In my case, I have already logged into the KDE Desktop before the wireless is even activated. Checking dmesg, I get the following result: [ 1.953658] iwlwifi 0000:03:00.0: irq 40 for MSI/MSI-X [ 122.909870] iwlwifi 0000:03:00.0: loaded firmware version 9.221.4.1 build 25532 During the last two days I have been trying to find out the exact cause and if systemd is really to blame. Based on the changelogs I noticed that now udev is leaving the loading of the firmware up to the kernel. However this seems to have the above effect. When systemd is compiled however with "--with-firmware-path=/usr/lib/firmware", then the system behaves as expected and the wireless is up and running before the display manager becomes active. In this case dmesg shows: [ 9.816766] iwlwifi 0000:03:00.0: irq 40 for MSI/MSI-X [ 9.899872] iwlwifi 0000:03:00.0: loaded firmware version 9.221.4.1 build 25532 As said I am not sure if this is a kernel issue or that we should keep the ability to load firmware within udev.

Do this means is possible to re-enable it, also if we are running a kernel which is not yet ready with this, then we need this enabled. When we get the green light that the kernel can handle it, then we can drop this. Maybe Jiri knows more. @Jiri, can you please check that the kernel firmware part works as expected and we can drop the firmware loading from udev or at least us know the status of this from the kernel point of view? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Christian,

So you mean that the network only becoming available after the desktop is loaded, is the right behavior ?? If that is the case, then I guess you and I have quite a different opinion about a working desktop. How would you expect that people would authenticate against an Active Directory/LDAP/Kerberos environment, if there is no network ??

It seems that at this moment the kernel is not ready for this and definitely doesn't support it the right way. Until that is fixed, this would be the only way to restore the correct functionality.

That you might not suffer from this, means that you are just lucky but don't rule out other users !!

The network interface comes up not after the desktop comes up, but after NetworkManager does.. driver autoload --> request_firmware --> interface up by NM/ifplugd.. the desktop has nothing do with this. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I guess that I don''t have to explain it again. At this moment, my wireless network comes up after the KDE desktop is loaded. Alternatively I can also watch for a couple of minutes at the login screen of KDM in order for the Kernel to decide that the firmware should be loaded. In the logs attached to this bug, it is clearly to see that the kernel takes extremely long to load the firmware and based on that I fully support Robert that currently the kernel doesn't support this loading correctly. Maybe it depends on what firmware is required to be loaded and maybe for another wireless card it works, but on my system the kernel firmware loading heavily sucks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I agree and anyways firmware loading from udev has been enabled already in Factory.
