KNetworkManager Fails to "detect" wireless card

[Andreas Wenning]

Binary package hint: knetworkmanager

KNetworkmanager stopped "detecting" wireless card. Only the part about "Wired devices" appears, the part about "Wireless" has disappeared.

I have no problems connecting to wireless networks using iwconfig; and wlassistant works without any problems.

Distro: Kubuntu feisty beta
Uname: Linux andreas-laptop 2.6.20-14-generic #2 SMP Mon Apr 2 20:37:49 UTC 2007 i686 GNU/Linux
KNetworkManager: 0.1-0ubuntu11

The problem might have occurred with the last package update as I don't restart the KNetworkManager that often. A restart of the system has no effect.

Any further information needed?

Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the contents of your '/etc/network/interfaces' file? Thanks in advance.

/etc/network/interfaces

Output of ifconfig

Removing the last to lines from /etc/network/interfaces fixes the problem.
/etc/network/interfaces is auto-setup by kubuntu, haven't changed anything until now; but seems like some sort of unreliability in the Knetworkmanager wireless detection compared to wlassistant.

Can be closed; but if someone wants to look further into it, I will gladly provide some data.

[Brian Murray (brian-murray)]

Which two lines did you remove? I don't see an obvious difference between the two interfaces files.

Seems I attached the backup instead. I changed from the previous attached one http://librarian.launchpad.net/7325619/interfaces to this:

The above seems only to be part of a solution. Now KNetworkManager detects the wireless card nearly all the time, but after a suspend KNetworkManager sometimes fails to detect it. wlassistant, iwconfig etc. still works in these cases.

[Brian Murray (brian-murray)]

Could you please add the full contents of '/var/log/daemon.log' when network-manager fails to detect your wireless card? Thanks again.

Same problem described above.
I just fresh installed Feisty and at the 1st time Knetworkmanager detected my wireless and I was able to configure the WEP key. At this time KNM requested to open Kwallet and saved the key there . After this configuration, the network worked just fine.
Next morning , after the boot the wireless connection was down and the section "Wireless Devices" didnt show up anymore. Using iwconfig I was able to connect to my access point, but KNM still does not show the missing section.
Im attaching my deamon.log

I'm seeing the same problem as the last comment.

This problem has completely vanished in gutsy and hardy. If anyone still has the issue, feel free to reopen.
