of my wlan device from my openSUSE 10.2
configuration, to see if Yast will recognize and read it, at least. On openSUSE
10.2 the configuration file of my wlan device had the filename
ifcfg-wlan-id-00:10:20:30:40:50 (where 00:10:20:30:40:50 is not my real mac
address, I just don't want to post it here). Copying that file to
/etc/sysconfig/network on openSUSE 10.3, won't let Yast detect the
configuration, the device still appears as not configured in Yast. An
'rcnetwork restart' won't use the configuration, too. Here the output:
wlan0 device: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev
02)
              No configuration found for wlan0                       unused
Well, renaming 'ifcfg-wlan-id-00:10:20:30:40:50' to 'ifcfg-wlan0' causes the
configuration to be recognized by ifup and rcnetwork start/restart will
successfully establish a connection with my access point. Anyway, even now my
wlan0 device still doesn't show up as configured in Yast.
I also tried the 'User Controlled with NetworkManager' Option, but this way, I
can only connect using WEP encryption. WPA doesn't work with NetworkManager.
Anyway, since I make heavy use of SCPM, NetworkManager is not really an option
for me.
I come to the conclusion, that this is a YaST problem, because manually
creating the ifcfg file and placing it in /etc/sysconfig/network works well.
Next I did a 'tail -f /var/log/YaST2/y2log' to find out, why Yast doesn't write
down the configuration for the wlan interface, but for the wired interface. I
append the complete output as a file to this post. Interesting are the lines
where it says:
2007-08-05 16:34:27 <1> myhost(21379) [YCP] NetworkModules.ycp:220 No changes
to netcard modules -> nothing to write
2007-08-05 16:34:27 <1> myhost(21379) [YCP] NetworkDevices.ycp:651 No changes
to netcard devices -> nothing to write
I hope this information helps to track down the problem.
Regards,
Jörg
