Public bug reported:
Binary package hint: network-manager
On an Thinkpad x201 I've noticed that I can not reconnect to a wireless
AP if I have been disconnected for some reason. This is NOT necessarily
a suspend/resume issue, though it does occur after suspend/resume. I
can recreate this without suspending the system.
So the steps I have used to recreate this, rather annoyingly, today:
Boot system, Network Manager shows me connected to the default AP
Disconnect from AP via Network Manager after an hour or so (noticed this after
disconnection to test some code I'd been working on)
Reconnect to the previously connected AP
Reconnect fails.
This also generates a LOT of messages in Syslog, here's a snipped with
an interesting segfault from wnck-applet too:
