KNetworkManager: after 2-3 hours the wireless connection won't work anymore until reboot

Binary package hint: knetworkmanager

  Hello,

  at home I have a hidden wireless network. I used to connect to it from my Toshiba Sattelite M50 laptop using KNetworkManager on Kubuntu 8.04. There used to be no trouble with it, but recently some weird thing started happening (I guess, it all began after some recent upgrade, however I don't remember exactly when).

  After about 2 or 3 hours of stable connection, KNetworkManager suddenly will disconnect and try to connect again. And it won't work. While it's still working, I can display a list of all wireless networks in the sensitivity (there are quite a lot around here). After it does this weird stuff, no list is there. And it won't connect to the wireless network anymore.

  The wired network, however, works just fine with KNetworkManager even after that. Right now, for example, I'm connected to my router with a LAN-Cable, because WLAN won't work again.

  After a reboot WLAN works again, but again it lasts only a few hours till the next drop.

  Thank you for your help in advance!

Thank you for taking the time to report this bug and helping to make Kubuntu better. The KDE3 version of KNetworkManager has been discontinued by its original authors. This unfortunately means that there will be no more bugfix releases, and updates in general will be limited to those fixing security flaws.

While we cannot fix your bug, the good news is that the applet has been totally rewritten for KDE4 in the upcoming Kubuntu 9.10 release. There is a good chance that this bug is no longer an issue with the new applet. If you find any similar or new issues with the applet included in Kubuntu 9.10, we would politely ask you to file them as new bugs against the "plasma-widget-networkmanagement" package.

Thanks in advance for your cooperation and understanding.
