Description Forgotten User Drfk9mafMw 2006-11-04 11:51:16 UTC
After switching off my internal ipw2100 when not needed in order to save on battery life, knetworkmanager doesn't seem to reactivate the NIC and re-scan for present wireless networks when the card is switched on again. 

The card itself works and I can manually scan with "iwlist eth0 scan".

Killing knetworkmanager and restarting it solves the issue. Since this behavior has already been the same for 10.1, too, I would suggest to include a manual "Search for Wireless Networks" option in the NetworkManager frontends. Having to kill the applet is not very elegant :)

Did you check whether it is the same when using GNOME and nm-applet?
Comment 2 Forgotten User Drfk9mafMw 2006-11-06 09:14:53 UTC
No, I didn't since I very much prefer KDE. But considering the fact that killing the applet only and restarting it solves the issue, I would assume that the problem is caused by this very applet and not the underlying NetworkManager.

This bug is totally reproducible on KDE and anybody with a laptop and GNOME running could try if its also the same here.

I will try to have a look at it later but currently I have no time, sorry.

Daniel, this looks like a duplicate of bug #216495.

Also, see bug #207899 and bug #216558 for details.

Comment 5 Forgotten User Drfk9mafMw 2006-11-08 08:58:20 UTC
Yes, you could be right! I find a lot of the experienced behavior in the mentioned bugreports! Let's now see how the beta2 will perform :)
Comment 6 Tambet Ingo 2006-11-08 09:02:32 UTC
Could you attach your NetworkManager logs (/var/log/NetworkManager) here please and add information roughly when you added the ipw2200 module back?
Comment 7 Tambet Ingo 2006-11-08 09:25:58 UTC
Also, can you please just try to run nm-applet even if you prefer KDE, to debug this issue? From your comment #2, it actually sounds more like an applet problem if killing it and then restarting makes things work - it shows that NetworkManager knows about the device and the applet didn't catch the signal when it was added.
Comment 8 Forgotten User Drfk9mafMw 2006-11-08 09:40:38 UTC
Request #6 I will definitely try to fulfill this evening and send the log. I am extremely busy at work, so please be patient. 

#7 I have tried yesterday but I couldn't get YAST to fire up the Software Management Module. After >2hrs syncing time with errors in between I gave up on installing the gnome applet from factory... That Package Management system is horribly broken, I tell you.

Also it seems to me that there is no laptop to your availability at Novell or SuSE? The NetworkManager and its applets haven't really improved a lot since 10.1 albeit the apparent bugs... I promise that as soon as I win a Lotto Jackpot I will donate one so that you can do some basic testing yourselves, too.
Comment 9 Timo Hoenig 2006-11-08 09:54:26 UTC
Daniel, no need to get offensive.  If you would like to see this issue fixed, please go ahead without such comments.

[ We have enough hardware, please spend your money otherwise.  However, if the price is not money but a time machine, we are happy to accept it. ]
Comment 10 Forgotten User Drfk9mafMw 2006-11-08 10:21:22 UTC
First of all, you should be equally -- if not more -- interested in squashing bugs :) Secondly, if this sounded so offensive to you, then pls accept my apologies, it wasn't meant to be so. (But you must understand that I am seriously doubting the readiness of the package management system. Networkmanager works flawless in comparison to that.)

You will get the log tonight and I will download beta1-CDs in order to test with the gnome applet.

And yes, most of the time it seems to me that this is NOT a problem of NM itself but only the applet. Is there a CLI to the NM so that I could verify?

BTW a time machine is welcome here, too. I am doing my best to hunt down stuff but I can not spend (a lot of) my time on testing during office hrs.
