Bug Description
Binary package hint: network-manager
I'm not really sure if this is a duplicate, because it's not clear to me is this the same type of crash as the others I've seen reported. I've used Apport to upload data on this when it happened.
It happens on a Lenovo ThinPad R61i laptop.
What happens is that it crashes from time to time, for no apparent reason, and it stops managing networks. Interfaces not in dire need of management like the ETH0 continue to work unmanaged, but wireless stops working. Restarting the NetworkManager daemon usually solves the problem, however sometimes the wireless adapter stays down, and I'm unable to bring it back up (tried turning on and off by wlan-killswitch, putting the laptop to standby etc.)
Now, I'm not really sure if this is problem with NM bringing down the wlan interface or is it vice versa... It is possible that a faulty driver causes this. However, I've encountered similar problems several Ubuntu versions back, and on a different laptop, so I guess there might be something wrong with the NM.
When NM alone crashes, it's not a problem for me, I just restart the daemon. It might be a problem though, for many ordinary users have no clue what happened, let alone knowing how to restart the daemon...
When the wlan interface goes down together with it, it does become an annoying problem, because I've found no way to bring it up again other then rebooting.
Kind Regards,
Arny

akromic,
This looks to me like an issue with a failing AP or wireless card (or driver), rather than a bug in network-manager. Is anybody else seeing similar problems with different hardware or a different version of Ubutnu or network-manager with this wireless network?
